    Abstract During the processing of poultry, disinfectants are commonly added to cooling water tanks called “chillers” to reduce microorganism populations that can affect food quality. The present study, evaluated the effectiveness of neutral electrolyzed water in a pilot-project-sized chiller for the elimination of pathogenic microorganisms in gizzards and necks chicken. The microbiological analysis of the samples was processed and analyzed in three different food microbiological analysis laboratories. The results demonstrated a maximum microbial load reduction of 1.97686 log CFU/g for Escherichia coli and 1.76313 log CFU/g for Staphylococcus aureus in all samples processed with neutral electrolyzed water. Sodium hypochlorite, a disinfectant in common industrial use, did not achieve significant reductions in microbial loads below those of untreated necks and gizzards for either of the microorganisms in question. Based on these results, this study thus proposes the use electrolyzed water as an alternative disinfectant to sodium hypochlorite for use in chillers; being a sustainable solution that differs from conventional disinfectants in its lack of human or environmental side effects.

    Abstract With the expansion of the green products market and the worldwide policies and strategies directed toward a green revolution and ecological transition, the demand for innovative approaches is always on the rise. Among the sustainable agricultural approaches, microbial-based products are emerging over time as effective and feasible alternatives to agrochemicals. However, the production, formulation, and commercialization of some products can be challenging. Among the main challenges are the industrial production processes that ensure the quality of the product and its cost on the market. In the context of a circular economy, solid-state fermentation (SSF) might represent a smart approach to obtaining valuable products from waste and by-products. SSF enables the growth of various microorganisms on solid surfaces in the absence or near absence of free-flowing water. It is a valuable and practical method and is used in the food, pharmaceutical, energy, and chemical industries. Nevertheless, the application of this technology in the production of formulations useful in agriculture is still limited. This review summarizes the literature dealing with SSF agricultural applications and the future perspective of its use in sustainable agriculture. The survey showed good potential for SSF to produce biostimulants and biopesticides useful in agriculture.

    Abstract Water is essential for the life, but many people lack the accessibility to clean and healthy drinking water and die as a consequence of water-borne infections. Microorganism-mediated water pollution is considered as one of the great concerns to the aquatic environment across the globe. The effluent of fecal matter, hospitals, industry, and cattle farms increase the bacterial load in a water body. Coliform groups of bacteria have long been typically applied as an indicator organism of microbial contamination of the water and historically led to the public health security perception. Among the coliform, Escherichia coli is the indicator of fecal contamination. The multiple tube fermentation technique has been applied as a conventional way to detect coliform in water samples through the fermentation of lactose sugar with production of acid and gas. The potability of water has been measured by the absence or presence of coliform bacteria within the permissible limit referencing the most probable number index value (MPN/100 ml). As fecal pollution indicators, fecal streptococci and Clostridium perfringens are widely used as an alternative to coliform bacteria and have been confirmed via esculin hydrolyzing or catalase-negativity and sulfite reduction tests. Molecular (PCR-based) and enzymatic methods have been applied as a rapid way to detect indicators and other enteric isolates in water samples. Apart from that standard plate count (SPC) of heterotrophic bacteria and biochemical oxygen demand (BOD) techniques also determine the bacterial and organic pollution load in a water sample. Therefore, bacteriological analysis of water indicated that water is polluted by sewage to the extent that it is unsuitable for drinking and also unsuitable for recreation purposes. This is one of the big problems in the twenty-first century is providing everybody with safe drinking or domestic water. The main objective of this article is to highlight the microbial pollution of water with special reference to coliform and its nexus with the environment.

    Abstract Bacterial secondary metabolites (B-SMs) are low molecular weight (< 2.5 KDa) compounds that are produced by bacteria but are not required for their growth or replication. Instead, they are produced to give the organism a selective advantage. They are produced during the stationary/idio phase of the bacterial growth cycle by the gene clusters usually known as biological gene clusters (BGCs) which produce a variety of bioactive substances that boosts plant health directly or indirectly by providing several elements like antibiotics, degradative enzymes, siderophores and etc. These amalgams mainly cover phospholipids, peptides, polypeptides, quinols, polyketides, alkaloids, polyenes, phenazines, volatiles, amino-sugars, macro-lactones and aminoglycosides. B-SMs are widely used as antifungal, antibacterial, antiviral, antitumor and anti-algal bioactive components because of their effective defence against a variety of plant diseases, manage biotic stress, and ability to trigger host response. This review provides insight into a variety of important B-SMs characteristics, including their production, classification based on SMs, and use as defence molecules against pathogen and biotic stress to sustain the plant growth.

    Abstract Purpose Chicken eggshell (ES) is a global biowaste product of poultry industry and an enriched source of calcium required for plant growth. Therefore, the present study has been carried out to assess the potentiality of the combination of ES with vermicompost (VC) and chicken feather protein hydrolysate (CFPH) on growth and yield improvement of Capsicum plants.Method A field study was conducted through randomized block design (RBD) with eight treatments having three replicates for each. Principle Component Analysis (PCA) have performed to analyze the yield related parameters of plant. Nutritional components of VC and ES were also analyzed.Results The PCA analysis of the field experiment data has indicated that the combination of ES, CFPH and VC (in a ratio of 100:10:3) remarkably increased the agronomic parameters of capsicum plant about four folds as compared to its chemical counterpart and control, while together VC and ES strongly influences the characteristics of fruits. The first two dimensions of first and second PCA analysis showed 88.39 and 66.91 percent of the overall dataset inertia respectively, explaining 88.39 and 66.91 percent of the total variability. These two values are higher than their respective reference values of 36.32 and 46.76 percent indicating substantial variability.Conclusion The co-application of ES, CFPH with VC could enhance the yield parameters of crops by enriching the soil with both micro and macronutrients. It also serves as a source of organic compost with concomitant reduction in the use of chemical fertilizers.

    Abstract Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH for its absorption by plants is about 6.5, but in alkaline and acidic soils, most of the consumed P forms an insoluble complex with calcium, iron, and aluminum elements and its availability for absorption by the plant decreases. The supply of P needed by plants is mainly achieved through chemical fertilizers; however, in addition to the high price of these fertilizers, in the long run, their destructive effects will affect the soil and the environment. The use of cheap and abundant resources such as rock phosphate (RP) can be an alternative strategy for P chemical fertilizers, but the solubilization of P of this source has been a challenge for agricultural researchers. For this, physical and chemical treatments have been used, but the solution that has recently attracted the attention of the researchers is to use the potential of rhizobacteria to solubilize RP and supply P to plants by this method. These microorganisms, via. mechanisms such as proton secretion, organic and mineral acid production, siderophore production, etc., lead to the solubilization of RP, and by releasing its P, they improve the quantitative and qualitative performance of agricultural products. In this review, addressing the potential of rhizosphere microbes (with a focus on rhizobacteria) as an eco-friendly strategy for RP solubilization, along with physical and chemical solutions, has been attempted.

    Abstract Manganese (Mn) is essential for plant growth, as it serves as a cofactor for enzymes involved in photosynthesis, antioxidant synthesis, and defense against pathogens. It also plays a role in nutrient uptake, root growth, and soil microbial communities. However, the availability of Mn in the soil can be limited due to factors like soil pH, redox potential, organic matter content, and mineralogy. The excessive use of chemical fertilizers containing Mn can lead to negative consequences for soil and environmental health, such as soil and water pollution. Recent research highlights the significance of microbial interactions in enhancing Mn uptake in plants, offering a more environmentally friendly approach to address Mn deficiencies. Microbes employ various strategies, including pH reduction, organic acid production, and the promotion of root growth, to increase Mn bioavailability. They also produce siderophores, anti-pathogenic compounds, and form symbiotic relationships with plants, thereby facilitating Mn uptake, transport, and stimulating plant growth, while minimizing negative environmental impacts. This review explores the factors impacting the mobility of Mn in soil and plants, and highlights the problems caused by the scarcity of Mn in the soil and the use of chemical fertilizers, including the consequences. Furthermore, it investigates the potential of different soil microbes in addressing these challenges using environmentally friendly methods. This review suggests that microbial interactions could be a promising strategy for improving Mn uptake in plants, resulting in enhanced agricultural productivity and environmental sustainability. However, further research is needed to fully understand these interactions’ mechanisms and optimize their use in agricultural practices.

    Abstract Purpose Chicken feather protein hydrolysate (CFPH) has drawn a significant attention as a component/type of biofertilizer in recent years, because of the beneficial impact on the growth of the plant. The current study aims to evaluate the potential influence of the combination of CFPH with vermicompost (VC) on growth-promotion and yield improvement in tomato plants. Method Feather degrading bacteria were isolated and characterized using 16s-rDNA sequencing, and assessed for biochemical reactions, growth-promoting attributes and keratinase activity. The medium used for feather degradation studies consisted of 0.75% (w/v) of raw feather, with 1% (v/v) of inoculum at 37°C, pH 7.5 and at 120 rpm. A field study was done by randomized block design (RBD) with five treatments in tomato. Results Keratinolytic and feather degrading bacteria isolated and used in this study were identified as Bacillus cereus PKID1 with accession number MT158702. The bacterium gave the highest keratinase activity of 80±0.28 U/ml. The CFPH showed the potential to promote remarkably the germination % of tomato (84.13), rice (87.24), onion (84.13), chilli (84.13), chickpea (73.24) seeds

    field experiment significantly increased plant growth and yield compared with control. Conclusion The principal component analysis of the field experiment as a result of tomato plant-growth, the order of best treatment efficacy for improvement of parameter estimates was as follows: CFPH and VC > CFPH > VC > recommended dose of fertilizers (RDF) > control. Thus, the application of CFPH with VC could improve the productivity of crops and decrease the use of chemical fertilizers.

    Abstract The Camellia sinensis plant provides a wide diversity of black, green, oolong, yellow, brick dark, and white tea. Tea is one of the majorly used beverages across the globe, succeeds only in the water for fitness and pleasure. Generally, green tea has been preferred more as compared to other teas due to its main constituent e.g. polyphenols which contribute to various health benefits. The aim of this updated and comprehensive review is to bring together the latest data on the phytochemistry and pharmacological properties of Camellia sinensis and to highlight the therapeutic prospects of the bioactive compounds in this plant so that the full medicinal potential of Camellia sinensis can be realised. A review of published studies on this topic was performed by searching PubMed/MedLine, Scopus, Google scholar, and Web of Science databases from 1999 to 2022. The results of the analysed studies showed that the main polyphenols of tea are the four prime flavonoids catechins: epigallocatechin gallate (EGCG), epicatechin gallate (ECG), epigallocatechin (EGC), and epicatechin (EC) along with the beneficial biological properties of tea for a broad heterogeneity of disorders, including anticancer, neuroprotective, antibacterial, antiviral, antifungal, antiobesity, antidiabetes and antiglaucoma activities. Poor absorption and low bioavailability of bioactive compounds from Camellia sinensis are limiting aspects of their therapeutic use. More human clinical studies and approaching the latest nanoformulation techniques in nanoparticles to transport the target phytochemical compounds to increase therapeutic efficacy are needed in the future.

    Abstract Plant diseases are still the main problem for the reduction in crop yield and a threat to global food security. Additionally, excessive usage of chemical inputs such as pesticides and fungicides to control plant diseases have created another serious problem for human and environmental health. In view of this, the application of plant growth-promoting rhizobacteria (PGPR) for controlling plant disease incidences has been identified as an eco-friendly approach for coping with the food security issue. In this review, we have identified different ways by which PGPRs are capable of reducing phytopathogenic infestations and enhancing crop yield. PGPR suppresses plant diseases, both directly and indirectly, mediated by microbial metabolites and signaling components. Microbial synthesized anti-pathogenic metabolites such as siderophores, antibiotics, lytic enzymes, hydrogen cyanide, and several others act directly on phytopathogens. The indirect mechanisms of reducing plant disease infestation are caused by the stimulation of plant immune responses known as initiation of systemic resistance (ISR) which is mediated by triggering plant immune responses elicited through pathogen-associated molecular patterns (PAMPs). The ISR triggered in the infected region of the plant leads to the development of systemic acquired resistance (SAR) throughout the plant making the plant resistant to a wide range of pathogens. A number of PGPRs including Pseudomonas and Bacillus genera have proven their ability to stimulate ISR. However, there are still some challenges in the large-scale application and acceptance of PGPR for pest and disease management. Further, we discuss the newly formulated PGPR inoculants possessing both plant growth-promoting activities and plant disease suppression ability for a holistic approach to sustaining plant health and enhancing crop productivity.
