    Abstract An experiment on evaluation of five most effective fungicides viz., azoxystrobin 23% SC (Onestar), kasugamycin 3% SL (Kasu-B), flusilazole 40% EC (Cursor), carbendazim 50% WP (Dhanustin) and metiram 55%+ pyraclostrobin 5% WG (Carbrio Top) against A. brassicicola causing leaf spot in cabbage in vitro at 250 and 500 ppm as well as in field in pots receiving two sprays of 0.05 per cent concentration in rabi season was conducted. Among them flusilazole 40% EC was highly efficient as it inhibited 100 per cent mycelial growth of A.brassicicola at both the concentrations. Per cent disease index was found minimum after application of flusilazole 40% EC. All the fungicides were superior over control in increasing the yield of cabbage per pot. The maximum weight of head (410 g) was recorded after foliar application with flusilazole 40% EC (C). This investigation will be helpful to farmers in manageing Alternaria leaf spot of cabbage.

    Abstract The aim of the study is to explore the potential rhizospheric bacterial communities associated with Cannabis sativa L. (Cannabis); growing on the complex pollutant-rich distillery sludge. Seven bacterial species were isolated, among which four potential bacterial species were characterized based on the 16s rRNA sequencing from the rhizosphere sludge of C. sativa; they are Bacillus thuringiensis (MW887525), Bacillus cereus (MW887524), Achromobacter denitrificans (MW886333), Bacillus subtilis (MW886231). The isolated bacteria showed PGPR attributes and potential for ligninolytic enzyme activity. Further, to correlate these bacteria with organic pollutants of sludge, the GC-MS analysis of fresh disposed distillery sludge and after growth of 30 and 60 days C. sativa was also analysed, which showed the conversion and disappearance of compounds by the activity of rhizospheric bacterial communities. Additionally, C. sativa showed a higher metal accumulation pattern of Fe (801.81 ± 0.123)> Cu (275.086 ± 0.069)> Zn (162.15 ± 0.085)> Mn (63.92 ± 0.093)> Pb (28.619 ± 0.192)> Ni (5.02 ± 0.078)> Cd (2.53 ± 0.085)> Cr (1.87 ± 0.079) mg kg

    Abstract The presence of lignin along with other pollutants makes effluent more complex when it is discharged from Pulp and paper mills. The present study investigates the use of biofilm-forming bacteria isolated from pulp paper mill effluent contaminated sites (PPMECSs) for lignin degradation. Isolated biofilm-forming and lignin-degrading bacteria were identified as Bacillus subtilis, Enterobacter cancerogenus, and Bacillus licheniformis by 16S rRNA gene sequencing. Thin liquid chromatography (TLC) analysis showed that the consortium of bacteria produced acyl-homoserine lactone (AHL) as quorum sensing molecules and extracellular polymeric substances (EPS) that protect the bacterial consortium under unfavorable conditions. The potential consortium was able to reduce lignin (900 ppm) by 73% after 8 days of incubation in a minimal salt medium containing kraft lignin and glucose at pH 7.0 and 37 °C as compared to individual strains. The degradation by-products were identified as amides, alcohols, and acids. The major organic pollutants in the effluent were reduced after treatment of the constructed consortium, thus confirming active biotransformation and biodegradation of the lignin. Microscopic examination also indicated the presence of lignin induced biofilm formation. Hence, the constructed biofilm-forming bacterial consortia based on quorum sensing offered a sustainable and effective solution to treat lignin-containing complex pollutants.

    Abstract Wastewater discharged from pulp and paper mills play a major role in environmental pollution and have significant effects on aquatic and terrestrial components. The main focus of this work is to study the potential laccase producing bacterium Bacillus cereus AKRC03 (accession no. MN720581.1) for the biodegradation and toxicity reduction from pulp paper mill wastewater. The isolated strain of Bacillus cereus AKRC03 exhibited up to 78.67% of decolorization and degradation capability for hazardous residual organic pollutants at different nutritional (glucose: 1.0%, peptone: 0.5%) and environmental conditions (pH: 7.0, temperature: 37 °C, agitation: 180 rpm, incubation period: 120 h). The absorption peak of the UV–Vis spectral scan identified the decolorization and degradation pattern for pollutants present in wastewater during treatment. Furthermore, the transformation of major pollutants was exhibited through GC-MS analysis. These were 1-dotriacontanol, 1-heptadecanol, tricosane, 1-(2-hydroxyethoxy) tridecane, and n-[(methylphenyl) methylene]-2-methyl-2-propanamine n-oxide. While silane, (dodecyloxy)trimethyl, (1á,3á,4à)-3,4-bis[dimethyl(4-methylphenyl)silyl]cyclo pentan-1-yl acetate, (2S,3R)-(3-tetradecyloxiranyl)methanol, hexadecanoic acid, 2,3-bis[(trimethylsilyl)oxy]propyl ester, and 2,4,6-tri[4,5-(methylenedioxy)phenyl]-s-triazine appeared as metabolic product after degradation of wastewater. The reduction of toxicity was measured up to 70% for treated wastewater with Phaseolus mungo L seeds and Tubifex tubifex worms. From these findings, it is concluded that the isolated bacterium may be used in the bioaugmentation process for the further detoxification and degradation of discharged pulp paper mill wastewater for environmental safety.

    Abstract Signaling among rhizobacteria and other soil microorganisms is an important mechanism to ensure a successful symbiotic relationship with their phytobionts. Quorum-sensing involves signaling molecules that provide essential networks for communication in the rhizosphere. These signaling molecules relay inter-and-intra-species information that coordinates and controls behavior in mixed communities, and the expression of these signaling molecules changes in response to the chemical cues. The diverse signaling molecules released in the rhizospheric zone affect the structural and physical heterogeneity of the soil and the quantity and identity of rhizobacteria. In general, rhizospheric signaling mechanisms can be categorized into three major types (i) plant to microorganisms signaling through low molecular weight molecules secreted by plants; (ii) interspecies and intraspecies microbial signaling, chiefly through quorum-sensing molecules; and (iii) microorganisms to plant signaling by microbially produced compounds. This review presents knowledge on the signaling molecules of the rhizosphere based on the above three mechanisms. The chemical nature of root exudates and their roles in attracting metabolically active rhizobacteria; the chemical properties of autoinducers secreted by rhizobacteria and their functions in intra- and inter-species interactions, including biofilm formation in the rhizosphere; and influence of quorum sensing on the root architecture, plant defense and biotic and abiotic stress responses, and gene expression are examined. The review provides a thorough understanding of rhizobacteria signaling and will help to develop novel strategies for agriculture, such as the novel use of plant growth-promoting rhizobacteria to enhance crops growth and quorum quenching technique to fight against plant pathogens.
