Abstract	Traditional antimicrobial antibiotics are increasingly suffering from the emergence of multidrug resistance among pathogenic microorganisms. The antibiotic era is threatened by the ruthless rise of resistance in bacterial infections. A significant role in these resistance profiles is attributed to multidrug efflux pumps. Hence, much effort is being directed towards developing new compounds to overcome this problem. During our screening program of efflux pumps inhibitors (EPI) produced by bioactive Moroccan Actinobacteria, 210 isolates were screened for their antibacterial activities against

Abstract	SARS-CoV-2 has caused a huge pandemic affecting millions of people and resulting innumerous deaths. A better understanding of the correlation between binding antibodies and neutralizing antibodies is necessary to address protective immunity post-infection or vaccination. Here, we investigate the humoral immune response and the seroprevalence of neutralizing antibodies following vaccination with adenovirus-based vector in 177 serum samples. A Microneutralization (MN) assay was used as a reference method to assess whether neutralizing antibody titers correlated with a positive signal in two commercially available serological tests:a rapid lateral flow immune-chromatographic assay (LFIA) and an enzyme-linked Fluorescence Assay (ELFA). Neutralizing antibodies were detected in most serum samples (84%). COVID-19 convalescent individuals showed high antibody titers and significant neutralizing activity. Spearman correlation coefficients between the serological and neutralization results ranged from 0.8 to 0.9, suggesting a moderate to strong correlation between commercial immunoassays test results (LFIA and ELFA) and virus neutralization.

Abstract	Soil actinomycetes explorations appear to be an efficient alternative as biofertilizers to optimize the use of phosphorus (P) resources and enhance plant growth. This research aimed to explore the distribution of actinomycetes isolated from four different rhizospheric Moroccan oat soils and to investigate their potential for P solubilization. The distribution of actinomycetes was significantly more abundant in Settat (9.68%), Tangier (7.38%), and Beni Mellal (6.87%) than in the Merchouch-Rabat (4.90%) region. A total of 235 actinomycete strains were isolated from all sites and tested for their ability to grow on a synthetic minimum medium (SMM) containing insoluble natural rock phosphate (RP) or synthetic tricalcium phosphate (TCP) as the unique P source. One hundred forty-three isolates (60.8%) had the ability to grow in the SMM with RP whereas only twenty-five isolates (17%) had the most active growth using the SMM with TCP. Eight isolates with the most active growth in solid SMM were selected for their P solubilization abilities in liquid SMM cultures. The highest amount of P solubilized was 163.8 µg/mL for RP and 110.27 µg/mL for TCP after 5 days of culture. The biosolubilization process of AM2, the most efficient RP and TCP solubilizing strain, probably implied the highest excretion of siderophore substances.

Abstract	PURPOSE: Phosphorus (P) and potassium (K) shortages inhibit crop production, and soil borne plant diseases such as root rot by Fusarium spp. can cause extensive damage to crops. Streptomyces bellus (SB) and S. saprophyticus (SS) solubilize P and K and inhibit sugar beet (Beta vulgaris L.) associated Fusarium strains in laboratory conditions. METHODS: To address their performance in vivo, their effects on sugar beet growth and root rot development was tested. RESULTS: The tested strains showed a significant beneficial effect on growth and yield parameters of sugar beet when mixed in the soil with insoluble natural rock phosphate (RP) and/or K mineral orthoclase (OT). Compared to the non-inoculated treatment, the highest shoot and root dry biomass were recorded with RP+OT+SB. Highest P and K levels in leaves were with OT+SB and RP+SB, and the treatment RP+OT+SB increased both soil P and K. Interestingly, these SS and SB strains exhibited high protection effects of 100% and 75%, respectively, when the soil was infested by F. equiseti and F. fujikuroi, causal agents of root rot disease of sugar beet in Beni Mellal region. CONCLUSIONS: These results can be exploited to mitigate the detrimental impacts of nutrient limitation for and disease susceptibility of sugar beet.

Abstract	The water is used in many textile manufacturing steps beyond cleaning. The quantity and the significant chemical load of the effluents generated constitute the primary challenge of the textile industry. In order to discover new sustainable methods to overcome this problem, the aim of this research was to study the potential for degradation of Reactive Blue 214, Reactive Red 195, and Reactive Yellow 145 using a dye degrading bacterium. Sequencing analysis reveals it to be Klebsiella pneumoniae MW815592. This strain completely decolorized artificial effluent (200 mg/L) after 42 h at pH 9 and 46 °C. The decolorization rate increased in the presence of glucose and yeast extract (2 g). In addition, our finding revealed that the decolorization is due to biodegradation rather than adsorption on the bacterial surface.

Abstract	The characterized 10 Streptomyces isolates were previously selected by their abilities to solubilize phosphates. To investigate whether these isolates represent multifaceted plant growth-promoting rhizobacteria (PGPR), their potassium-solubilizing, auxin-producing and inhibitory activities were determined. The 10 Streptomyces spp. yielded a variable biomass in the presence of insoluble orthoclase as the sole potassium (K) source, indicating that they were able to extract different amounts of K from this source for their own growth. Three strains (AZ, AYD and DE2) released soluble K from insoluble orthoclase in large amounts into the culture broth. The production levels ranged from 125.4 mg/L to 216.6 mg/L after 5 days of culture. Only two strains, Streptomyces enissocaesilis (BYC) and S . tunisiensis (AI), released a larger amount of soluble K from orthoclase and yielded much more biomass. This indicated that the rate of K released from this insoluble orthoclase exceeded its consumption rate for bacterial growth and that some strains solubilized K more efficiently than others. The results also suggest that the K solubilization process of AZ, AYD and DE2 strains, the most efficient K-solubilizing strains, involves a slight acidification of the medium. Furthermore, these 10 Streptomyces spp. were able to secrete indole acetic acid (IAA) in broth medium and ranged from 7.9 ± 0.1 µg/mL to 122.3 ± 0.1 µg/mL. The results of the antibiosis test proved the potential of the 10 tested strains to limit the growth of fungi and bacteria. In dual culture, S . bellus (AYD) had highest inhibitory effect against the three identified fungal causal agents of root rot of sugar beet: Fusarium equiseti and two F . fujikuroi at 55, 43 and 36%, respectively. Streptomyces enissocaesilis (BYC), S . bellus (AYD) and S . saprophyticus (DE2) exhibited higher multifaceted PGPR with their potassium-solubilizing, auxin-producing and inhibitory activities, which could be expected to lead to effectiveness in field trials of sugar beet.
