Endophytes from medicinal plants are potential biocontrol agents against Fusarium oxysporum f. sp. cubense (Foc), which is the causative fungus of banana wilt disease. In present study, endophytic bacterium was isolated Globba racemosa and their antagonistic activities Foc were studied, probable molecular mechanism antagonism predicted by docking studies. The 16SrRNA sequencing confirmed isolate to be Bacillus velezensis CBMB205 (EG2). isolates distortion fungal hyphae illustrated in SEM. metabolites identified FTIR, suggesting presence C-H, CH3 O-H groups. Two major such as β-amyrin dihydroxy octadecenoic acid (DA) LC-MS analysis. Molecular studies suggested that these showed binding with chitin synthase 1 1,3-glucan pathogenic fungi. energy (BE) interaction between synthase-1 (CS-1), (1,3-GS) estimated -10.17 kcal/mol − 9.5 kcal/mol, respectively. BE CS-1 1,3-GS determined -2.43 3.4 current study demonstrated EG2 towards provided a silico also provides insight into developing metabolite-based antifungal for various agricultural applications.

Abstract Biofilm formation and growth is a significant concern for water treatment professionals, as it can lead to the contamination of systems pose threat public health. Biofilms are complex communities microorganisms that adhere surfaces embedded in an extracellular matrix polysaccharides proteins. They notoriously difficult control, they provide protective environment bacteria, viruses, other harmful organisms grow proliferate. This review article highlights some factors favor biofilm growth, well various strategies controlling systems. Adopting best available technologies, such wellhead protection programs, proper distribution system maintenance, filtration disinfection, prevent biofilms A comprehensive multi-faceted approach control reduce occurrence ensure delivery high-quality consumers.

Abstract This study focused on two aspects: to develop a selected functionally competent bacterial community, and its integrated with biostimulant humic acid seaweed extract which was validated enhance wheat growth nutrient content. Wheat maize‐associated isolates (92) were screened for Plant Growth‐Promoting traits (PGPts‐72) Community‐Forming (CFts‐66). 46 possessed both kinds of traits, 20 chosen based high Bonitur scale ratings. Based metabolic diversity, rate, compatibility, 11 grouped make synthetic microbial community (SM). Non‐microbial biostimulants, (HA) (SWE) used, 0.2% HA 1% SWE found be optimal plant growth. SM each SWE, leading products SynBio1 (SM + HA) SynBio2 SWE). Under microcosm study, improved germination by 90.10% 83.80%, respectively. increased chlorophyll content 40.5 SPAD units, root length 15.7%, shoot 18.4%. Field level validations revealed that height 15.76%, 27.16%, flag leaf 21.35% compared the control. The grain yield 40.41% higher than Macro micronutrient analysis seeds treated showed significant improvements. These findings demonstrate potential integrating communities they pave way developing novel bioinoculants sustainable agriculture promoting healthier environment.

Organic farming has emerged as a sustainable solution to the adverse effects (diminished nutritional value, compromised food quality, environmental contamination, and public health hazards) that are usually associated with harmful chemical pesticides. To overcome such loss, one must explore plant-associated microbes naturally occurring root commensal could positively improve crop health. In this review, we highlight importance of bacterial genus Rhodococcus, subset Actinobacteria carries immense potential in enhancing yield is bioremediation toxic pesticides other chemicals soil However, it been noticed few species Rhodococcus pathogenic for plant (R. fascians) well humans/animals equi). But still, majority isolates found be non-pathogenic carry substantial beneficial traits. Here, have attempted comprise those traits different members Rhodococcus. The main emphasis review article major areas enzyme production, phytohormone synthesis, growth regulation, siderophore bioremediation, organic compound degradation, pollution control. Opinions towards applications advanced methodologies utilizing cumulative prospective also discussed sections review. Conclusively, gathers scattered information from past recent literature about bacteria provides future direction how can plant/soil eliminate pollutants.
