Antagonistic activity 100 strains of Bacillus bacteria towards to museum and actual strains of phytopathogenic bacteria and fungy was defined. Relation between level of antagonistic activity to phytopathogenic bacteria and genus accessory of the last was shown. The medium level of antagonism to fungal phytopathogens at 30% of the studied strains of Bacillus bacteria was shown. 5 strains of Bacillus sp. with high and medium levels of antagonism to phytopathogens bacterial and fungy nature was selected and considered as perspective for creation of biological preparations for plant protection.

Poly-gamma-glutamic acid (γ-PGA) is mainly synthesized by glutamate-dependent strains in the manufacturing industry. Therefore, understanding glutamate-dependent mechanisms is imperative. In this study, we first systematically analyzed the response of Bacillus subtilis SCP017-03 to glutamate addition by comparing transcriptomics and proteomics.

In this study, three pyridine- and four thiophene-containing chalcone derivatives were synthesized via Claisen-Schmidt condensation reaction, where five derivatives were new. Different spectral analyses (IR, H NMR, HRMS) clarified the structures and these proposed compounds were screened for antimicrobial activity by the agar disc diffusion technique. Compound was conspicuously active against most of the bacterial and fungal strains.

Background: Maintaining gut health is a persistent and unresolved challenge in the poultry industry. Given the critical role of gut health in chicken performance and welfare, there is a pressing need to identify effective gut health intervention (GHI) strategies to ensure optimal outcomes in poultry farming. In this study, across three broiler production cycles, we compared the metagenomes and performance of broilers provided with ionophores (as the control group) against birds subjected to five different GHI combinations involving vaccination, probiotics, prebiotics, essential oils, and reduction of ionophore use.

Thermophilic bacteria (TB) pretreatment is an efficient and environmentally friendly way for accelerating sludge hydrolysis. In this study, a complete comparison of the hydrolysis performance of Bacillus sp. AT07-1 (X1), Parageobacillus toebii X2 (X2), Geobacillus kaustophilus X3 (X3) and Parageobacillus toebii R-35642 (X4) was performed.

Malachite green (MG) is used as a dye for materials such as wood, cotton, and nylon, and is used in aquaculture to prevent fungal and protozoan diseases. However, it is highly toxic, with carcinogenic, mutagenic, and teratogenic properties, resulting in bans worldwide. Despite this, MG is still frequently used in many countries due to its efficacy and economy.
