This study was conducted with the aim to isolation bacterial strains capable of antagonism Cercospora arachidicola (Passalora arachidicola) causing brown spot in peanut. From 3 soil samples collected rhizosphere peanut grown Tay Ninh province, Vietnam, 10 were found having antagonistic action arachidicola. After 5 days testing, efficiency all isolates ranged from 33.33±1.28 60.183±0.927%. Study...

Endophytes form symbiotic relationships with plants and constitute an important source of phytohormones and bioactive secondary metabolites for their hosts. To date, most studies of endophytes have focused on the influence of these microorganisms on plant growth and physiology and their role in plant defenses against biotic and abiotic stressors; however, to the best of our knowledge, the abili...

Plant growth-promoting rhizobacteria (PGPR) are known in various cropping systems to increase plant growth and vigor, as well as induce resistance to pathogens and pests. A commercial soil amendment containing a mixture of two species of Bacillus PGPR (Bacillus subtilis and Bacillus amyloliquefaciens) was evaluated for impact on germination and initial growth of bell pepper plants, efficacy aga...

In this research, antagonistic activity of two Bacillus species isolated from digestive tract of marine fish and culture pond of sea cucumber was studied. The inhibitory activity of Bacillus spp. isolates against some common pathogenic bacteria of fish was assessed using the agar diffusion method. The strain of B. subtilis G024 exhibited antimicrobial activity against Vibrio anguillarum, V. har...

Thermostable α-amylase is of great importance in the starch fermentation industry; it is extensively used in the manufacture of beverages, baby foods, medicines, and pharmaceuticals. Bacillus amyloliquefaciens produces thermostable α-amylase; however, production of thermostable α-amylase is limited. Ion-beam implantation is an effective method for mutation breeding in microbes. We conduct...
