“…After culturing 50 generations of mutant SF66 with the significantly improved antagonist ability, confrontation antagonism experiment was performed on each generation of strains. Results showed that the antagonistic ability of all generations of mutants were basically the same, with slight change in the number of colonies, indicating a good genetic stability of SF66 mutant in antagonistic ability (de Azevedo et al 2021, Beerahassan et al 2021.…”

In the present study six bacterial strains from the soil of grape orchard were isolated and identified. Their antagonistic ability against Uncinula necator and Plasmopara viticola which cause downy mildew and powdery mildew of grapes, respectively were studied. Through phenotypic, physiological and biochemical studies, SF6 strain was identified as Bacillus subtilis which can effectively inhibit the growth of Uncinula necator and Plasmopara viticola of grapes. In order to enhance the antagonistic ability of the SF6 strain, mutation was induced by He-Ne laser radiation and, six mutant strains were obtained. Among the six mutant strains, SF66 showed the strongest antagonistic activity to Uncinula necator and Plasmopara viticola of grapes with its genetic stability. The finding of this research provides important impetus for the development of beneficial antagonistic microorganisms through He-Ne laser radiation breeding. Bangladesh J.

“…The consortium of biocontrol bacteria including B. altitudinis that produces lipase (along with protease) effectively degraded the lipid microfibril framework of Alitropus typus (lsopoda: Aegidae), a notorious parasite of Oreochromis niloticus fish, which demonstrates the prospects of lipase from Bacillus sp. against parasitic fruit pests which have a similar mode of life [148]. Moreover, other Bacillus strains such as B. cereus strain WPD are known entomopathogens of important arthropods such as Litopenaeus vannamei (shrimp) where they cause white patch disease (WPD), and their lipolytic activity is among the most important virulence factors [149].…”

Plant diseases and insect pest damage cause tremendous losses in forestry and fruit tree production. Even though chemical pesticides have been effective in the control of plant diseases and insect pests for several decades, they are increasingly becoming undesirable due to their toxic residues that affect human life, animals, and the environment, as well as the growing challenge of pesticide resistance. In this study, we review the potential of hydrolytic enzymes from Bacillus species such as chitinases, β-1,3-glucanases, proteases, lipases, amylases, and cellulases in the biological control of phytopathogens and insect pests, which could be a more sustainable alternative to chemical pesticides. This study highlights the application potential of the hydrolytic enzymes from different Bacillus sp. as effective biocontrol alternatives against phytopathogens/insect pests through the degradation of cell wall/insect cuticles, which are mainly composed of structural polysaccharides like chitins, β-glucans, glycoproteins, and lipids. This study demonstrates the prospects for applying hydrolytic enzymes from Bacillus sp. as effective biopesticides in forest and fruit tree production, their mode of biocidal activity and dual antimicrobial/insecticidal potential, which indicates a great prospect for the simultaneous biocontrol of pests/diseases. Further research should focus on optimizing the production of hydrolytic enzymes, and the antimicrobial/insecticidal synergism of different Bacillus sp. which could facilitate the simultaneous biocontrol of pests and diseases in forest and fruit tree production.
