Bacteria

Bacillus cereus mitigates the negative effects of proteinase inhibitors produced by the host plant.
Detoxification Enzymes

2013
Bacteria
Extracellular

Bacillus cereus processes serine- and cysteine-proteinase activities (protein degradation).
Protein Degradation

Bacteria
Extracellular

Bacillus cereus acts against plant-derived protease inhibitors, potentially aiding in pest control.
Plant Defense Modulation

2013
Bacteria

Bacillus subtilis produces chymotrypsin-like proteases, likely assisting the insect in proteinaceous food digestion and adaptation to protease inhibitors of host plants.
Digestive Enzymes

Bacillus sp.

Bacillota
Bacteria

Bacillus sp. produces lipase in the gut environment.
Lipase

2011
Bacteria

Gut bacteria (midgut bacterial overload) confers an advantage against certain entomopathogens such as B. thuringiensis.
