Abstract:
It was shown that, depending on the quantity of phosphate in cultivation media, the surface layer of the Bacillus subtilis cell wall can mainly consist of either teichoic or teichuronic acids. It was found that the addition of silicon dioxide particles to the bacterial suspension induces an increase in the negative charge of the cell. This cell response to contact interaction with solid particles is observed in bacteria whose surface components are teichoic acids.

01:20Endospores and Sporulation
Endospores are specialized, dormant cells primarily formed by Gram-positive bacteria, including Bacillus and Clostridium, enabling survival under extreme environmental conditions. Due to their unique composition and formation process, these structures are highly resistant to physical and chemical insults, such as extreme heat, ultraviolet and ionizing radiation, desiccation, and toxic chemicals. Rare instances of endospore-like structures have also been observed in some Gram-negative bacteria,...
01:18Production of Biopesticides
Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
