Deoxyribonucleic acid (DNA) synthesis in bacteriophage phi29-infected Bacillus amyloliquefaciens was studied at 37 and 45 C. Infectious intracellular particles appear at the same time at both temperatures, but the average burst size is reduced 45 to 50% at 45 C. There is a transient inhibition of cellular mass increase at 45 C which is not observed at the lower temperature. In addition, the rat...
Birds were given a new formulation of the Bacillus amyloliquefaciens B-1895 solid-state fermented soybean that retained the spores of the aforementioned organism. Mass dynamics, feed flow rate and broiler performance were observed to evaluate the efficacy of the formulation. At each time point, the live mass was greater than that of the control group, reaching a difference of 7-8% by day 28. A ...
Most isolates belonging to the Bacillus amyloliquefaciens subsp. plantarum clade retain the potential to produce a vast array of structurally diverse antimicrobial compounds that largely contribute to their efficacy as biocontrol agents against numerous plant fungal pathogens. In that context, the role of cyclic lipopeptides (CLPs) has been well-documented but still little is known about the im...
This paper describes the production, the purification and the antilisterial activity of amylolysin, a novel bacteriocin from B. amyloliquefaciens GA1. The strain genome was first analysed using PCR techniques for the presence of gene clusters that direct the synthesis of characterised bacteriocins from B. amyloliquefaciens and the closely related B. subtilis. Our results suggest that amylolysin...
Endospores of proteolytic type B Clostridium botulinum TMW 2.357 and Bacillus amyloliquefaciens TMW 2.479 are currently described as the most high-pressure-resistant bacterial spores relevant to food intoxication and spoilage in combined pressure-temperature applications. The effects of combined pressure (0.1 to 1,400 MPa) and temperature (70 to 120 degrees C) treatments were determined for the...
To analyze the antibacterial activity of Bacillus amyloliquefaciens phage endolysin, nine deletion derivatives of the endolysin were constructed. Each deletion mutant was overexpressed, purified and characterized. The catalytic domain was located on the N-terminal region and the C-terminus had an affinity with the bacterial envelope. The enzymatic activity remained in spite of the deletion of t...
The objective of this study was to evaluate the stimulatory effects of Bacillus amyloliquefaciens SQR9 on dendritic cells (DCs) and to verify its ability to enhance the immune response by modulating DC maturation. The results demonstrated that B. amyloliquefaciens SQR9 can adhere to the nasal epithelium and be taken up by DCs in the nasal mucosa, thereby inducing DC maturation and resulting in ...
