α-Amylase production by thermophilic Bacillus sp strain SMIA-2 cultivated in liquid cultures containing soluble starch as a carbon source and supplemented with 0.05% whey protein and 0.2% peptone reached a maximum activity at 32 h, with levels of 37 U/mL. Studies on the amylase characterization revealed that the optimum temperature of this enzyme was 90°C. The enzyme was stable for 1 h at tempe...
Several products of industrial interest are produced by Bacillus, including enzymes, antibiotics, amino acids, insecticides, biosurfactants and bacteriocins. This study aimed to investigate the potential of two bacterial isolates (P5 and C3) from puba, a regional fermentation product from cassava, to produce multiple substances with antimicrobial and surface active properties. Phylogenetic anal...
This study reports the purification and biochemical characterization of thermostable and acidic-pH-stable α-amylase from Bacillus sp. Iranian S1 isolated from the desert soil (Gandom-e-Beryan in Lut desert, Iran). Amylase production was found to be growth associated. Maximum enzyme production was in exponential phase with activity 2.93 U ml-1 at 50°C and pH 5. The enzyme was purified by isoprop...
Selection of a starter culture with excellent viability and metabolic activity is important for inoculated fermentation of traditional food. To obtain a suitable starter culture for making Chinese sesame-flavored liquor, the yeast and bacterium community structures were investigated during spontaneous and solid-state fermentations of this type of liquor. Five dominant species in spontaneous fer...
The genome of rhizobacterium Bacillus amyloliquefaciens subsp. plantarum strain NAU-B3 is 4,196,170 bp in size and harbors 4,001 genes. Nine giant gene clusters are dedicated to the nonribosomal synthesis of antimicrobial lipopeptides and polyketides. Remarkably, NAU_B3 contains a large inversion within the central portion of the genome.
Bacillus amyloliquefaciens strain EBL11 is a bacterium that can promote plant growth by inhibiting the growth of fungi on plant surfaces and providing nutrients as a nonchemical biofertilizer. The estimated genome of this strain is 4.05 Mb in size and harbors 3,683 coding genes (CDSs).
We announce here the genome sequence of Bacillus amyloliquefaciens strain UCMB5036, a plant growth-promoting bacterium isolated from a cotton plant. Its genome contains gene clusters involved in nonribosomal synthesis of secondary metabolites known for their antimicrobial activities. The availability of this genome will provide novel insights into plant-bacterium-associated activities.
The structural gene for a thermostable alpha-amylase from Bacillus stearothermophilus was cloned in plasmids pTB90 and pTB53. It was expressed in both B. stearothermophilus and Bacillus subtilis. B. stearothermophilus carrying the recombinant plasmid produced about fivefold more alpha-amylase (20.9 U/mg of dry cells) than did the wild-type strain of B. stearothermophilus. Some properties of the...
The outline of our work delineates the isolation and evaluation sun screening activity melanin producers such as Pseudomonas mosselli STGRDS1, putida STGRDS3, Bacillus amyloliquefaciens STGRDV11, subtilis STGRDV5 cereus STGRDT12. All isolates were tested against fungal STGRDM1, which was used control throughout study. Sun Protection Factor (SPF) formulated creams containing 5% 10% determined wi...
Ultra high pressure homogenization (UHPH) opens up new areas for dynamic high pressure assisted thermal sterilization of liquids. Bacillus amyloliquefaciens spores are resistant to high isostatic pressure and temperature and were suggested as potential surrogate for high pressure thermal sterilization validation. B. amyloliquefaciens spores suspended in PBS buffer (0.01 M, pH 7.0), low fat milk...
