Project aims 1. Feasibility studies of Bacillus subtilis as an expression host for the production of therapeutically important proteins through high cell density fermentations. 2. Studies on intein mediated purification of therapeutically important proteins expressed in Bacillus subtilis. 3. Case studies with a few proteins of research/commercial relevance including malaria proteins that are li...

pGIAK1 is a 38-kb plasmid originating from the obligate alkaliphilic and halotolerant Bacillaceae strain JMAK1. The strain was originally isolated from the confined environments of the Antarctic Concordia station. Analysis of the pGIAK1 38,362-bp sequence revealed that, in addition to its replication region, this plasmid contains the genetic determinants for cadmium and arsenic resistances, put...

Dormant spores of Bacillus species lack ATP and NADH and contain notable levels of only a few other common low mol wt energy reserves, including 3-phosphoglyceric acid (3PGA), and glutamic acid. Recently, Bacillus subtilis spores were reported to contain ~ 30 μmol of L-malate/g dry wt, which also could serve as an energy reserve. In present work, L-malate levels were determined in the core of d...

In this study, we have identified a bacterium that can inhibit the growth of Staphylococcus aureus, and further analyzed its antibacterial activity and other biological characteristics and laid the foundation for its future application. Through isolation and culture of the unknown bacteria, the culture characteristics, morphology observation, biochemical test, preliminary antibacterial test, 16...

Field studies were conducted at Veselopodilska Experimental Breeding Station Institute Bioenergy Crops Suga...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

We report here the 4.092-Mb high-quality draft genome assembly of a newly isolated poly-γ-glutamic acid-producing strain, Bacillus subtilis Ia1a. The genome sequence is considered a critical tool to facilitate the engineering of improved production strains. Exopolysaccharides and many industrially important enzymes can be produced by this new strain utilizing different carbon sources.

Bacillus subtilis is a ubiquitous Gram-positive model organism. Here, we describe the complete genome of B. subtilus myophage Grass. Aside from genes encoding core proteins pertinent to the life cycle of the phage, Grass has several interesting features, including an FtsK/SpoIIIE protein.

Bacillus subtilis strain NKYL29 is an antimicrobial-peptide-producing strain isolated from the soil of Ranzhuang Tunnel in Hebei Province, China. Here, we present the draft genome of this strain, which provides the genetic basis for application of the antimicrobial peptide.
