Proteolytic Activity of Ruminal Bacteria: Studies With Butyrivibrio Fibrisolvens (Protease, Anaerobe, Protein)
… of enzyme synthesis largely paralleled growth. Protease production was not subject to induction as enzyme activity was always present regardless of the nitrogen source or carbohydrate source provided in the growth medium. Production of proteolytic activity may be subject to repression as ammonia …

Molecular biology studies on the extracellular serine proteases of Vibrio alginolyticus
… that produces several extracellular serine proteases and a collagenase during the stationary growth phase. The aim of this study was to investigate alkaline serine protease production by this organism, and to attempt the cloning and expression of a V.alginolyticus protease gene in …

Role of msaA Gene in Regulation of the msaABCR Operon and Biofilm Development in <i>Staphylococcus aureus</i>
… of regulation of <em>sarA</em>, extracellular protease production, and biofilm formation. Deletion of <em>msaA</em> led to the over-expression of <em>sarA</em>, decreased protease production, and increased biofilm formation, which is in contrast to <em>msaC</em> and <em>msaABCR</em> deletion …

SRV REGULATION OF STREPTOCOCCAL BIOFILM DISPERSAL AND ITS IMPACT ON VIRULENCE
… Several groups have shown that regulation of protease production may play a role in the transition from localized to systemic infection. GAS has evolved the ability to colonize a variety of distinct host sites, and one possible mechanism for colonization is through the formation of a biofilm. …

Isolation of a Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production
… factors were performed. Results showed that the production of pigments, haemolysin, and rhamnolipids were significantly decreased from PAO1. Elastase and casein protease production were also moderately decreased. In the Caenorhabditis elegans infection model the nematodes fed the ATCase mutant …

Identification and Characterization of msaB Gene Involved in Biofilm Formation and Virulence in <i>Staphylococcus aureus</i>
… major <em>msaB</em> phenotypes: pigmentation, protease production, biofilm formation, and rate of cell death. Deletion of <em>msaB</em> resulted in the similar <em>msaC</em> and/or <em>msaABCR</em> deletion mutant, thus showing the importance of this gene in this operon. The mutant showed …

Regulation of nitrogen metabolism in vibrio alginolyticus
… alginolyticus produced histidase at 30°C but production of histidase was repressed by either incubation at 37°C or a lack of oxygen. A similar regulation system by temperature and oxygen has been reported for collagenase and prntease production by V. alginolyticus (Hare et al., 1981). V. …

Production, purification and properties of Bacillus thuringiensis neutral protease
… enzyme. This study concerns the conditions for production, the.purification and the properties of this enzyme. It was found in studies relating to production of protease that B. thuringiensis var. kurstaki (HD-1) produced a considerable quantity of the enzyme in a protease production medium …

Evidence of Water to Human Transmission of Aeromonas Hydrophila: Critical Role of Quorum Sensing in Bacterial Virulence & Host Response
… regulating type 6 secretion effectors, metallo-protease production, and biofilm formation. In a septicemic mouse model, the ΔahyRI mutant was also attenuated as compared to the parental strain of A. hydrophila. In addition, we demonstrated that AHLs possess immunomodulatory and protective roles …

Evolution and phenotypic diversification in serratia marcescens biofilms
… formation, swimming and swarming motilities, protease production, and hemolysin production. It was also demonstrated that phenotypic diversification contributed to a varying degree of resistance to protozoan predation, and bacterial pathogenecity in Caenorhabditis elegans, highlighting the …

Comparative and Functional Analysis of Gene Expression in Ophiostoma Species
… was likely the preferred method of ATP production in O. floccosum blastospores. However, the putative identification of genes encoding alcohol dehydrogenases within O. floccosum ESTs and the presence of homologues in other Ophiostoma species would suggest that these Ophiostoma species …
