in modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as tem-1, tem-2, and shv-1 are transferred among bacterial species. the genes coding the production of esbl are of...

OBJECTIVES Enzymes are commonly used in the baking industry, as they can improve dough quality and texture and lengthen the shelf life of the final product. There is little published information highlighting exposure to enzymes (other than fungal alpha-amylase) in the baking industry, therefore the purpose of this study was to identify antibodies and develop assays for the measurement of a vari...

background: the clinical diagnosis of meningitis is crucial, particularly in children. the early diagnosis and empiric an­tibi­otic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16srdna frag­ment which is produced by universal primers led up fast and sensitive determination. the purpose of this study was to investi­gate a rapid method fo...

The physical and chemical properties of six crude phytase preparations were compared. Four of these enzymes (Aspergillus A, Aspergillus R, Peniophora and Aspergillus T) were produced at commercial scale for the use as feed additives while the other two (E. coli and Bacillus) were produced at laboratory scale. The encoding genes of the enzymes were from different microbial origins (4 of fungal o...

Organic matter in the ocean water column is produced predominantly as high molecular weight matter that cannot be directly assimilated by bacteria. Consequently, bacterial extracellular ectoenzymes act in the processing of the polymer in the sea. Proteins are important substrates for bacterial growth and sources of organic carbon and nitrogen. However, little is known about the protein degradat...

Bacteria and Eukarya share essentially the same family of protein-serine/threonine kinases, also known as the Hanks-type kinases. However, when it comes to protein-tyrosine phosphorylation, bacteria seem to have gone their own way. Bacterial protein-tyrosine kinases (BY-kinases) are bacterial enzymes that are unique in exploiting the ATP/GTPbinding Walker motif to catalyze phosphorylation of pr...
