Rapid purification of extracellular tannase using polyethylene glycol–tannic acid complex

Rapid screening of tannase producing microbes by using natural tannin

Use of natural tannin in the screening of tannase producing microbes is really promising. The present work describes about the possibility and integrity of the newly formulated method over the previously reported methods. Tannin isolated from Terminalia belerica Roxb. (Bahera) was used to differentiate between tanninolytic and nontanninolytic microbes. The method is simple, sensitive and superi...

Rapid purification of HU protein from Halobacillus karajensis

The histone-like protein HU is the most-abundant DNA-binding protein in bacteria. The HU protein non-specifically binds and bends DNA as a hetero- or homodimer, and can participate in DNA supercoiling and DNA condensation. It also takes part in DNA functions such as replication, recombination, and repair. HU does not recognize any specific sequences but shows a certain degree of specificity to ...

Rapid Detection of Vibrio Cholera by a Coagglutination Complex using Staphylococcus aureus Including Protein A

Introduction: Vibrio cholera is a gram-negative bacterium that causes cholera which is an acute diarrheal illness. Cholera outbreak mostly happens in hot seasons when the bacteria reproduce rapidly in water contaminated with feces. Severe diarrhea and mortality have been the prevalent symptoms of cholera which affect the hygienic status and economic features of humans during centuries. There is...
