Screening and Identification of Alkaline Protease Inhibitor-Producing Marine-derived Actinomyces.

Isolation and Identification of an Alkaline Protease Producing Bacillus from Soil

Screening and identification of biosurfactant producing marine bacteria from the Caspian Sea

Marine microorganisms have unique physiological properties and novel metabolites such as biosurfactant to live in extreme habitats (e.g. oil polluted environment). The aim of this study was to characterize some biosurfactant-producing bacteria collected from sediment and seawater samples from the Caspian Sea. These bacteria were isolated using enrichment method in ONR7a medium with crude oil as...

Isolation and identification of alkaline protease-producing bacterium in the presence of washing-powder from Geinarje hot spring, Ardabil, Iran

Proteases are important industrial enzymes used in different areas of industry, mainly detergent, food and leather industries. In this study, novel alkaline protease-producing bacterium was isolated from Geinarje hot spring and examined for maximum protease activity to be utilized in washing-powder. The isolated bacterium was cultured in mineral salt medium including 2% Skim Milk. Proteolytic a...

Screening and Identification of a Novel Alkaline Lipase Producing Bacterium

The lipase producing bacteria were screened from the soil both qualitatively by Tween 80, rhodamine B agar assays and quantitatively by titrimetry with the objective of finding a bacterial strain capable of producing an alkaline lipase. The higher lipolytic activity of 17.43 U/ml was recorded for the isolate L13. Traditional methods viz. morphological, cultural and biochemical characteristics w...

Identification of a New Marine Bacterial Strain SD8 and Optimization of Its Culture Conditions for Producing Alkaline Protease

While much attention has been given to marine microorganisms for production of enzymes, which in general are relatively more stable and active compared to those from plants and animals, studies on alkaline protease production from marine microorganisms have been very limited. In the present study, the alkaline protease producing marine bacterial strain SD8 isolated from sea muds in the Geziwo Q...
