Isolation, Cellulase Activity Test and Molecular Identification of Selected Cellulolytic Bacteria Indigenous Rice Bran

Isolation and molecular identification of carotenoid-producing bacteria

The production of pigments from bacteria is significant due to the low cost, high yield and ease of extract compared with other sources. Carotenoids are one of the most important pigments with antioxidant properties which are the precursor of vitamin A synthesis and have antibody overproduction ability, anti-tumor activity and inhibitory effect on the cardiovascular disease. The present study a...

Isolation of Cellulolytic Bacteria

Isolation and Molecular Identification of Keratinase-Producing Bacteria from the Sludge of Qeshm Island

ABSTRACT           Background and Objectives: Keratinase is an enzyme commonly used in the production of detergents, cosmetics, drugs, leather, and other industries. Considering the high cost of traditional methods for decomposition of feather, hair, hooves, nails, and wool that contain high levels of keratin, their biodegradation with keratinase-...

Cellulase-assisted extraction of oligosaccharides from defatted rice bran.

Defatted rice bran was subjected to cellulase treatment in order to increase its extractable oligosaccharides. Various combinations of enzyme concentration (0%, 0.5%, 1.0%, and 2.0%), temperature (room, 30, 40, and 50 degrees C), and time (1, 3, 5, and 16 h) were tested to identify the optimum extraction conditions. The saccharide content and composition of the extracts were analyzed by high-pe...

Isolation and molecular identification of bacteria producing alkaline phosphatase enzyme from environmental sources

Alkaline phosphatase (ortho phosphate, monoester hydrolase phosphoinositide E. C. 3.1.3.1) is a non-specific metalloproteinase enzyme that is located inside periplasmic space of bacteria. This enzyme is used to measure freshwater sediment in genetic engineering for cleaning water. Isolation and molecular identification of the bacteria producing alkaline phosphatase and comparison of its product...
