Latest News on phospholipase : Dec 2021
Phospholipase A2 Phospholipase A2 (PLA2 catalyzes the hydrolysis of the sn-2 position of membrans glyerophospholipids to liberate arachidonic acid (AA), a precursor of eicosanoids including prostaglandins (PGs) and leukotrienes (LTs). The same reaction also produces lysophosholipids, which represent another class of lipid mediators. So far, at least 19 enzymes that posses PLA2 activity have been […]
Latest News on Reticuloendotheliosis : Dec 2021
Leukemic Reticuloendotheliosis The clinical, hematologic, and pathologic findings in 26 cases of leukemic reticuloendotheliosis are presented. A histopathologic correlation of the various forms of leukemia is suggested. Clinically the disease may follow an acute, subacute, or chronic course There is no idiopathic clinical sign or symptom, but the hematologic picture is pathognomonic and is characterized […]
Latest News on Polysaccharides : Dec 2021
Industrial Utilization of Polysaccharides Polysaccharides (excluding starch and its derivatives) are used commercially (for food and cosmetics and industrially) in their natural or modified state. The usefulness of most commercial polysaccharides is based on their capacity to alter the basic properties of water. In addition, polysaccharides have related secondary functions, such as emulsification, suspension, stabilization, […]
Latest News on Bacteriocin : Dec 2021
Bacteriocin-based strategies for food biopreservation Bacteriocins are ribosomally-synthesized peptides or proteins with antimicrobial activity, produced by different groups of bacteria. Many lactic acid bacteria (LAB) produce bacteriocins with rather broad spectra of inhibition. Several LAB bacteriocins offer potential applications in food preservation, and the use of bacteriocins in the food industry can help to reduce […]
Latest News on Cellulolytic : Dec 2021
Why Are Ruminal Cellulolytic Bacteria Unable to Digest Cellulose at Low pH? Ruminant animals depend on cellulolytic ruminal bacteria to digest cellulose, but these bacteria cannot resist the low ruminal pH that modern feeding practices can create. Because the cellulolytic bacteria cannot grow on cellobiose at low pH, pH sensitivity is a general aspect of […]
Latest News on Path Coefficient : Dec 2021
Significance of path coefficient analysis in determining the nature of character association Interrelationships among production characters were determined both by simple correlation and path coefficient analyses, using ecogeographically diverse spring wheat genotypes. Simple correlation analysis indicated that kernel weight correlated positively with plant height and negatively with heading time. Also spike number and kernel weight […]
Latest News on Molecular Methods : Dec 2021
Molecular methods for the assessment of bacterial viability A significant number of pathogenic microorganisms can be found in environmental reservoirs (air, water, soil). It is important to assess the viability status of these organisms to determine whether they pose a threat to public health. Classical methods for determining viability are time consuming. Hence, molecular methods […]
Latest News on microbial biotechnology : Dec 2021
Microbial biotechnology For thousands of years, microorganisms have been used to supply products such as bread, beer and wine. A second phase of traditional microbial biotechnology began during World War I and resulted in the development of the acetone-butanol and glycerol fermentations, followed by processes yielding, for example, citric acid, vitamins and antibiotics. In the […]
Latest News on tissue culture : Dec 2021
Cell and tissue culture The introduction of tissue culture methodology to the biological sciences ushered in a new era of rapid and exciting advances in the fields of virology, morphogenesis, cytology, cytochemistry, toxicology and molecular biology. The widespread use of tissue culture is in no small way due to Dr. Paul’s book, which provided not […]
Probiotics – Isolated from Yak Yoghurt in Qinghai Tibet Plateau of China
The most representative probiotics are lactic acid bacteria, which are typically used in fermented foods, medications, foods and beverages. Yak yoghurt is a kind of fermented milk produced in the Qinghai Tibet Plateau, China, by Tibetan herdsmen. In Yak yoghurt, there are abundant lactic acid bacteria. In this monograph, the anti-constipation, anti-colitis, anti-alcoholic anti-liver injury, […]
