Extracellular lipase production from Bacillus subtilis using agro-industrial waste and fruit peels
...ed for the production of lipases by solid-state fermentation (SSF) using agro-industrial wastes as substrate. A total of 14 bacterial strains were isolated, screened and compared for lipase production. Among the evaluated strains, Bacillus subtilis strain NL-39 was selected on the basis of best lipase production. The maximum enzyme activity (34.93 U/ml) was shown by B. subtilis using SSF with soya bean meal. The lipase production by other low cost agro-industr...

...ganisms. Among microbial lipases, the bacterial lipases holds very prominent stance. The specificity of lipases is far-fetched for their point selection and kinds of reactions they undergo on their discernible substrates. Most suitable production plan involves Sub-merged liquid fermentation in fed batch manner using agricultural wastes. Bacterial lipases

Digestive Enzymes Activity with Gut Morphometric Parameter of Carnivorous Fish Wallago attu (Siluridae, Siluriformes)
...gestive enzymes, such as lipases, proteases and amylases in the digestive tract of a wild, freshwater, carnivorous Wallago attu. Wallago attu is a fast growing catfish that belongs to family siluridae under the order siluriformes. It has good market demand as a food fish having high nutritional value, and high protein content in its flesh, Carnivorous in nature. Descriptive data of the studied traits included total body weight, total body length, gut weight, g...
Efficacy of Lipase-Producing, Wax-degrading Bacteria against the Solenopsis Mealybug, Phenacoccus solenopsis Tinsley and the Striped Mealybug, Ferrisia virgata Cockerell (Homoptera: Pseudococcidae) on Cotton

...numerous applications of lipases in chemical, food, pharmaceutical, biotechnological, detergents and surfactants, and agricultural industries and in waste treatment plants proved their importance. In this study, 23 wax-degrading bacterial strains isolated from four mealybug species infesting cotton were screened for lipase production. On the basis of the 16S rRNA gene sequences, lipase-positive strains were classified into six genera, namely, Pseudoxanthomo...
Prevalence of Mycotic Mastitis and Evaluation of Some Virulence Potential of Candida albicans Isolated from Mastitic Goats

Saddam Hussein Mahmoud* and Shaimaa Nabhan Yassein

...uct size (658bp). Phospholipases B1 (PLB1) and the secretion of aspartyl proteinase 1 (SAP1) gene were used to detect C. albicans virulence with 100% and 80% accuracy, respectively, while Hyphal Wall Protein 1 (HWP1) gene was not detected. It is expected that these C. albicans isolates contained a significant proportion of virulence factors that were linked to pathogenicity and the severity of infection. There findings suggest that poor sanitation and a reduct...

...ed that the thermostable lipases had optimum activity at a temperature range of 45oC - 55oC, pH of 7 - 9, and enhanced activity in the presence of Ca2+, Mg2+, and Zn2+, however, Hg2+ caused a slight loss in the lipase activity.

...level. By the actions of lipases, phosphatases and/or kinases; one can act as a precursor for another, thus explaining the reason of their inverse correlation. TAG lipolysis is catalyzed by TAG lipases producing fatty acids and diacylglycerol (DAG). The DAG produced from lipolysis is phosphorylated by diacylglycerol kinase (Dgk1) to form PA. On the other hand, PA is a cell signaling molecule and once increased, it upregulate...

...enzyme activities (i.e., lipases, cellulases, and proteases). In addition, several PGP traits such as phosphate solubilization and the production of siderophores and indol-3 acetic acid were also observed. Molecular identification through 16S rRNA sequencing initially identified all the isolates as Bacillus spp. The multi-locus sequence typing (MLST) scheme, using six housekeeping genes (adk, ccpA, recF, rpoB, sucC, and spo0A) had unveiled distinct allelic pro...
