Lipases are enzymes commonly used in industry. This study describes the production of lipolytic enzyme via a newly isolated strain of Aspergillus oryzae under a submerged fermentation process. Five strains of A. oryzae were isolated from oil-contaminated soil and water as well as dead decaying organic matter. Qualitative screening revealed that A. oryzae RBM4 strain was a lipase producer, and the process was optimized for enhanced production. Incubation time, incubation temperature, initial pH, use of agricultural by-products, nitrogen sources, and substrates were tested. The results revealed that initial pH 5.5(12.7 U/mL/min) in 72 h (19.39 U/mL/min) at 30 °C (27.40 U/mL/min) sorghum (35.66 U/mL/min), NaNO3 (17% more than blank), yeast extract (47.95 U/mL/min), and Shan ghee (58.12 U/mL/min) were the best conditions. Extracellular lipase production was increased up to 78% by applying all the above conditions.
Blood glucose level is regulated by multiple pancreatic hormones, which regulate it by different pathways in normal and abnormal conditions by expressing or suppressing multiple genes or molecular or cellular targets. Multiple synthetic drugs and therapies are used to cure glucose regulatory problems, while many of them are used to cure other health issues, which arise due to disturbance in blood glucose regulations. Many new approaches are used for the development of phytochemicalbased drugs to cure blood glucose regulation problems, and many of the compounds have been isolated and identified to cure insulin resistance or regulate beta cell function or glucose absorption in the guts or GLP-1 homoeostasis or two/more pathways (e.g., either cure hyperglycemia or raise insulin resistance or cure pancreatic beta cell regeneration or augmentation of GLP-1, production of islet cell, production and increased insulin receptor signaling and insulin secretion or decreased insulin tolerance or gluconeogenesis and insulin-mimetic action or production of α-glucosidase and α-amylase inhibitor or conserve islet mass or activate protein kinase A (PKA) and extracellular signal regulated kinases (ERK) or activate AMPK and reduce insulin sensitivity or suppress α-glucosidase activity and activate AMPK and downstream molecules or prevents cell death of pancreatic β-cell and activates SIRT1 or lower blood glucose due to their insulin-like chemical structures or decrease lipid peroxidation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
