In the present study, 120 yeast isolates from different sources (active sludge, soil, and wastewater samples obtained from petroleum refinery and soil contaminated by petroleum) were obtained. The yeast isolates were screened for lipase production and twelve of the isolates (D3, D17, D24, D27, D30, D38, D40, D42, D44, D46, D56, and D57) exhibited lipase activity. Molecular characterization of the yeasts showing the lipase production was performed with RFLP of ITS1-5.8S-ITS2 and 18S rRNA and sequence analysis of D1/D2 domain of 26S rRNA. The 26S rRNA sequencing revealed that four new strains, D38, D40, D44 and D57 identified as Rhodotorula slooffiae, Candida davisiana, Cryptococcus diffluens, and Cryptococcus uzbekistanensis, respectively, are lipase producing yeast species. This study is the first report showed lipase production by these species. The other lipase producing strains identified as Candida parapsilosis (D3), Rhodotorula muciloginosa (D17 and D42), Cryptococcus albidus (D24, D27, D30, and D56), and Wickerhamomyces anomalus (D46).

Background: Multiple AD risk genes are implicated in lipid metabolism, and plasma and brain lipid levels are altered in AD. Astrocytes are enriched in key lipid-related factors and are likely contributors to altered lipid homeostasis in AD. We hypothesize that APP/Aβ-related pathology and neuroimmune factors modulate astrocytic gene transcription that promote maladaptive changes in lipid pathways, including aberrant astrocytic production and release of lipids that could affect Aβ pathology and neuronal deficits.

Enzyme-modified butter (EMB) is well-known for its rich flavour, which is primarily defined by the process of enzymatic hydrolysis. This study employed lipidomics and flavouromics to assess the differences between EMBs and to uncover the intrinsic links between volatile organic compounds (VOCs) and lipids. Approximately 273 lipids and 82 VOCs were identified in butter.

Lipases are triacylglycerol hydrolases with various potential applications because of their different physical properties. Most lipase producers are extracellular in nature and are created using solid-state fermentation and submerged fermentation methods. The fungal, mycelial, and yeast lipases are produced using various solid substrates through the solid-state fermentation method.
