This study aims to investigate the lipase-producing capabilities of the isolated strain Aspergillus niger Qurna and to provide an analysis of contemporary scholarly contributions on the subject. Our objective is to offer a comprehensive survey of recent advancements in lipase production from Aspergillus niger, juxtaposing our findings with those from other relevant studies. Significant lipase activity was observed within the Aspergillus niger Qurna isolate, with a precipitation area exceeding 55 mm by the fifth day of tracking lipase activity via a chromogenic method. The variation in the precipitation zone size among different Aspergillus niger isolates might be attributable to genetic differences or environmental influences on gene expression. Upon comparing the Aspergillus niger Qurna isolate with international isolates, it was determined that the local Aspergillus niger isolate exhibited superior lipase activity. This makes it a promising candidate for biotechnological applications, including its potential use in food, pharmaceutical, detergent, and chemical industries. Therefore, the identification of Aspergillus niger strains with high lipase activity holds significant importance for biotechnological applications.

“…In the study of Souza, et al (2016), they investigated the accumulation of lipids in daily with the aid of lipophilic dye. Kadhim and Alrubayae (2019) showed the method as fast to select filamentous oleaginous fungi. Compared to fluorescence staining methods, which require specialized instrumentation (e.g., Nile red), the Sudan Black B technique is a simple and easy to access method.…”

Polyunsaturated fatty acids (PUFAs) are essential for human functions and can be used in nutraceuticals; however, traditional sources are environmentally unsustainable. A promising strategy to reduce the production costs of PUFAs is the use of economical agro-industrial sources as substrates in culture media for oleaginous microorganisms. In this study, we investigated the potential of the fungus Lichtheimia hyalospora UCP 1266 (isolated from the Caatinga soil, Brazil) in the production of PUFAs, through the metabolic conversion of alternative substrates crude glycerol (CG) and corn steep liquor (CSL). The cultivation of L. hyalospora UCP 1266 in medium containing glucose (Synthetic Medium for Mucorales - SMM) yielded 2.1 g/L of biomass and 0.6 g/L of total lipids. However, assay 4 of the 22 full-factorial design, with CG 8% and CSL 8%, provided higher yields of biomass (15.5 g/L) and total lipids (12.8 g/L). The lipids produced in this medium presented a composition of saturated, monounsaturated and polyunsaturated fatty acids (SFAs=35.13%, MUFAs=46.09% and PUFAs=18.14%). The microorganism proved to be promising in the production of omega 6 (linoleic acid, C18:2), γ-linolenic acid (C18:3), omega 3 (α-linolenic acid, C18:3) and omega 9 (oleic acid, C18:1). The results indicated L. hyalospora UCP 1266 as an oleaginous fungus with great potential for use in the development of nutraceutical ingredients for food or applied in cosmeceuticals and/or nutricosmetics.
