Abstract: A significant increase has been observed in the use of enzymes as biocatalysts in various industrial processes, as they selectively catalyze substrates, yielding purer products and thereby reducing production costs and the generation of unwanted compounds. Research on lipase production has powerful biotechnological potential due to the wide range of reactions they catalyze in both aqueous and organic media, enabling their application in various processes such as biodiesel production, detergents, cosmetics, food, and others. This study aimed to perform a qualitative and quantitative screening of different filamentous fungi with potential for lipase production. Initially, fifteen filamentous fungi isolated from artisanal Minas cheese with a bloomy rind were replicated on a solid culture medium suitable for lipase activity at 30°C for 48 hours, and four strains identified as QCPCB3, QMEACB8, QBPS232, and QBPL233 were selected, with enzymatic halos measuring 4.65 cm, 3.70 cm, 3.50 cm, and 3.50 cm, respectively. These four isolates were subjected to quantitative determination of lipase production in submerged Carvalho-Peixoto (CP) medium containing soybean oil as the carbon source at 30°C for 120 hours, with the highest lipolytic activity observed in QBPL233 at 3.62 U.mL⁻¹, followed by QMEACB8 at 3.48 U.mL⁻¹ and QCPCB3 at 3.42 U.mL⁻¹. Based on these results, it can be concluded that qualitative screening is important; however, actual enzymatic activity is obtained through quantification, and there is no direct relationship between the microorganism's size and enzyme production. Therefore, the importance of optimizing enzyme production processes for biotechnological application is highlighted.
