Pesquisa de bactérias produtoras de lipase no acervo de microrganismos da UTFPR-FB

Abstract

Lipase, a versatile enzyme considered, plays a crucial role in several sectors, including food, pharmaceuticals and detergents. Its use ranges from cheese production to the nature of biodiesel from vegetable oils. Given the relevance of microbial enzymes in the handling of industrial waste, the main objective of this work was to verify the potential for lipase production by strains of Bacillus sp., Pseudomonas aeruginosa and Staphylococcus aureus, microorganisms from the collection of the Microbiology Laboratory of the Federal Technological University of Rio Grande do Sul. Paraná (UTFPR). According to the experimental conditions and methodology imposed, we ensured that none of the strains of microorganisms tested showed lipolytic activity. These results are possibly associated with genetic variability and specific nutritional choices for each microorganism. It is important to highlight the complexity in the production of lipase by different bacterial strains, corroborating the theoretical foundation on the variability of these enzymes and the importance of cultivation strategies adapted to each microorganism. The results positively advance the understanding of lipolytic activity in relevant bacterial strains, offering insights for future research at the intersection of microbiology and biotechnology.
