1. Lactic acid bacteria with antimicrobial, proteolytic and lipolytic activities isolated from ovine dairy products
Abstract This study aimed to isolate lactic acid bacteria from sheep milk products and to characterize these microorganisms with a focus on their antimicrobial, proteolytic and lipolytic activities. Raw milk, pasteurized milk, pasteurized cream, and butter samples were collected, lactic acid bacteria were isolated and their proteolytic, lipolytic and antimic

3. Pseudomonas spp. and other psychrotrophic microorganisms in inspected and non-inspected Brazilian Minas Frescal cheese: proteolytic, lipolytic and AprX production potential
RESUMO: O mais consumido no Brasil, o queijo Minas Frescal (QMF) é altamente suscetível à contaminação microbiana e a produção e comercialização clandestina podem representar um risco para a saúde do consumidor. O armazenamento deste produto fresco sob refrigeração, embora mais apropriado, pode favorecer a multiplicação de bactérias psicrotró

4. SYNTHESIS, CHARACTERIZATION AND APPLICATION OF A POLYURETHANE-BASED SUPPORT FOR IMMOBILIZING MEMBRANE-BOUND LIPASE
Abstract This study conducted an assessment of polyurethane foams that were synthesized by one-shot process and used as a low-cost support to immobilize Mucor circinelloides URM 4182 whole-cells presenting high lipolytic activity. Polyols with different molecular weights (1100 to 6000 g mol-1) were applied to synthesize the polymer matrix, and the agitation

5. Surface response methodology for the optimization of lipase production under submerged fermentation by filamentous fungi
Abstract A Plackett–Burman Factorial Design of 16 experiments was conducted to assess the influence of nine factors on the production of lipases by filamentous fungi. The factors investigated were bran type (used as the main carbon source), nitrogen source, nitrogen source concentration, inducer, inducer concentration, fungal strain (Aspergillus niger or A

6. Immobilization of Beauveria bassiana Lipase on Silica Gel by Physical Adsorption
Extracellular lipase from Beauveria bassianastrain CG481 was immobilized by using thirteen different immobilization protocols. Silica gel was chosen as the most suitable adsorbent with 94.8% of activity yield. The adsorption on silica gel did not change the optimum pH (8.5) and temperature (45ºC) values of the free lipase (FL) for lipolytic activity, and it

7. Association of postalimentary lipemia with atherosclerotic manifestations
We identified different lipemic and metabolic responses after the ingestion of a standardized meal by healthy adults and related them to atherosclerotic markers. Samples from 60 normolipidemic adults were collected before and after a liquid meal (40 g fat/m² body surface) at 0, 2, 4, 6, and 8 h for measurements of lipids, free fatty acids (FFA), insulin, ch

8. Seleção de fungos produtores de lipases a partir de resíduos oleosos derivados do saneamento ambiental
The selection of fungi producing lipase from oily residues of environmental sanitation is the main objective of this work. Of 113 fungal isolates obtained, 75 were pre-selected as producers of lipase. Of these,16 were selected by the largest indices enzymatic and four by growth and response to rhodamine-B test, having quantified its specific lipolytic activi

9. Avaliação química e biológica do extrato hidroetanólico de erva-mate (ilex paraguariensis a. st. hil.)
Ilex paraguariensis A. St.-Hil., conhecida como erva-mate, é uma árvore nativa da América do Sul onde as folhas e pequenos ramos secos são usados para preparar o chimarrão. Possui uma composição química complexa, da qual pode-se vislumbrar muitas aplicações potenciais, que poderiam vir a ampliar o emprego da erva-mate e, conseqüentemente, do merca

10. Production of bacteriocin-like substances by lactic acid bacteria isolated from regional ovine cheese
Lactic acid bacteria (LAB) were isolated from ovine milk and cheeses manufactured in the South Region of Brazil. Among 112 bacterial isolates investigated, 59 were chosen through a screening for LAB. Among these 59 strains of LAB, 21% showed antimicrobial, proteolytic and lipolytic activities. Based on this screening, Lactobacillus plantarum LCN 17 and Lacto

12. Efeitos da adição de aminoácidos essenciais livres à dieta e da ausência de nutrientes na atividade de enzimas digestivas e no metabolismo intermediário de juvenis de matrinxã (Brycon amazonicus).
For the nutrients ingested by fish are used for growth and maintenance of the energetical metabolism, they need firstly being absorbed by gastrointestinal tract. However, the most foods ingested cannot be absorbed directly through the gastrointestinal mucosa, since they are largely formed by high molecular weight molecules. The process of transforming large
