3. AVALIAÇÃO DE DIFERENTES CULTURAS STARTERS NA ELABORAÇÃO DE SALAME TIPO ITALIANO
Resumo O Salame Tipo Italiano produzido no Brasil é predominantemente obtido de carne suína, com maturação aproximada de 30 dias, atingindo pH em torno de 5,4. O uso das bactérias do gênero Lactobacillus como culturas iniciadoras propicia o processo de fermentação e a obtenção de produtos uniformes e seguros, com redução do tempo de maturação d

4. 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

5. Characterization of Acinetobacter spp. from raw goat Milk
RESUMO: O leite de cabra tem sido sugerido como alternativa ao leite de vaca, sendo uma opção com melhor digestibilidade e menor alergenicidade. No entanto, a presença de bactérias contaminantes pode afetar significativamente a segurança do produto. Neste trabalho, relatamos o isolamento e caracterização de Acinetobacter spp. isolados de amostras de

6. Predictive modeling of Pseudomonas fluorescens growth under different temperature and pH values
Abstract Meat is one of the most perishable foods owing to its nutrient availability, high water activity, and pH around 5.6. These properties are highly conducive for microbial growth. Fresh meat, when exposed to oxygen, is subjected to the action of aerobic psychrotrophic, proteolytic, and lipolytic spoilage microorganisms, such as Pseudomonas spp. The spo

7. LIPASE PRODUCTION BY Aspergillus niger GROWN IN DIFFERENT AGRO-INDUSTRIAL WASTES BY SOLID-STATE FERMENTATION
ABSTRACT Filamentous fungi can easily degrade agro-industrial wastes in solid-state fermentation processes, synthesizing many important commercial biocompounds, such as lipolytic enzymes. The aim of this study was to evaluate the effect of the composition of the solid culture medium on the production of lipolytic enzymes by the fungus Aspergillus niger. Rice

8. 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

9. Biophysicochemical characterization of Pyocin SA189 produced by Pseudomonas aeruginosa SA189
Abstract Pseudomonas aeruginosa, in spite of being a ubiquitous organism (as it is found in soil, water, and humans), is also an opportunistic pathogen. In order to maintain its diversity in the community, it produces various toxic proteins, known as, bacteriocins. In the present study, pyocin SA189, which is a bacteriocin produced by P. aeruginosa SA189 (is

10. Milk-deteriorating exoenzymes from Pseudomonas fluorescens 041 isolated from refrigerated raw milk
The practice of refrigerating raw milk at the farm has provided a selective advantage for psychrotrophic bacteria that produce heat-stable proteases and lipases causing severe quality problems to the dairy industry. In this work, a protease (AprX) and a lipase (LipM) produced by Pseudomonas fluorescens 041, a highly proteolytic and lipolytic strain isolated

11. Endophytic fungi from medicinal plant Bauhinia forficata: Diversity and biotechnological potential
Bauhinia forficata is native to South America and used with relative success in the folk medicine in Brazil. The diversity, antibacterial activity, and extracellular hydrolytic enzymes of endophytic fungi associated with this plant were studied. Plant samples, which included leaves, sepals, stems, and seeds, were used. Ninety-five endophytic fungal were isol

12. 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
