1. Inhibitory effects of L-3-phenyllacitc acid on the activity of mushnroom pholyphenol oxidase
Abstract Polyphenol oxidase is the popular enzyme involved in fruit-vegetable browning and melanin synthesis. In the present paper, L-3-phenyllactic acid, a natural bacteriostatic substance, was investigated as an inhibitor of polyphenol oxidase. The results were demonstrated that the residual enzyme activity of polyphenol oxidase decreased gradually with th

2. MICROWAVE ACTIVATION OF IMMOBILIZED LIPASE FOR TRANSESTERIFICATION OF VEGETABLE OILS
This work investigated the effect of microwave irradiation (MW) on the ethanolysis rate of soybean and sunflower oils catalyzed by supported Novozyme 435 (Candida antarctica). The effects of tert-butanol, water addition and oil:ethanol molar ratio on transesterification were evaluated under conventional heating (CH), and under optimum reaction conditions (wi

3. A new enzymatic process for the treatment of phenolic pollutants
This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o) and enzyme (C T) concentrations as independent variables. Experimental data of the residual phenol concentration (C P) were used to calculate the ox

4. Produção, caracterização bioquímica e purificação de fitase produzida por Aspergillus niger var. phoenicis URM 4924.
During ripening, vegetable seeds and grain accumulated substantial amount of phytic acid, representing over 60% of total phosphorus in them. Phytate acts as an energy source for seed germination and is rarely available for non-ruminants, since they do not synthesize the enzyme. Due to the unavailability of biological organic phosphorus in many vegetable food

5. Evaluation of enzymatic potential of filamentous fungi isolated from different sources / AvaliaÃÃo do potencial enzimÃtico de fungos filamentosos isolados de diferentes fontes
Enzymes are protein macromolecules responsible for the acceleration of the chemical reactions that maintain and regulate living organisms. They occur in nature and can be from vegetable, animal and microbial sources. Due to high industrial demand the microbial sources are the most used. The filamentous fungi compose the group of microorganisms with highest n

6. Síntese de biodiesel através de transesterificação enzimática de óleos vegetais catalisada por lipase imobilizada por ligação covalente multipontual
Biodiesel consiste de ésteres alquílicos de ácidos graxos produzidos pela transesterificação de triglicerídeos com álcoois de cadeia curta. Tradicionalmente, a reação ocorre na presença de catalisadores químicos, como álcalis ou ácidos. A utilização alternativa de lipases como biocatalisadores na reação de síntese do biodiesel não gera mat

7. Different threonine: lysine relations in chicks cutting diets supplemented with glycine: enzymatic activity and performance / Diferentes relações treonina: lisina em dietas para pintos de corte, suplementadas com glicina: desempenho e atividade enzimática
Two experiments were conducted, one for performance and another for metabolism, with objectives of evaluating the effect of different digestible threonine: digestible lysine relations, supplemented or not with glycine on the performance, the threonine aldolase, threonine dehydrogenase and threonine dehydratase enzyme activity and the uric acid excretion of c

8. Caracterização e purificação da enzima bromelina em sistema de duas fases aquosas PEG/Fosfato / Bromelain enzyme caracterization and purification using two aqueous phases system PEG/Phosphate
The bromelains are proteases from vegetable origin, obtained from several species of Bromeliaceae family, which are found in pineapple s stem and fruit. The bromelains uses are based on its proteolytic activity on food industries and mostly at Brazilian pharmaceutical industry. The bromelains has been documented by its therapeutic effects at all inflammatory

9. EletroquÃmica acoplada à ressonÃncia de plÃsmons de superfÃcie no estudo de adsorÃÃo de proteÃna em filme fino
Biosensor is a device in which the biological source material, such as enzyme, organelle, animal or vegetable tissue, microorganism, antigen or antibody, nucleic acids, lectina, among others is immobilized close to an adequate transducer. Therefore, the electrode/biomolecule/ solution interface characterization consists in one of the main stages for biosenso

10. Pectinases produced by the biological agent G088: extraction and purification / Pectinases produzidas pelo agente biolÃgico G088: extraÃÃo e purificaÃÃo
The pectinases are responsible for the degradation of a complex molecule of pectina which are present in every young vegetable organ. The production of pectinases in microorganisms is influenced by the culture time and the appropriate choice of ancestry. Considering the current high use of enzymes from microorganisms nowadays, different procedures for isolat

11. Efeito inibitÃrio do extrato aquoso do guaranÃ, do chà verde e da epigalocatecina-3 galato sobre a atividade da enzima que degrada a insulina em prÃstata de rato
Insulin degrading enzyme (IDE) is an intracellular protein that degrades insulin and others peptides and hormones. Insulin degradation is important both in the control of cellular responses to the hormone and in the interaction of the hormone with their target tissues. Multiple cellular functions are related to the IDE in addition to degradation, including b

12. Estudo da recuperação da enzima G6PDH, em colunas de campanulas pulsantes, com o uso de micelas reversas / Studies of recovery of G6PDH enzyme, in pulsed caps columns, using reversed micelles
The enzime glucose-6-phosphate dehydrogenase (G6PDH) it can be obtained of animal origin, vegetable or microbial, as in the case of the yeast Saccharomyces cerevisiae. This enzymes presents great importance for the cellular survival once it participates in the regulation of the cycle of the pentosys being responsible for the support of an appropriate level o
