13. Sucrose metabolizing enzymes in cell suspension cultures of Bauhinia forficata, Curcuma zedoaria and Phaseolus vulgaris.
The objective of this work was to study the activity of sucrose metabolizing enzymes in extracts of cell suspension cultures of Bauhinia forficata Link, Curcuma zedoaria Roscoe and Phaseolus vulgaris L. Invertase pathway was identified in the three studied species. Sucrose synthase pathway was also responsible for sucrose metabolism in Curcuma zedoaria and P

14. Sucrose metabolism during fruit development in coffea racemosa.
Sucrose is one of the compounds in the raw coffee bean that has been identified as an important precursor of coffee flavour and aroma. In order to increase our knowledge of sucrose metabolism in coffee species, sucrose and reducing sugar content were investigated in the fast fruit-ripening coffee species Coffea racemosa. Fruits were harvested regularly from

17. Production of α-Galactosidase by Aspergillus oryzae through solid-state fermentation and its application in soymilk Galactooligosaccharide hydrolysis
α-Galactosidase was produced by Aspergillus oryzae on red gram plant waste-wheat bran based media in solid-state fermentation (SSF). Optimum temperature for α-galactosidase production was 35 0C and upto 4 cm of bed height of substrate had no inhibitory effect on enzyme production. Hydrolysis of galactooligosaccharides in soymilk was carried out by α-galac

19. Fermentação de mosto industrial por linhagens de Saccharomyces cerevisiae com transportador de sacarose e sobreexpressão de invertase interna: estudo comparativo com linhagens com alta e baixa atividade de invertase externa / Fermentation of industrial must by strains of saccharomyces cerevisiae with sucrose transporter and overexpression of internal invertase: a comparative study with strains with high and low activity of external invertase
O presente trabalho teve como objetivo avaliar o perfil de metabolização de açúcares por linhagens de S. cerevisiae amplamente utilizadas no setor sucroalcoleiro (CAT-1 e BG-1) e uma linhagem geneticamente modificada (HCJ 003) com o propósito de sobreexpressar invertase intracelular e ainda contém transportadores de sacarose de alta afinidade. Para tal

20. Otimização da Produção de Enzimas por Aspergillus niger em Fermentação em Estado Sólido
Brazil is one of the main producer countries of rice and passion fruit. The production of these foods have generated a large amount of wastes which could represent serious problems with the final disposal and cause economic losses from misuse of biomass. The enviroment pollution and loss of economic value from this biomass can be reduced by using this materi

21. Metabolismo de carboidratos e de fenóis no armazenamento refrigerado de cenoura / Metabolism of carbohydrates and of phenols in the refrigeration storage of carrot
As raízes de cenoura, quando submetidas ao processamento, sofrem diversos tipos de cortes que promovem alterações físicas, químicas e fisiológicas no tecido. Em razão disso, o primeiro experimento teve como objetivos avaliar os teores de carboidratos e a atividade enzimática em cenouras inteiras e em pedaços armazenadas a 4C. No outro experimento os

23. Produção de açúcar invertido pelo uso de invertase imobilizada em resinas
This work aims to offer a contribution for the development of the production of invert sugar by invertase immobilized on ion exchanging resins. The experiments were conduced in a batch stirred microreactor with temperature control and magnetic agitation. Firstly, kinetic assays on free invertase were conduced aiming to determine the hydrolysis kinetic and th

24. VariaÃÃo sazonal da atividade da rubisco e das enzimas de sÃntese e hidrÃlise da sacarose em plantas de seringueira [Hevea brasiliensis (Willd ex. Adr de Juss.) Muell.-Arg], em Lavras/MG / Seasonal variation of Rubisco and sucrose synthesis and hydrolisys enzymes activities in rubber trees [Hevea brasiliensis (Willd ex. Adr. de Juss.) Muell.-Arg], in Lavras, MG.
The growth of rubber tree cultivation in Brazil has happened because of growing of natural rubber market. With aim to escape of âSouth American leaf blightâ â a common disease in amazonian region â the rubber tree expansion has privileged no traditional regions in Brazil. In Minas Gerais, where rubber tree cultivation is still incipient, new researches a
