A procedure for feasible and optimal operational strategies for control of CARE systems
(Wiley-blackwellMaldenEUA, 1997)
Produção de proteases por bacillus sp. sob cultivo submerso na presença de resíduos agroindustriais
(Universidade Católica de Pernambuco, 2012-09-04)
The reuse of agro-industrial waste as sources of carbon and nitrogen has been investigated in biotechnology for the production of enzymes by microorganisms. Among the microbial enzymes imported into Brazil, the proteases ...
Reactions of All Escherichia coli Lytic Transglycosylases with Bacterial Cell Wall
(American Chemical Society, 2013-02)
The reactions of all seven Escherichia coli lytic transglycosylases with purified bacterial sacculus are characterized in a quantitative manner. These reactions, which initiate recycling of the bacterial cell wall, exhibit ...
Ascorbic acid metabolism in fruits: activity of enzymes involved in synthesis and degradation during ripening in mango and guava
(JOHN WILEY & SONS LTD, 2008)
BACKGROUND: Ascorbic acid is a very important compound for plants. It has essential functions, mainly as an antioxidant and growth regulator. Ascorbic acid biosynthesis has been extensively studied, but studies in fruits ...
Saccharification of acid–alkali pretreated sugarcane bagasse using immobilized enzymes from Phomopsis stipata
(2022-01-01)
In this study, a mild-temperature two-step dilute acid and alkaline pretreatment (DA-AL) process was developed to generate highly digestible cellulose pulp from sugarcane bagasse for producing fermentable sugars by novel ...
Produção de celulases e xilanases por fermentação em estado sólido usando palha de carnaúba pré-tratada e avaliação da reutilização do resíduo
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2017-11-06)
Native to Brazil, the Carnaúba palm (Copernicia prunifera) has been used in the production of wax from its leaf. After extraction of the wax, a considerable amount cellulose-rich fibers is generated which can be used as a ...
Immobilization of enzymes of agroindustrial interest on hydroxyapatite nanoparticles: β-glucosidase, xylase and phytase
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2020-03-10)
Industrial processes are increasingly requiring environmentally sustainable technologies and the use of enzymes is relevant due to the selectivity and specificity of these biocatalysts. However, the application of soluble ...
