1. A Novel Colorimetric Immunoassay of Ultrasensitive Alpha-Fetoprotein Sensing in Magnetic Bead-Based Mimic Enzyme-Chromogenic Substrate System
This work described a simple and feasible colorimetric immunoassay. Using hemin (a horseradish peroxidase (HRP) mimic enzyme) and the mimic enzyme-chromogenic substrate system, it can qualitatively and quantitatively detect a-fetoprotein (AFP) at an ultralow concentration. The glucose oxidase (GOx) catalyzed oxidation of glucose leads to the formation of glu

2. Effect of carbon source on production, characterization and bioactivity of exopolysaccharide produced by Phellinus vaninii Ljup
ABSTRACT The effect on different three carbon source (i.e. glucose, fructose and sucrose) on production, chemical characterization and antioxidant activity of exopolysaccharide (EPS) produced by Phellinus vaninii Ljup was investigated in this study. Amongst carbon sources examined, glucose and sucrose were favorable for the mycelia growth, while the maximum

3. Tricalcium phosphate solubilization and nitrogen fixation by newly isolated Aneurinibacillus aneurinilyticus CKMV1 from rhizosphere of Valeriana jatamansi and its growth promotional effect
Abstract Aneurinibacillus aneurinilyticus strain CKMV1 was isolated from rhizosphere of Valeriana jatamansi and possessed multiple plant growth promoting traits like production of phosphate solubilization (260 mg/L), nitrogen fixation (202.91 nmol ethylene mL-1 h-1), indole-3-acetic acid (IAA) (8.1 µg/mL), siderophores (61.60%), HCN (hydrogen cyanide) produ

4. Estudos preliminares de produção de ácido glucônico a partir de sacarose invertida em biorreator airlift
The use of sucrose for the production of industrial inputs with higher added value has a great industrial interest, especially glucose and fructose which present many advantages over sucrose in industrial processes. Gluconic acid and its derived salts can be mentioned as second generation products also having wide industrial applicability. This study aimed t

5. Invertase, glucose oxidase and catalase for converting sucrose to fructose and gluconic acid through batch and membrane-continuous reactors
Neste trabalho estudou-se a conversão da sacarose em frutose e ácido glicônico, usando as enzimas invertase, glicose oxidase e catalase, através do emprego de processo descontínuo (com adição sequencial ou simultânea das enzimas) e contínuo (adição simultânea das enzimas em reator com membrana acoplado à membrana de ultrafiltração de 100 kDa).

6. Conversão multienzimática da sacarose em frutose e ácido glicônico usando reatores descontínuo e contínuo / Multienzyme Conversion of sucrose into fructose and gluconic acid in Discontinuous and Continuous Reactors
A sacarose é uma matéria-prima, cuja produção é considerada ecologicamente correta, sendo o Brasil seu maior produtor e exportador. O dissacarídeo pode ser convertido, através de um processo multienzimático, em substâncias de maior valor agregado: frutose e ácido glicônico, as quais são importadas pelo Brasil, tendo amplo uso nos setores químico

8. HidrÃlise e oxidaÃÃo catalÃtica dos carboidratos do bagaÃo de cana-de-aÃÃcar em operaÃÃes descontÃnuas
In the local context, is clearly meet the need to enhance the sugarcane bagasse as biomass plant. Sugar cane bagasse is a waste coming from alcohol and sugar industries and available abundantly. This availability of sugarcane bagasse as raw material at low cost, combined with the feasibility of its recovery via chemical and biochemical processes, is the foun

9. Study of the interaction of aluminium with gluconic acid / ESTUDO DA INTERAÇÃO DO ALUMÍNIO COM O ÁCIDO GLUCÔNICO
Parenteral solutions are used for patients with complexes diseases, for pre-term infants and surgical patients. The administration of solutions contaminated by aluminium for a long period of time can lead to severe intoxication, with consequent bone and neurological diseases. Considering that, the FDA (Food and Drug Administration) has been investigating the

10. Development of automatic procedures for the determination of 3-hidroxybutyrate, glucose and cholesterol in animal blood serum using in flow multicommutation. / Desenvolvimento de procedimentos automáticos para a determinação de 3-hidroxibutirato, glicose e colesterol em soro de sangue animal empregando multicomutação em fluxo.
In the present work, in flow injection systems were developed for the determination of important metabolic parameters, such as 3-hydroxybutyrate, glucose and cholesterol in animal blood serum. The analysis modules were developed based on the multicommutation concept, whose main characteristics favor the processing of many samples. For this, three-way solenoi

12. Cloning of a mineral phosphate-solubilizing gene from Pseudomonas cepacia.
We have recently shown that the ability of some gram-negative bacteria to dissolve poorly soluble calcium phosphates (Mps+ phenotype) is the result of periplasmic oxidation of glucose to gluconic acid via the quinoprotein glucose dehydrogenase (GDH), a component of the direct oxidation pathway. Escherichia coli K-12 derivatives synthesize apo-GDH but not the
