1. Utilization of residue from cassava starch processing for production of fermentable sugar by enzymatic hydrolysis
Abstract The aim of this study was to characterize and perform enzymatic hydrolysis of cassava peeling residue (peel and inner peel), mainly composed of peels and small pieces. Residue was sanitized, dried at 55 °C for 24 hours and ground. The obtained flour showed pH of 4.85; 72.53 g 100 g–1 moisture; 5.18 mL 1M NaOH 100 g–1 acidity; 60.68 g 100 g–1

2. OTIMIZAÇÃO DO PROCESSO DE SACARIFICAÇÃO DO AMIDO DE BATATA (Solanum Tuberosaum L.) UTILIZANDO ENZIMAS AMILOLÍTICAS / OPTIMIZATION OF THE SACCHARIFICATION OF POTATO STARCH (Solanum Tuberosaum L.) USING AMYLOLYTIC ENZYMES
A batata (Solanum tuberosum) é importante matéria-prima agroindustrial para produção de hidrolisados. A falta de informações sobre o processo de hidrólise do amido de batata na indústria dificulta a utilização desta matéria-prima regional e favorece o uso das culturas como: milho, mandioca e cana de açúcar para produção de álcool etílico. O

3. Modificação enzimática da farinha de arroz visando a produção de amido resistente
The aim of this work was to study the enzymatic modification on rice flour using lipase pancreatic and amyloglucosidase to obtain resistant starch. For this, Response Surface Methodology (RSM) was used to determine the best operating conditions for each enzyme. For lypase pancreatic, the highest value for resistant starch (45%) was achieved within 2 h reacti

4. Adsorption of amyloglucosidase from Aspergillus niger NRRL 3122 using ion exchange resin
A enzima amiloglicosidase foi produzida por Aspergillus niger NRRL 3122 através de fermentação em estado sólido, tendo como substrato farelo de arroz desengordurado. Os efeitos dos parâmetros de processo (pH e temperatura) no coeficiente de partição no equilíbrio, para o sistema amiloglicosidase - resina DEAE-celulose foram investigados, com o objeti

5. Simultaneous amyloglucosidase and exo-polygalacturonase production by Aspergillus niger using solid-state fermentation
As enzimas amiloglicosidase (AMG) e exo-poligalacturonase (exo-PG) foram produzidas simultaneamente por duas cepas de Aspergillus niger, através de fermentação em estado sólido usando farelo de arroz desengordurado como substrato. Foram avaliados os efeitos da cepa de Aspergillus niger, tipo de inóculo e adição de indutores no meio de cultura, utiliza

6. Desenvolvimento de pão de forma sem adição de açucares, gorduras e emulsificantes, com o uso de enzimas e amido de mandioca modificado. / No sugar, fat and emulsifier bread development using enzymes and tapioca modified starch.
Modern societies are presenting a growing interest in healthy foods, low calories and free from undesirable ingredients such as sugar, saturated and "trans" fatty acids but maintaining sensorial characteristics of the original foods. This work intends to present an option of sliced bread with total substitution of sugar, fat and emulsifiers, with the use of

7. Papel da trealose no metabolismo de larvas de Pyrearinus termitilluminas (coleoptera: elateridae) sob estresse hídrico / The role o trehalose in the metabolism of Pyresrinus termitilluminas larvae (coleoptera: elateridae) under hidric stress
The life cycle of Pyrearinus termitilluminans (Coleoptera: Elateridae) takes place totally into the so-called luminous termite mounds located in Central Brazil, which are clearly observed during the rainy season. Light emission by the elaterid larvae acts like a trap attracting flying insects. The bioluminescence disappears in the dry months together with th

8. Preparation of silica with controlled pore sizes for enzyme immobilization
A simple method for the preparation of silica with controlled pore size, for use as a support for the immobilization of enzymes, is described in this article. Using sodium silicate and hydrochloric acid, a microporous silica was obtained that was then submitted to a hydrothermal treatment, resulting in macroporous silica suitable for enzyme immobilization. S

9. Estudo da produção de amiloglicosidase por Aspergillus Niger NRRL 3122 em fermentação semi solida de farelo de arroz
This is an experimental study of solid-state fermentation(SSF) of rice bran to produce amyloglucosidase (E.C. 3.2.1.3.) by Aspergillus niger NRRL 3122. The research was conducted in 4 phases: optimization of physico-chemical parameters; SSF in fixed-bed column reactors; characterization of enzyme kinetics; determination of thermal conductivity.

10. Contribuição para o estudo da linhagem Neurospora sp isolada de beiju de mandioca
Several strains of Neurospora sp were isolated from beiju which is used for production of tiquira in various regions of the state of Maranhão. All isolated strains, including Nelfrospora sitophila ATCC 46892 wich was also isolated from beiju by Park et alii in 1982 have produced fruity aroma that was identified as ethy hexanoate. In this research was studie

12. Isolamento e analise genetica de mutantes de Aspergillus niger com aumento na produção de amiloglicosidase
The aim of this work was the isolation and genetical analysis of mutants with increased amyloglucosidase production using the pab1fwn1 strain of Aspergillus Niger. The mutagenic used was ultraviolet light that showed efficiency in the induction of this type of mutant, which could be isolated after some modifications in the methodology used by VALENT (1985).
