1. Use of elephant grass (Pennisetum purpureum) as substrate for cellulase and xylanase production in solid-state cultivation by Penicillium echinulatum
Abstract The high cost of the enzymes used for the hydrolysis of lignocellulosic biomass is one of the bottlenecks in the production of second-generation ethanol and the use of local biomass, such elephant grass, can help to reduce this cost. In this investigation elephant grass biomass was evaluated as a carbon and inducer source of production of cellulases

2. Fodder radish cake (Raphanus sativus L.) as an alternative biomass for the production of cellulases and xylanases in solid-state cultivation
Abstract Fodder radish (FR) is an oilseed crop with a high potential for biodiesel production due to its high productivity and the quality of its seed oil. FR oil extraction results in a residue that is rich in protein and fiber. In this study, FR cake (FRC) was evaluated as carbon and nitrogen source for the production of cellulases and xylanases using Peni

3. Potassium biphthalate buffer for pH control to optimize glycosyl hydrolase production in shake flasks using filamentous fungi
Abstract The optimization of culture medium with statistical methods is widely used in filamentous fungi glycosyl hydrolase production. The implementation of such methodology in bioreactors is very expensive as it requires several pH-controlled systems operating in parallel in order to test a large number of culture media components. The objective of this st

4. STATISTICAL OPTIMIZATION OF MINERAL SALT AND UREA CONCENTRATION FOR CELLULASE AND XYLANASE PRODUCTION BY Penicillium echinulatum IN SUBMERGED FERMENTATION
Abstract Penicillium echinulatum S1M29 is a mutant with cellulase and xylanase production comparable to the most studied microorganisms in the literature. However, its potential to produce these enzymes has not been fully investigated. This study aimed at optimizing salt and urea concentrations in the mineral solution, employing the response surface methodol

5. Expressão do complexo celulolítico em Penicillium echinulatum
O Penicillium echinulatum linhagem 9A02S1 é um fungo filamentoso que apresenta um sistema celulolítico com potencial para aplicação em processos de degradação de materiais lignocelulósicos para produção de etanol. O crescente interesse nesse combustível e a abundância de materiais lignocelulósicos que podem ser usados como matéria-prima fez aume

6. Produção de celulases e xilanases por Penicillium echinulatum em processo submerso utilizando biorreatores com agitação mecânica e airlift de circulação interna
Cellulolytic enzymes have many uses, particularly in the food, textile, and paper industries. However, their major potential use is in the hydrolysis of cellulose a component of lignocellulosic residues for ethanol fuel production. Among the cellulase-producing microorganisms, mutants of the Trichoderma genus are the most studied and most widely used in the

7. Clonagem, expressão heteróloga e caracterização funcional de uma endoglicanase de Penicillium echinulatum
This work describes the pioneering molecular biology studies with the fungus Penicillium echinulatum lineage 9A02S1 (DSM 18942), which resulted in the first isolation and characterization of a cDNA corresponding to an egl1 gene, encoding a endoglucanase 1 (EGL1). The egl1 cDNA was obtained from a library constructed under induction conditions of the cellulol

8. Classification of terverticillate penicillia based on profiles of mycotoxins and other secondary metabolites.
Strains of available terverticillate penicillium species and varieties were analyzed for profiles of known mycotoxins and other secondary metabolites produced on Czapek yeast autolysate agar (intracellular metabolites) and yeast extract-sucrose agar (extracellular metabolites) by using simple thin-layer chromatography screening techniques. These strains (2,4
