1. SELEÇÃO DE ESPÉCIES DO GÊNERO Penicillium PRODUTORAS DE LIPASE LIGADA AO MICÉLIO PARA APLICAÇÃO EM HIDRÓLISE DE ÓLEOS VEGETAIS
Ten species of Penicillium genus isolated from different habitats were evaluated as mycelium bound lipase producers to be used in the hydrolysis of vegetable oils. Using olive oil as an inducer three species (P. italicum AT4421, P. janthinellum CCT3162 and P. purpurogenum AT2008) were able to produce lipases having high mycelium bound activities (>150 U g-1)

2. Enhanced extraction of phenolic compounds from coffee industry’s residues through solid state fermentation by Penicillium purpurogenum
Abstract The use of agroindustrial residues is an economical solution to industrial biotechnology. Coffee husk and pulp are abounding residues from coffee industry which can be used as substrates in solid state fermentation process, thus allowing a liberation and increase in the phenolic compound content with high added value. By employing statistical design

3. Improvement of submerged culture conditions to produce colorants by Penicillium purpurogenum
Safety issues related to the employment of synthetic colorants in different industrial segments have increased the interest in the production of colorants from natural sources, such as microorganisms. Improved cultivation technologies have allowed the use of microorganisms as an alternative source of natural colorants. The objective of this work was to evalu

4. Thermostable saccharogenic amylase produced under submerged fermentation by filamentous fungus Penicillium purpurogenum
The effect of several nutritional and environmental parameters on Penicillium purpurogenum growth and sacharogenic amylase production was analyzed. High enzyme levels (68.2 U mg-1) were obtained with Khanna medium at initial pH 6.0, incubated at 30ºC for 144 hours. The optimum pH and temperature activities were 5.0 and 65ºC, respectively. The enzyme presen

5. LixiviaÃÃo, formaÃÃo de resÃduos ligados e biorremediaÃÃo de atrazina em solo subtropical submetido à aplicaÃÃo de Ãgua residuÃria da suinocultura / Leaching, bound residues formation and bioremediation of the atrazine in subtropical soil submitted of swine wastewater application
Atrazine is a triazine herbicide, widely used in agriculture to control weeds in corn and cane sugar farming. However, atrazine is considered a pesticide moderately persistent in the environment and the application of wastewater to the soil can affect its environmental performance. In this study, the effects of wastewater from swine (ARS) in leaching, dissip

6. Efeito da adição de substrato sobre a produção de frutosiltransferase pelo Penicillium purpurogenum
Penicillium purpurogenum foi identificado como produtor extracellular e intracelular de frutosiltransferase. O microrganismo também é capaz de produzir uma enzima hidrolítica de sacarose. Sacarose foi identificada como a melhor fonte de carbono para a produção de frutosiltransferase. A produção máxima de frutosiltransferase extracelular e intracelula

7. Produção de ß-glucosidase por Penicillium purpurogenum
Verificou-se que Penicillium purpurogenum foi capaz de produzir ß-glucosidase intracelular, com atividade máxima sobre a sacarose. Vários parâmetros culturais para produção da enzima foram otimizados. Verificou-se que a produção máxima da enzima ocorria após 96 h de cultivo a 30º;C. A adição dos amino-ácidos histidina e cisteína induziram a s�

8. CaracterizaÃÃo quanto a fatores de patogeniciade de fungos filamentosos isolados da praia de candeias, JaboatÃo dos Guararapes, PE.
Os fungos compreendem um grupo de microrganismos saprÃbios, cosmopolitas ou simbiontes importantes componentes dos ecossistemas, constituindo o maior grupo de microrganismo responsÃvel pela produÃÃo de enzimas. Considerando a escassez de trabalhos que tratam da micota filamentosa em ambientes marinhos, este trabalho teve como objetivos isolar, identifica

9. Citrininotoxigenicidade de Penicillium sp. isolado de maçãs deterioradas
Nesse estudo, foi examinada a ocorrência de citrinina e a capacidade de produção do citrinina por cepas de Penicillum spp. isoladas de maçãs deterioradas, recolhidas em pomares domésticos no território da Croácia. De 100 amostras de maçãs examinadas, foram isoladas 37 cepas de Penicillium spp. incluindo P. expansum, P. roqueforti, P. impicatum e P.

10. Production of Rubratoxin B by Penicillium purpurogenum Stoll
Culture filtrates and chloroform extracts from Penicillium purpurogenum isolated from foodstuffs were subjected to preliminary survey for toxic effects on HeLa cells and mice. The toxic metabolite was isolated in a crystalline form from P. purpurogenum and was identified as rubratoxin B. Pathological findings observed in HeLa cells and mice treated with the

11. Induction of Cellulase by Gentiobiose and Its Sulfur-Containing Analog in Penicillium purpurogenum
Cellulase induction by β-glucodisaccharides was investigated by using non-cellulase-induced mycelia of Penicillium purpurogenum P-26, a highly-cellulase-producing fungus. Gentiobiose induced significant amounts of cellulase compared with cellobiose when nojirimycin was added to the induction medium to inhibit extracellular β-glucosidase activity. Thiogenti

12. Cloning and High-Level Expression of α-Galactosidase cDNA from Penicillium purpurogenum
The cDNA coding for Penicillium purpurogenum α-galactosidase (αGal) was cloned and sequenced. The deduced amino acid sequence of the α-Gal cDNA showed that the mature enzyme consisted of 419 amino acid residues with a molecular mass of 46,334 Da. The derived amino acid sequence of the enzyme showed similarity to eukaryotic αGals from plants, animals, yea
