Última Sugar-cane juice induces pectin lyase and polygalacturonase in Penicillium griseoroseum 59 Minussi,Rosana Cristina; Soares-Ramos,Juliana Rocha Lopes; Coelho,Jorge Luiz Cavalcante; Silva,Daison Olzany. The use of other inducers as substitutes for pectin was studied aiming to reduce the production costs of pectic enzymes. The effects of sugar-cane juice on the production of pectin lyase (PL) and polygalacturonase (PG) by Penicillium griseoroseum were investigated. The fungus was cultured in a mineral medium (pH 6.3) in a rotary shaker (150 rpm) for 48 h at 25oC. Culture media were supplemented with yeast extract and sucrose or sugar-cane juice. Sugar-cane juice added singly to the medium promoted higher PL activity and mycelial dry weight when compared to pectin and the use of sugar-cane juice and yeast extract yielded levels of PG activity that were similar to those obtained with sucrose-yeast extract or pectin. The results indicated that, even at low... Tipo: Info:eu-repo/semantics/article Palavras-chave: Pectin lyase; Polygalacturonase; Pectinases; Penicillium griseoroseum; Sugar-cane juice.

Penicillium griseoroseum was grown in bioreactors on mineral medium supplemented with yeast extract and sucrose. The influence of inoculum and carbon source concentrations, aeration and pH on pectin lyase (PL) production, as well as the capacity of P. griseoroseum to produce PL when grown on sugar cane syrup as carbon source were evaluated. Inoculum concentration did not influence PL production. Production was higher in non-aerated than in aerated medium. The best results were obtained using 60 mM sucrose at pH 6.3-7.2. Production using cane syrup 25% (v/v), without yeast extract supplement, was equal to that obtained under the conditions cited above.

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822001000200013 Fermentation of sweet whey by recombinant Escherichia coli K011 58 Leite,Amarildo Ricardo; Guimarães,Walter Vieira; Araújo,Elza Fernandes de; Silva,Daison Olzany. The production of ethanol from sweet whey using the recombinant Escherichia coli KO11, in batch fermentation, was tested. The maximum ethanol yield was reached after 96h, representing only 38% of the theoretical yield. The supplementation of whey with components of LB broth increased the maximum yield to 96% in 72h. The addition of 0.5% yeast extract to whey resulted in maximum yield of 74% at 36h and it increased to over 100% when yeast extract and trace metals solution (Fe++, Mn++ and Zn++) were added.
