Background: Zymomonas mobilis, as a novel platform for bio-ethanol production, has been attracted more attention and it is very important to construct vectors for the efficient expression of foreign genes in this bacterium. Results: Three shuttle vectors ( pSUZM 1, pSUZM2 and pSUZM3 ) were first construc...
Histochemical studies of myocardial biopsies from chronic chagasic patients at different evolutive stages showed a pattern primarily characterized by a marked increment in tissue enzymes such as mono-amine oxidase and lysosomal acid phosphatase. This cellular damage can be reflected by changes in certain...
Trichoderma pseudokoningii. Rifai foi isolado como contaminante em experimentos realizados sob nitrogênio líquido. Apresentou atividade amilolítica superior a de outros fungos isolados do solo ou do ambiente. Verificou-se que exuste relaçäo direta entre o crescimento do fundo e a produçäo de amila...
