Metagenomics is the genomic analysis of the collective genomes of an assemblage of organisms, or the metagenome. Metagenomic analysis has been applied to diverse problems in microbiology and has yielded insight into the physiology of uncultured organisms to access the potentially useful enzymes and secondary metabolites they produce. DNA isolation methods have to be strictly adapted to the type of...
W artykule przedstawiono wybrane metody biotechnologiczne, mikrobiologiczne i enzymatyczne, degradacji odpadowych tłuszczów zwierzęcych i roślinnych. Szczególną uwagę zwrócono na wyniki badań własnych zmierzających do opracowania technologii zagospodarowania odpadowego łoju wołowego i tłuszczu drobiowego. Zaprezentowano m.in. możliwości biokonwersji mikrobiologicznej tych substratów oraz warunki prowadzenia...
Ethanol fermentation of lactose mash by biocatalyzers immobilized in calcium alginate was studied in order to improve the process productivity and economy. The fermentation effectiveness of S. cerevisiae co-immobilized with a ß-galactosidase and the directly lactose-fermenting immobilized yeast: K. fragilis and C. pseudotropicalis were compared. The application of the immobilized K. fragilis produced...
