查询词典 microbial

In this research work, the technology of microbial conversion was studied in order to establish an environment friendly method for the production of doxorubicin. A doxA gene encoding Daunorubicin C-14 hydroxylase was cloned from a daunorubicin-producing strain Streptomyces coeruleorubidus SIPI 1482. Some plasmids for the expression of doxA gene were constructed and transformed into S.

However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.
