| decolorization of anthraquinone dye with immobilized penicillium jensenii. | cells of penicillium jensenii were immobilized by entrapment in natural and synthetic polymeric matrices. the decolorization of reactive brilliant blue kn-r by immobilized cells has been studied. it was found that ca-immobilized cells could effectively decolorize reactive brilliant blue kn-r. many factors affecting the decolorization process were studied, including: ph, temperature, dye concentration, shaker speed and culture time. the reusability of the immobilized cells was evaluated with repe ... | 2005 | 16334285 |
| fr65814, a novel immunosuppressant isolated from a penicillium strain. taxonomy, fermentation, isolation, physico-chemical and biological characteristics and structure assignment. | fr65814, a novel immunosuppressant, was isolated from the cultured broth of penicillium jensenii f-2883. the structure was assigned to be 5,6-dihydroxy-4-(1,2-epoxy-1,5-dimethyl-4-hexenyl)-1-oxaspiro++ +[2,5]octane by spectroscopic analyses. the compound suppressed the immune response at low concentration. in addition, a structually related component fumagillol, a known carcinolytic agent, was also isolated and found to show immunosuppressive activity. | 1988 | 3170352 |
