Decolorization and degradation of xanthene dyes by a white rot fungus, Coriolus versicolor.

The decolorization of six xanthene dyes (conc. 100 microM) by a white rot fungus, Coriolus versicolor (C. versicolor), was investigated in liquid culture.

Comparative study on the biological properties of 2',5'-oligoadenylate derivatives with purified human RNase L expressed in E. coli.

An endoribonuclease, RNase L, which is activated in the presence of 2',5'-linked oligoadenylates, p(1-3)A(2'p5'A)(>2), is the terminal factor of the anti-viral action of interferon. Activation of RNase L results in inhibition of viral proliferation along with induction of apoptosis. Attempts to acquire more effective activators, 2-5A derivatives, have been made for the development of antiviral or anticancer agents.

Decolorization of methyl red by a mixed culture of Bacillus sp. and Pseudomonas stutzeri.

The decolorization of methyl red directed toward rapid reduction of azo group by a mixed culture of Bacillus sp. and Pseudomonas stutzeri was investigated. The improvement of the decolorization of methyl red was obtained by a mixed culture (a mixed culture 2) with particular proportion of two bacteria (Bacillus sp.
