A novel testosterone catabolic pathway in bacteria.

abstract：:Variations of the membrane filter technique for deoxyribonucleic acid (DNA) hybridizations were studied with respect to Streptomyces species. At the temperatures required for specific hybridization of DNA with the high melting temperature (T(m)) characteristic of Streptomyces, large amounts (up to 97%) of filter-bound...
