Notes-Microbiological Transformation of Steroids. IX. The Transformation of Reichstein's Compound S by Scenedesmus sp. Diketopiperazine Metabolites from Scenedesmus sp.

Diketopiperazines from the Marine Sponge Axinella sp.

“…podatypa [17], and sponge-associated microorganisms Alcaligenes faecalis A72 [18], the phytopathogenic fungus Rhizoctonia solani [19], marine bacteria Pecten maximus [8], Ceratocystis species [20], Aspergillus ochraceus and Oopsra destructor [21], sponge-associated bacterium Pseudomonas aeruginosa [22], Scenedesmus sp. [23], and roasted cocoa nibs [11]. Compound 4 found in these microorganisms indicated that it may be produced by the symbiotic microorganisms associated with the sponge Axinella sp.…”

Progesterone biotransformation by plant cell suspension cultures

“…Such a high yield with a relative absence of by-products is reminiscent of the conversions obtained with the yeast Rhodotorula longissima (4). The 20a reduction has been reported to be carried out by yeasts (3), algae (17), plants (16), and mice (25), but not by bacteria or molds. The cultures of L.…”
