Polystictus versicolor

The enzyme properties reported above are similar to those of an aromatic alcohol oxidase from Polystictus versicolor (27). However, the latter enzyme had a different substrate specificity and the cultures did not produce laccase.

The simple indole alkaloids harman (27) and harmine (28) are also susceptible to biotransformation. Polystictus versicolor metabolizes both 27 and 28 to unidentified products, formed in a yield of 50% in the case of 28 (42). Mammalian liver preparations perform an oxidative O-demethylation of harmine (28) to produce harmol (29) (45). The supernatant fraction from the lO.OOOg centrifugation of liver homogenates of cow, mouse, rabbit, guinea pig, rat, and cat were all effective in O-demethylation, the highest yields (90%) being obtained after incubation for 30 min with the preparations from cow and mouse liver (45). No other products were detected from the biotransformation of harmine by the liver preparations mentioned above,... 

Nocardia restrictus is capable of oxidizing the conessine derivative 5a-conanin-3/i-ol (220) to both the A4-3-ketone 222 and the A1,4-3-ketone 221, the latter being the major product of the incubation (189). Preliminary screening experiments have demonstrated that Trichothecium rosevan transforms conessine (223), solanocapsine (224), jervine (225), and pseudojervine (226) (42). Transformation of the latter is claimed to produce 20-30% jervine by glycoside hydrolysis, along with an unidentified product that may be further biotransformation product of jervine. Jervine is also metabolized by Polystictus versicolor and Piricularia oryzae, but no products have been identified (42). 

A pOi electrode was frequently employed for the measurement of oxygen concentration in bacterial cultures e.g. [68-70]. With the same method May and Jacob [71] measured continuously the respiration activity of mitochondria fractions from Polystictus versicolor. The respiration of various cells (e.g., lymphocytes, macrophages) was studied [72].

The biborate is used in solvent based wood preservatives. It is also effective on white rots such as Polystictus versicolor.
