✦ Synopsis

Cometabolic growth studies with phenol were undertaken to screen 32 strains of white and brown rot fungi. All the cultures studied grew well up to 4 mM of phenol on CZAPEKDOX agar except Agaricus bisporus (white button mushroom) and Pleurotus cystidiosus. Most of them could grow even up to 6mM of phenol. Phenol induced a brown pigmentation of the culture medium. P.jlabel1atus and P . pulmonarius metabolized 67 and 64 mg/l phenol in 10 days. Studies have indicated that phenol (0.1 to 1.0 mM) incorporated in malt-extract agar has no inhibitory effect on fruitbody formation. Preliminary studies indicate that soaking of wheat straw with phenol solution up to 1600 mg/l give better mycelial growth and fructification of P . cornucopiae, P. ostreatus Z-15 and Calocybe indica than water soaked. Soaking of wheat straw in phenol inhibited the growth of common competitor weed fungi 4ke Stachybotrys sp. and Coprinus sp.
