P. S. GREWAL AND P. HAND. 1992. The effects of 10 species of bacteria isolated from a saprophagous rhabditid nematode Caenorhabditis elegans on mycelial growth of the cultivated mushroom Agaricus bisporus were studied in agar cultures. Bacterial species showed differential effects on the mycelial growth of A. bisporus and the effects also depended upon the mushroom strain (C43, C54 and U3). Bacillus cereus, Bacillus sp. and Enterobacter amnigenus caused significant inhibition in mycelial growth of all three strains of A. bisporus. Pseudomonas aeruginosa, Ps. fluorescens biovar reactans and Ps. maltophilia resulted in a significant increase in mycelial growth of C54 strain. Enterobacter cloacae caused a mean inhibition of about 83% in the linear mycelial extension of the most commonly cultivated mushroom strain U3. Bacillus cereus, Ent. amnigenus and Ent. cloacae produced volatile inhibitory substance(s). This is believed to be the first report about the inhibitory effects of specific bacteria isolated from a saprophagous nematode on the mycelial growth of A. bisporus.
