The uptake of heavy metals at sublethal concentrations by the mycelia and sporocarps of an edible fungus Pleurotus sajor-caju was measured by an atomic absorption spectrophotometer, and their impact on growth, productivity, and cellular proteins was also studied. Mycelia demonstrated the lowest uptake of Co2+ (11 micrograms ml-1) and Hg2+ (12 micrograms(More)
Fungitoxic substance was isolated from the culture filtrate of B. megaterium (B-23). Age of culture and pH of medium influence the fungitoxicity of its culture filtrate. Partially purified toxin was thermolabile, non-dialysable, ethyl acetate soluble, vanillin-sulphuric acid positive and effective within a range of pH 5-9. It exhibited maximum UV absorption(More)
