Pigmented bacteriostatic substances and amino acids produced by Phlebopus sulphureus and Phlebopus lignicola.
The pigmented bacteriostatic substances and ninhydrin-reactive compounds produced in culture by sporophores, stipes, and residual medium of Phlebopus sulphureus and P. lignicola were studied chromatographically. Acetone extracts of both species demonstrated bacteriostatic activity against Bacillus subtilis and Escherichia coli, the maximal inhibition zone being 13 mm. The chloroform extract was inactive. Six compounds, mainly yellow, extracted in ethyl alcohol and separated by chromatography, were common to the sporophore of P. sulphureus and the stipes of P. lignicola. Eight amino acids, mainly sulfur-containing, were identified chiefly from the mature sporophore of P. sulphureus.
