The mycelia of Streptomyces, Mucor rouxii, Phycomyces blakesleeanus, and Choanephora cucurbitarum, after treatment either with 40% NaOH at 100/sup 0/C for 3-4 h or 0.01 M NaOH for 60 min, were studied by IR spectrometry, to assess their chitin and chitosan contents, and used to collect Cr, Mn, Co, Ni, Cu, Zn, Hg, and Pb from 0.5 mM solutions at 20 and 60/sup 0/C. The results reflect the chelating ability of chitosan and are especially high for the Streptomyces inactivated material, which is available in large amounts as a waste of industrial fermentations.
