The cell surface of Penicillium sp. O-7W grown in a glucose-salt medium containing lignosulfonate as a sole source of sulfur showed a rangged structure. On the other hand, mycelia grown in a medium containing sodium sulfate was smooth. This raggedness disappeared when the mycelia were washed with a dilute alkaline buffer (over pH 9.0). The resultant alkaline filtrate had almost the same IR spectrum as that of lignosulfonate added to the medium except for peaks based on sulfonate residue. The sulfur contents of these samples were 2.35% and 4.96%, respectively. Strain O-7W used α-sulfophenyl acetate, taurine, methionine, and p-nitrophenyl sulfate as a sulfur source as well as ligno-sulfonate. Penicillum simplicissimum and Penicillium janthinellium could also grow on the lignosulfonate medium and remove lignosulfonate form the medium during cultivation.
