Abstract

There are two temperature optima connected with lignin peroxidase synthesis by Phanerochaete chrysosporium INA-12. One, at 37 degrees C, is for the mycelium-growing phase; the other, at 30 degrees C, is for the lignin peroxidase-producing phase. One of six extracellular proteins with ligninase activity increased when cultures were grown at 30 degrees C for the entire fermentation period or when cultures were grown at 37 degrees C for the first 2 days of incubation and then shifted to 30 degrees C, compared with the activity of control cultures grown at 37 degrees C for the entire fermentation period. The unsaturation of fatty acid (Delta/mole) of P. chrysosporium INA-12 mycelium decreased from 1.25 to 1.03 when the growth temperature was shifted from 20 to 40 degrees C.
