Time course of cellulolytic enzyme activities by P. oxalicum. a–e Under original production medium (solid squares), cow manure (solid circles), anaerobically digested cow manure (triangles). Data presented are average of triplicate experiments; error bars indicate the standard deviations. f SDS-PAGE of proteins from unconcentrated culture supernatants of P. oxalicum C1-9 when cultured in cow manure medium (lane 2) and anaerobically digested cow manure medium (lane 3) as compared original production medium (lane 1) inducing cellulase expression for 96 h
