Abstract: | Mycelial growth of an isolate ofT. bakamatsutake was tested in media with C/N ratio ranging from 0 to 50 and with 32 carbon and 12 nitrogen sources. The isolate grew best
at the C/N ratio of 30. It utilized the monosaccharidesd-glucose,d-mannose, andd-fructose, the disaccharide trehalose, and polysaccharide pectin among the carbon sources; and yeast extract,l-glutamic acid, and ammonium compounds among the nitrogen sources. The growth of ten isolates and secretion of gluconic and
oxalic acids were compared ind-glucose, trehalose, and pectin media. The utilization ofd-glucose, trehalose, and pectin differed among the ten isolates, but all the isolates secreted gluconic acid in thed-glucose media and oxalic acid in the pectin media. |
