Abstract
|
|
|
|
Button mushroom () strains from diverse origins were compared in this study to obtain basic information on their growth and biochemical properties that are helpful for breeding. Among 31 dikaryotic strains tested, most strains showed better mycelial growth on oatmeal agar than on MEA and PDA. Mycelia of the mushroom strains revealed β-glucosidase activity the most clearly among the seven extracellular enzymes tested. All the strains showed protease activity, but β-glucosidase activity was found in 27 strains and xylanase activity was found in 30 strains. The activity of avicelase, CM-cellulase, amylase, and pectinase was detected in less than 20 strains. These results implied that enzymatic characteristics could be used as a criterion of strain selection for breeding study.
