Abstract

|
|
|
Four ectomycorrhizal fungi were tested for their ability to utilize seven carbon sources in modified Melin-Norkrans medium. After 60 days of mycelial culture, the highest mycelial growth in (KFRI 1987), , (KFRI 1194), and (KFRI 1256) was observed with use of dextrin used as a carbon source. , (KFRI 1676), and showed the lowest mycelial growth on nutrient medium with pectin. The utilization of homoglycans (starch, dextrin) in seven strains (except for KFRI 1256) was higher than that of heteroglycan (pectin). The final pH values of all culture media were decreased by pH 1.1~3.0 compared with the initial pH values of culture media. The dominant color of mycelia was white and varied according to the carbon sources (yellow, brown, and purple) in some strains. A single colony was observed in cultured in liquid media containing four or five different types of carbon sources, whereas multiple colonies were formed in liquid media containing six different types of carbon sources by six strains.
