本文描述北臺灣山區土壤所分離之臺灣新紀錄種Williopsis saturnus和Zygowilliopsis californica。所有試驗菌株之生理型態皆各具其典型之Williopsis saturnus或Zygowilliopsis californica特徵,且其核糖體D1/D2序列與此兩菌種及所屬變種之標準菌株,其序列僅有一個核苷酸以下的差異。本文描述此兩臺灣新紀錄種之生理與型態特徵。
Strains identified as Williopsis saturnus or Zygowilliopsis californica were isolated from soil in northern Taiwan and are new records to Taiwan. All the strains examined had typical morphological and physiological characteristics to W. saturnus or Z. californica, respectively. Meanwhile, their sequences of D1/D2 domain of large subunit rDNA were closely related to those of these two strains (0 or 1 nucleotide difference), respectively. Morphological and physiological characteristics of the strains representing these two species are described.
