Abstract
The effect of concentration of carbon and nitrogen sources on the sporulation and the life cycles of three strains of Zygosaccharomyces was investigated. The results are as follows: 1) The good sporulation of Zygosaccharomyces bisporus, delbruekii, and Z. steineri was obtained on solid medium containing 0 to 0.001% of nitrogen and 10 to 20% of glucose. The high content of nitrogen was detrimental to sporulation and asci were formed under 0.01% of nitrogen. 2) It is widely accepted that the life cycle of Zygosaccharomyces proceeds in the following way: Ascospore...Vegetative cells...Conjugation of vegetative cells...Sporulation...Ascopores But zygotes of Z. bisporus proceeded to vegetative cells when transfered to the suitable medium for vegetative reproduction, and then formed asci.
C 원(源)과 N 원(源)으로써 glucose와 casamino acid를 사용(使用)하여 당농도(糖濃度)와 N 농도(濃度)의 차이(差異)가 Zygosacch. bisporus, Zygosacch. debrueckii, Zygosacch. steiner: 의 포자형성(胞子形成) 및 증식(增殖)과 life cycle에 미치는 영향(影響)에 대(對)하여 시험검토(試驗檢討)하였다. 1. 포자형성최적농도(胞子形成最適濃度)는 N
