【中文摘要】 11個靈芝菌株經兩種培養基、兩種鍺源的研究結果表明,鍺對靈芝菌絲體生長的影響因鍺源、培養基和菌株而異。以有機鍺Ge-132為鍺源,以棉籽殼為主料作培養基,鍺對靈芝菌絲體生長無任何不良影響,以無機鍺GeO_2為鍺源,用PDA培養基培養,則50mg/kg鍺即表現出輕度的抑制作用,隨著鍺濃度增加,抑制作用加劇。但菌株間差異很大,11個菌株在PDA培養基上耐GeO_2能力最強的為野生靈芝,最弱的為泰山靈芝。在1000mg/kg鍺濃度下,兩者的菌絲體生長量相差6.75倍。
【英文摘要】 The result of studying with eleven G. lucidium strains, two kinds of media and two kinds of germanium showed that the effect of Ge on mycelial growth of G. lucidum varied with Ge - sources, media and strains. Using organic germanium Ge- 132 as Ge- source with cotton seed hull as main materials for the medium, no negative effect of Ge on mycelial growth was found, while 50 mg/kg Ge in inorganic germanium GeO2 was enough to cause a slight inhibition effect on mycelia growing in PDA medium. It was proved in our study that with the increment of the concentration of the Ge added, the inhibition effect was intensified, and that different strains differed widely in their tolerance to GeO2 stress. Among 11 strains studied, the wild G. Iucidum was the most tolerant strain to GeO2 in PDA medium, Whereas the Tashan G. Iucidum was the least tolerant strain. The mycelial growth amount of these two strains cultured in PDA medium added with 1000 mg/kg Ge in GeO2 differed by 6.75 fold.
