Abstract

The excretion of glycolate by illuminated Chlorella vulgaris cells at low CO2 tension can be stimulated about tenfold by substituting O2 for air, or by addition of cyanide, hydroxylamine, hydrazine or semicarbazide to the cells in air. For each reagent there is a concentration range giving a maximum effect. It is proposed, as a working hypothesis, that the HCN formed internally when the cells are illuminated in O2, may cause the glycolate excretion.

摘要

在低二氧化碳张力下，光照的普通小球藻细胞排泄乙醇酸的量，通过用氧气替代空气，或向空气中的细胞添加氰化物、羟胺、肼或氨基脲，可被刺激增加约十倍。对于每种试剂，都有一个产生最大效应的浓度范围。作为一个可行的假设，有人提出当细胞在氧气中光照时内部形成的HCN可能导致乙醇酸的排泄。
