The cytoplasmic ribosomes from Euglena gracilis var. bacillaris are found to be of two types taking into consideration their stability "in vitro". In the group of unstable ribosomes the large subunit is degraded. The other group apparently does not suffer any degradation under the conditions described. However the RNAs extracted from both types of ribosomes are degraded during sucrose density gradients. The degradation of the largest RNA species has been reported previously, but no comment has been made about the stability of the ribosome itself.
考虑到纤细裸藻杆状变种的细胞质核糖体“在体外”的稳定性，发现其有两种类型。在不稳定核糖体组中，大亚基会降解。在所述条件下，另一组显然未发生任何降解。然而，从这两种类型的核糖体中提取的RNA在蔗糖密度梯度过程中会降解。此前已报道过最大RNA种类的降解，但未对核糖体本身的稳定性作出评论。
