Its aerial mycelium is white,substrate mycelium is colorless to cream or pink. 其气生菌丝白色 ,基内菌丝无色至乳脂或浅粉 ;
Spore bearing chain, developed from aerial mycelium, can be turned in spores. 孢子丝:由气生菌丝分化而来的能够形成孢子的菌丝.
Str.ery threus 2-62 is a phage P4 lysogenic strain.It is an erythromycin producer and rich in aerial mycelium. 摘要 2-62菌株是一溶源性菌株，合成红霉素能力稳定，气生菌丝生长良好。
The substrate mycelium have no branch,the aerial mycelium become the spore chain and the spore chain bears wave or straight forms. 该菌株在大多数培养基上生长良好,基内菌丝无横隔,不断裂,气生菌丝体形成孢子链,孢子丝呈波曲或直形。
The 4 kinds of agent change into circular, then concentric circle;aerial mycelium first appears lacte, then changes into cinereous or black, aerial mycelium grows luxuriantly. 气生菌丝起初均为乳白色，后期为青灰色或者黑色，气生菌丝生长旺盛；
