saprophyte
saprophytic bacterium
saprobe
- 作为腐生菌,它可能损害生物机体并具有一定致病性和传染性。
They can occur as spoilage organisms and some are pathogenic causing infections. - 具体的做法是:采用岩心流动试验确定悬浮固体含量、颗粒直径中值、含油量、铁细菌和腐生菌五项控制指标;采用旋转腐蚀挂片实验确定硫酸盐还原菌和平均腐蚀率指标;采用结垢预测和敏感性实验确定平均结垢率和总矿化度指标。
The specific methods: 1. to ascertain five control indications including suspended solid content, grain diameter median, oil content, iron bacteria and saprophytic bacteria by carrying out the experiment of core flow; 2. to ascertain indications of sulfate reducing bacteria and average corrosion rate by carrying Out the experiment of revolving corroded test pieces; 3. to ascertain indications of average scaling rate and total mineralization degree by carrying out the experiment of scaling prediction and sensibility. - 真菌通常为腐生或寄生,由单细胞或丝状体(称为菌丝)组成,它们构成菌体或菌丝体。
Hyphae may grow loosely or form a compacted mass of pseudoparenchyma giving well-defined structures, as in toadstools.
