主　　题：Wheat bran Nutrient Algae Teabag 

摘      要：The growths of algae under different concentrations and treatments of wheat bran were studied in order to investigate the feasibility of wheat bran as the sole nutrient source of Platymonas helgolandica *** results showed that adding wheat bran directly to the algal fluid can promote algal *** algal growth was inhibited for the first 10 d and accelerated dramatically *** the comparison between the algae whose growth was modified by using wheat bran packed in a teabag or boulting cloth bag,and that by using loose wheat bran only,results showed that,at the same concentration,the algae grew faster and without lag phase when the wheat bran was packed in a teabag or a boulting cloth bag than when loose wheat bran was used *** addition,when the wheat bran was packed in a boulting bag,the algal growth was slightly better than when the wheat bran was packed in a *** the concentration of wheat bran ranged from 0.5 to 4 g/L,the cell density rose with the increase of the concentration of the wheat bran,however,the algal growth was inhibited completely at 8 g/*** a concentration of 4 g/L,the fast-growth phase of the algae with the wheat bran aerobic pretreatment started 6 d earlier than that with wheat bran packed in a teabag,whereas there was no significant difference between them in final cell *** terms of cell growth,the algal growth at 1 g/L wheat bran was close to that at f/2 medium during the experimental *** study showed that it is feasible to use wheat bran as the sole nutrient source for the culture of Platymonas helgolandica ***.
