Multi-biomarker approach in the scallop Chlamys farreri to assess PAHs pollution in Qingdao coastal areas of China

A multi-biomarker approach for the scallop Chlamys farreri was used to assess PAHs pollution and to select biomarkers for PAHs along the Qingdao coast.

The Best Culture Conditions of Rhodopseudomonas spp. by Orthogonal Experiment

Four photosynthetic bacteriumRhodopseudomonas spp., QDS2, QDS3, QDS4and QDS9, were isolated and screened from the bottom sludge of Qingdao coast. In order to get a mass of PSB, we successfully optimized the culture conditions of four strains by orthogonal experiment and obtained the best culture conditions.

Study on Optimization of the Culture Conditions for Four Rhodopseudomonas spp.

Rhodopseudomonas sp. could be used in wastewater treatment and aquiculture, extensively. Four photosynthetic bacterium Rhodopseudomonas spp., QDS2, QDS3, QDS4 and QDS9, were isolated and screened from the bottom sludge of Qingdao coast. In order to get a mass of PSB, we successfully optimized the culture conditions of four strains by orthogonal experiment and obtained the best culture conditions. The research could provide the bases for the applying of high-effective PSB (Rhodopseudomonas sp).
