低盐度形成的微生物膜对厚壳贻贝稚贝附着的影响
Settlement of the mussel Mytilus coruscus plantigrades in re-sponse to biofilms formed on low salinities
摘要
Abstract
The influence of low salinity formed biofilms on the settlement of the plantigrade Mytilus coruscus was investigated in the laboratory. Various aspects of biofilms were examined including age, dry weight, chlorophyll a concentration, bacterial and diatom densitie. The diversity of bacterial community structure was analyzed by fin-gerprint technique DGGE. It is found that the settlement of M. coruscus was promoted by the biofilms which are formed when the salinity is 13 or 23. Furthermore the adhesive rate reached maximum value 72%when the salinity is 13 or 23. It is indicated that the inducing activity of biofilm was positively correlated with salinity, biofilm age, dry weight and bacterial and diatom densities, but uncorrelated with chlorophyll a concentration. The dry weight, bacterial densities and diatom densities in biofilm increased with biofilm age, but chlorophylla was uncorrelated with biofilm age. Overall, this investigation indicates that bacterial structure may play an important role in the ad-hesion of the plantigrade M. coruscus, which can be induced by low salinity formed biofilms.关键词
