| Abstract: | Influences of salinity and pH value on reproduction,protein content and extracellular polymeric substances(EPS) of benthic diatom Cylindrotheca closterium(Ehr.) Reimann et Lewin were studied.Salinity and pH value fit to C.closterium were 15 and 8,respectively,showing brackish water species.Abundant EPS were secreted by C.closterium characterized by brackish water species under high salinity(>15) and low pH(<8) stress,showing functions in abnormal conditions.The fraction of EPS that was closely bound to the cells(attached EPS) and the soluble fraction(colloidal EPS) were produced in different amounts at the different salinity and pH value.This suggested that the production of the 2 operationally defined fractions of EPS might serve different functions.No significant differences were found on intracellular carbohydrate production of C.closterium under different salinity and pH value. |
