Investigation of Total Bacteria,Total Coliform and Fecal Coliforms on Huixian Wetland in Guilin,China

Investigation has been done into Huixian Wetland in which track tests were carried on for one year in terms of Total Bacterial Count,Total Coliform;Fecal Coliforms and 7samples were taken from different places of Huixian.The total bacteria(mL-1),Coliforms(mL-1)and Fecal coliform were analyzed by microbiological methods.The results indicate that the number of Coliform(mL-1)is 8 971,1 901,3 823,512,Fecal coliforms(mL-1)4 385,432,20,85 and total bacterial 2 314,27 000,1 500,3 414,which shows clearly that the total bacteria rise evidently in summer.By multi-tube fermentation method,the number of Total Coliforms is 8 971,1 901,3 823,512 MPN·L-1 and Fecal Coliforms is4 385,432,20,85 MPN·L-1.The results indicate that Total Coliforms and Fecal Coliforms rise evidently in spring.
