TÓM TẮT
Microalgae cultivation in wastewater for many purposes has been investigated for recently decade ago. In this study,
Chlorella vulgaris
was chosen to culture for examination of its influences on microorganism of seafood wastewater in particular aerobic bacteria,
Coliform
and
E. coli
. The microalgae cultivation was realized in Erlenmeyer flasks containing seafood wastewater medium. Another was also grown in original medium called Sueoka medium for control. All of experiments were set up until almost
Chlorella vulgaris
decanted or flocculated in the bottom of flasks. The changes of bacteria counts including aerobic bacteria,
Coliform
and
E. coli
were measured to evaluate the impact of cultivation of
Chlorella vulgaris
on them in this sewage. Otherwise, the growth of microalgae has been also recorded for evaluating the effect of a new medium on metabolism of
Chlorella vulgaris
. The results showed that the bacteria counts were significantly reduced after day 3 of microalgae culture. These results have been calculated the efficiency of aerobic bacteria,
Coliform
and
E. coli
elimination out of wastewater medium represented approximately 70%, 81% and 90% respectively. These eliminations provided evidences of difficult metabolism of bacteria under the presence of microalgae as like as
Chlorella vulgaris
. In other words, the symbiosis of microalgae and bacteria in sewage could prevent the raising of bacteria counts.
