Bacteria ecology in planting-culturing system

Abstract

Abstract: ng system in inter tidal zone is a new type eco-culturing model.The survey on bacteria biomass and water quality in the designed planting culturing system in inter-tidal zone showed that the mangrove planted in the system improved water quality and made water quality to Ⅱ～Ⅲ type,better than the Ⅳ and Ⅴ type in the control pond.Designed ponds made heterotrophic bacteria,vibrio,phosphorus bacteria and enzyme-producing bacteria populations 1～2 order lower than the control pond without mongrove planting.Correlation analyses with CORREL software showed that the biomass of these bacteria was positively related with the nitrogen and phosphorus contents in water of the system,and the correlation coefficient for heterogeneous bacteria and vibrio was up to 0.9205.Heterotrophic bacteria and vibrio could be used as the water-quality monitoring organisms.

Key words: Plant-culture system, Mangrove, Bacteria ecology
