摘    要:After the single-strain abilities of organic-pollutant-degrading bacteria in bioremediation of sediment environment of shrimp culture are determined, the multistrain degrading effect of the compositions of different strains is measured. The results indicate that the multi-strains groups have higher degrading ability than the single-strain groups. Three-strain groups are better than two-strain groups, and fourstrain groups are better than three-strain groups and five-strain groups, the groups composed of strains Lt7222, Lt7511. Fc6308 and Gy7018 has the best degrading effect, the CODMn removal rate is 73.2 % in 66 h, and gets to 82.7% in 114 h. 30% higher than that of the best single-strain group; Groups of Lt7222. Lt7511. Lt7451 and Gy7018 are the second, whose CODMn removal rate is 82.1% in 114 h. It is suggested that multi-species bacteria be used as thnctional bacteria in bioremediation of mariculture environment.

Abstract:After the single-strain abilities of organic-pollutant-degrading bacteria in bioremediation of sediment environment of shrimp culture are determined, the multi- strain degrading effect of the compositions of different strains is measured. The results indicate that the multi-strains groups have higher degrading ability than the single -strain groups. Three-strain groups are better than two-strain groups, and four-strain groups are better than three-strain groups and five-strain groups, the groups composed of strains Lt7222, Lt7511, Fc6308 and Gy7018 has the best degrading effect, the CODMn removal rate is 73.2 % in 66 h, and gets to 82.7 % in 114 h, 30 % higher than that of the best single-strain group; Groups of Lt7222, Lt7511, Lt7451 and Gy7018 are the second, whose CODMn removal rate is 82.1 % in 114 h. It is suggested that multi-species bacteria be used as functional bacteria in bioremediation of mariculture environment.
