盐度和藻种密度对牟氏角毛藻生长及其用于养殖尾水处理效果的影响
Effects of salinity and algae density on the growth of Chaetoceros muelleri and its application in aquaculture tail water treatment
摘要
Abstract
To investigate the effects of salinity and inoculation density on the growth of Chaetoceros muelleri,a single-factor experiment was conducted to study the effects of different salinity and inoculation density on the growth and cellular biochemical composition of C.muelleri,as well as the effects of inoculation densities on the removal of nitrogen and phosphorus in the water.The results showed that different salinity and inoculation density had significant effects on the specific growth rate(SGR),protein,and fat content of C.muelleri(P<0.05).Under the cultivation conditions with 20 salinity,the maximum SGR of C.muelleri was(0.117±0.001)/d,there was no significant difference between 15 salinity and 20 salinity groups(P>0.05).The proportion of protein and total fat of C.muelleri was the highest under the cultivation condition with 15 salinity.When the inoculation densi-ty was 0.694×106 cells/mL,the SGR of C.muelleri was the highest,reaching(0.210±0.001)/d.Meanwhile,the removal rates of NH4+-N,NO3--N and PO43--P in the water were also the highest,and significantly exceeded those of other inoculation density groups(P<0.05),which were(97.75±0.18)%,(76.64±0.35)%and(96.70±0.35)%,respectively.In conclusion,large-scale cultivation of C.muelleri could be carried out under the conditions of 15-20 salinity and inoculation density of 0.694×106 cells/mL.关键词
