摘要: 项圈藻是程海湖中一优势种。在实验条件下,其生长的最适温度为25℃,光照强度为6000Lx,光照时间为24h昼夜连续光照,NO3--N 为10.00mg·L-1,PO43--P 为1.00mg·L-1,CO32--C为150.00mg·L-1,Fe3+ 为1.00mg·L-1,PH为9.0.其最大增长率为0.817,最短增倍时间为0.85d.其粗蛋白、粗脂肪、总糖和灰份的含量分别占干重的61.25、5.30、20.34和8.25%;氨基酸含量为52.63%.

Abstract: Anabaenopsis sp.is the dominant species in Chenghai lake. Under laboratory condition,the optimum temperature for its growth is 25℃,light intensity is 6000 Lx, photoperiod is 24h,concentrations of NO3-,PO43--P,CO-C andFe3+ are respectively 10.00,1.00,150.00 and 1.00mg·L-1,and PH is 9.0.Its maximum growth rate is 0.817,and the minimum multiplication duration is 0.85 days.The contents of its raw protein,lipid, carbohydrates and ash are respectively 61.25,5.30,20.34 and 8.25%(dry weight),and its amino acid content is 52.63%.
