水华鱼腥藻厚壁孢子的诱导效应研究
Study on the effect of inducing Anabaena flos-aquae akinetes
摘要
Abstract
The effects of pH,nutrients,and temperature on the formation of Anabaena flos-aquae akinetes were studied by microscopic count.The results revealed that the akinetes could be formed more easily in a neutral or somewhat acidic culture fluid than the control at pH 8, and at pH 6 and pH 7 the akinete content could be up to 4.58％ and 6.80％, respectively.The number of the akinetes induced by K2HPO4 ,KNO3 ,saccharose and glucose nutritive materials and by the control presented a marked regularity of first increasing and then decreasing.Both saccharose and glucose treatments could significantly induce the akinete formation, with the inductivity being 15.29％ and 10.83％,respectively.At 4 ℃ low temperature a large number of the akinetes could still be formed, and the akinete content could reach 6.13％.关键词
