猪场污水中浮萍生物量和淀粉含量变化研究
The analysis of the biomass and starch content of duckweed growing in swine wastewater
摘要
Abstract
The biomass and starch content of duckweed Lemna minor, Spirodela olygorrhiza , L. per-pusilla and S. polyrrhiza, collected from Chengdu in Sichuan. were investigated when they were cultured in swine wastewater. The results showed the common duckweed could grow fast in the 5 % swine waste water. At an optimal initial inoculum size of 35. 4 g/m2, the maximum starch content of Lemna minor was 32. 9% on a dry weight basis. At an optimal initial inoculum size of 17. 7g/m2. the highest starch content of S. olygorrhiza, L. perpusilla and S. polyrrhiza was 44. 4% ,38. 0% and 35. 5% on a dry weight basis, respectively. In the climate condition of Chengdu, S. polyrrhiza could produce the most biomass and S. olygorrhiza could produce the most starch. S. polyrrhiza could produce 89. 7 tons biomass(fresh weight) per hectare per year. S. olygorrhiza could produce 11. 4 tons starch per hectare per year and would be able to be a new energy plant widely used.关键词
