在充分认知生物质原料在化学成分、结构组成、酶解及发酵性能上的不均一性的基础上,提出“组分选择性拆分-功能经济性利用”的生物质炼制新途径,即最大限度保持生物质大分子原有结构、尽可能激活适于酶解组分的生物活性,同时实现中间产物最大价值化。基于生物质原料特性、转化过程和产品要求的关联,笔者创新性地构建了多条生物质炼制产业链,验证了生物质“组分选择性拆分-功能经济性利用”的生物质炼制工业技术体系的可行性、合理性和可靠性。“组分选择性拆分-功能经济性利用”是突围生物质炼制生物燃料、生物材料和生物化学品的经济技术问题的必由之路。

The concentration and components of manure phosphorus (P) are key factors determining potential P bioavailability and runoff. The distribution of P forms in swine, poultry and cattle manures collected from intensive and extensive production systems in several areas of China was investigated with sequential fractionation and a simplified two-step (NaHCO -NaOH/EDTA) procedures. The mean total P concentration, determined by the sequential fractionation procedure of intensive swine, poultry and cattle manure, expressed as g·kg , was 14.9, 13.4 and 5.8 g·kg , respectively, and 4.4 g·kg in extensive cattle manure. In intensive swine, poultry and cattle manure about 73%, 74% and 79% of total P, respectively, was bioavailable (i.e., P extracted by H O and NaHCO ) and 78% in extensive cattle manure. The results indicated the relative environmental risk, from high to low, of swine, poultry and cattle manure. There is considerable regional variation in animal manure P across China, which needs to be considered when developing manure management strategies.
