文摘In the paper, differences between the juvenile Triploid Chinese White Poplar (TCWP) in saline soil and 5-year TCWP in normal soil are compared in terms of their APMP-pulping properties. The results show that the saline planting environment does not show obvious effects on pulping properties of juvenile TCWP.
文摘[目的]研究杨木APMP废液培养枯草芽孢杆菌SY1菌株(Bacillus subtilis)的适宜条件和转化液对番茄病原菌的拮抗作用。[方法]通过单因素实验对培养条件进行了初步优化;利用平板扩散法测定转化液对番茄病原菌的抑制作用。[结果]杨木APMP废液培养SY1菌株较适宜的条件为:pH值8.0,装液量75/250 m l,接种量5%,温度35℃;在此培养条件下SY1菌株的活芽孢数达3.96×108CFU/m l,废液COD转化率达59.52%。同时发酵液对供试的4种病原菌均有较强的抑菌作用。[结论]该研究为利用杨木APMP废液培养枯草芽孢杆菌的工业深层发酵提供了依据。
