The enzyme activity of LpsA2 was increased to 250% or above by 1 mmol/L Co2+, Hg2+ and Zn2+, respectively. The activity was also elevated to 110.7% and 138.0% by 15% dimethylformamide and dimethyl sulfoxide, and 352.7% and 189.7% by 0.1% and 1% Span-20, respectively. The enzymatic properties of LpsA2 from S. avermitilis were characterized that may provide the fundament to the screening of bio-engineered bacteria and the industrial applications in food processing and drug synthesis.

avermitilis的脂肪酶基因lpsA2进行了异源表达和酶学功能鉴定，不仅为脂肪酶的研究积累了更多数据，也为具有优良性能的脂肪酶生物工程菌的筛选奠定了基础，更为其在食品加工、药物合成等工业生产中的应用提供了依据。

Since 1996, the Rice Research Institute of Liaoning Province has laid stress on the genetic improvement of stigma exsertion rate of japonica male sterile lines. By introducing the genes of high stigma exsertion rate from indica into japonica, a group of japonica male sterile lines with high stigma exsertion rate have been successfully developed. Their stigma exsertion rate have been greatly increased from less than 30% to more than 80%, resulting in an increased outcrossing rate over 60% and a high seed production yield of 3.0~4.5 t/hm^2. Moreover, using these sterile lines, a group of new japonica hybrid rice combinations such as Liaoyou 5218 (Liao 5216A/C418), Liaoyou 1052 (Liao 105A/C52) have been developed and released to commercial production.

自1996年以来，辽宁省稻作研究所加强了粳稻不育系的柱头外露率遗传改良研究，通过导入籼稻的高柱头外露率基因，选育了一批高柱头外露率的粳型不育系，柱头外露率由原来的30%以下逐步提高到80%以上，异交结实率可达到60%以上，杂交制种产量可提高到3.0~4.5t/hm^2，并配组育成了辽优5218（辽5216A/C418）、辽优1052（辽105A/C52）等杂交粳稻新组合，在生产上得到了大面积推广应用。
