The complex biological preservatives consisting of lysozyme and / or nisin possessed a good preserving effect on razor clam, with the combination of lysozyme and nisin better than the individual one, possibly because the condition of their application and anti-bacterial spectrum can supplement each other as to increase their anti-bacterial spectrum.Razor clam was hydrolyzed with four kinds of proteases including subtilisin, flavourzyme, bromelain and acid protease.

用溶菌酶、乳酸链球菌素等组成的复合生物保鲜剂处理，结合冷藏保鲜蛏肉，各保鲜剂组的总挥发性盐基氮和细菌总数增加速度均慢于普通冷藏的蛏肉，从色泽、弹性、气味、黏度等感官评定指标来看，保鲜效果也均明显优于普通冷藏，说明溶菌酶、NISIN等对蛏肉具有较好的防腐保鲜效果。

Quantitative analysis of protein adsorption: The PS suspension containing lysozyme was subjected to ultracentrifuge (15 000 r/min) to collect clear aqueous solution. The lysozyme concentration in the clear solution was measured by spectrophotometry at 280 nm. The amount of protein adsorbed on PS surface was calculated based on the decrease in the protein concentration in the supernatant solution.

蛋白吸附定量分析：采用高速离心(15 000 r/min)法从含溶菌酶蛋白的聚苯乙烯悬浮液中分离出上清液，用紫外(280 nm)分光光度法测定经聚苯乙烯微球表面吸附后，液相蛋白质量浓度的下降值，由此推算蛋白在聚苯乙烯表面的吸附量。

结果表明，酒酒球菌SD-2a原生质体制备的最佳条件为：菌龄20 h，青霉素G钠质量浓度0.5μg/mL，酶质量浓度1mg/mL，酶解时间30 min，渗透压稳定剂采用SMM缓冲液，再生培养基采用添加0.7 mol/LKCl的ATB培养基，再生培养时采用双层培养基厌氧培养，可以保证较好的形成率和再生率。

RESULTS:① Suspension of bare PS microspheres flocculated in the presence of lysozyme at 37℃ due to protein adsorption, which caused significant decrease in the turbidity of the suspension. Bare PS surface could adsorb 25.5 mg lysozyme per square meter.

结果：①37 ℃下未经预吸附改性的聚苯乙烯微球与溶菌酶接触后，因蛋白在聚苯乙烯表面吸附导致悬浮液发生絮凝、浊度显著下降的现象，原始聚苯乙烯表面蛋白吸附量达25.5 mg/m2。

Comparing with chicken egg-white lysozyme which is widely used in clinic, hLYZ has many advantages: it is a natural protein in human body, so it is safe and harmless when used as a drug; its bioactivity to kill bacterium is three times higher than chicken egg-white lysozyme, and its thermal stability is much higher, too; it also has many other specific important functions which are not related with its catalysis, such as anti-virus and anti-tumor and improving immunization.
