Compared with the parent strain ②, the glutathione concentration in the main fermentation broth of strain A 27 increased by 20%, the carbonyl compound content decreased by 14%, and the flavor resistance staling value increased by 37%.

在锥形瓶中连续发酵 5代后，与A2 7菌株相比，MI4 菌株发酵液中GSH浓度高4 4 %，TBA值低 2 4 %，主酵液RSV值高 77%，且遗传稳定性明显提高：连续传代 5次后，MI4 菌株胞内GSH含量基本不变，而A2 7菌则下降了 2 2 %。

From its the depart in splanchnic organization arrives bacterium of 2 individual plant, pass bacteriological method appraisal, one individual plant is deputy pig bloodsucking bacili, another individual plant is a pig streptococcic; will send check sample book have an inoculation to marc-145 cell, can observe cellular pathological changes, the pcr of virus fluid classics of results detects, for positive of blue ear ill viru

从其内脏组织中分离到2株细菌，通过细菌学方法鉴定，一株为副猪嗜血杆菌，另一株为猪链球菌；将送检样本接种到marc-145细胞，能观察到细胞病变，收获的病毒液经pcr检测，为蓝耳病病毒阳性；将送检的样本接种spf鸡胚，收获的鸡胚尿囊液有血凝性，血凝试验和血凝抑制试验鉴定为猪副黏病毒。

Among the bacterial strains, 5 strains of RP,RS,RT,RX and RY were suscept ib le to all 20 phage strains, so they could be used as indicative bacteria for det ecting the phage particles in checking samples in order to forecast bacterial le af s treak of rice with the bacteriophage isolation technique in Hubei Province.

根据它们相互的亲和关系，可把10个细条病菌菌株划分为6个组，把20个噬菌体划分为7个溶菌型；其中RP、RS 、RT、RX、RY等5个细条病菌菌株可与所有参试的20个噬菌体发生亲和反应，据此在用噬菌体技术进行湖北省水稻细菌性条斑病的测报工作中，这些广亲和性的菌株可作为指示菌。

The cell adaptability tests showed that the CPE caused by wild CCV strains were different from reference strains syncytia CPE.

细胞适应性试验表明，分离到的野毒在A72细胞上导致的CPE不同于参考毒株的合胞体病变，NJ2、KM株主要导致细胞圆缩、脱落，NJ2株的6-15代在A72细胞上有CPE，但是15代后不再出现CPE。

Hemagglutinin thermostability and hemagglutination spectrtum tests: Large variations in hemegglutinin thermostability of 8 different regions of SIV isolates were detected, with SWTJ/01/04, SWHN/01/06, SWCB/01/04 and SWAH/01/06 being thermstabile and other 4 thermolabile.

血凝素热稳定性和血凝素凝集谱分析：不同地区SIV分离株的血凝素热稳定性差异较大，其中SWTJ／01／04、SWHN／01／06、SWCB／01／04、SWAH／01／06分离株表现为热稳定型，其他4株表现为热不稳定型。

To test the influence of trehalose accumulation on response to freeze stress, we constructed all single and double gene disruption mutants of the trehalase genes ATH1, NTH1 and NTH2 and examined the changes of their trehalose accumulations and their freeze tolerance.
