查询词典 isolates

Isolates from watermelon-growing areas were classified into 3 races like race 0, race 1 and race 2 which were 8 (17.4), 30 (65.2), and 8 (17.4%), respectively. Pathogenecity of race 0 isolates are weakest which only make Sugar Baby susceptible; isolates of race 1 are intermediately pathogenetic, they make Sugar Baby and Charleston susceptible Gray but Calhoun Gray resistant; isolates belonging to race 2 possess the strongest pathogenecity, which make 3 hosts susceptible. Isolates of race 0 mainly distribute over the central and southern Hebei province, whereas race 2 cover the middle and north of Hebei, isolates of race 1 exist in the whole watermelon-growing areas in Hebei province.

The results showed:among the 7 isolates, five isolates of HY3、GY1－3、ZJ1－1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.

According to the ability of the field isolates of Gibberella zeae to grow on the PSA with varying carbendazim concentrations, three sensitivity levels of isolates were determined in vitro. The sensitive isolates could grow at 0.5 μg/ml, but could not grow at 100 μg/ml. The high resistant isloates could grow faster than R at 50 μg/ml, and also could grow at 100 μg/ml.No low resistant isolates, that could grow fast at 1.4 μg/ml but could not grow at 50 μg/ml, were found among the field isolates.

In this study, isolate 23 microbes with lipase activity from Wu-Jie scrap heap at Ilan and Taichung Environmental Protection Section. When the microbes incubator in 50oC, there are isolates B61 and M63 that lipase activity are better than others. Brevibacillus borstelensis SH168 isolated from NTU resterant food waste compost is used as control check. Isolates B61, M63 and Brevibacillus borstelensis SH168 determine the lipase activity by the LB with tributyrin. The lipase activity of isolates B61 and M63 are 2~3 fold higher than Brevibacillus borstelensis SH168. So isolates B61 and M63 are more useful in producing lipase. Isolate B61 can grow at pH 5~9, and at temperature 20oC ~ 60oC; isolate M63 can grow at pH 6~10, and at temperature 30oC ~ 50oC. Isolates B61 and M63 were identified by 16S rRNA. Isolate B61 is Bacillus circulans, and isolate M63 is Bacillus species.
