一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Germicidin is a pyranone antibiotic originally excreted by Streptomyces viridochromogenes NRRL B-1551. Germicidin has an inhibitory effect on the germination of its own arthrospores at a concentration as low as 200 pM (40 pg/ml). Higher concentrations of germicidin inhibited porcine Na+/K+-activated ATPase and retarded the germination of the cress Lepidium sativum with an ID50 of 100 μM. Germicidin was the first known autoregulative inhibitor of spore germination in the genus Streptomyces and was isolated from the supernatant of germinated spores, but also from the supernatant of the submerged culture [1].
Germicidins B inhibited germination of S. coelicolor A3(2) spores above 1 μg/ml. The S. coelicolor A3(2) spores collected from a single petri dish (9 cm i.d.) contained 5.4 μg of germicidin A (~2.7 × 10-14 g per spore) and contents of germicidins B, C and D were 0.2–0.8 μg. The activity of the spore extract corresponded well with the sum of the activity of each germicidin. Germicidins functioned as self-germination inhibitors in S. coelicolor A3(2) [2].
