- 摘要:
- 对大多数微生物来说,游离氨基酸及短肽都可通过细胞膜直接吸收,这种吸收行为必然对微生物的生长及活性造成影响。通过对目前该领域的研究情况进行总结概括,并对其在生物冶金领域的应用前景进行了展望。
- Abstract:
- The dry seeds of four varieties of Echinochloa were carried by the recoverable satellite “shi jian 8”, seeds were not carried by the recoverable satellite “shi jian 8” as control. The results showed that the mitotic index of four varieties carried by the satellite was higher than control. There were different aberrations in root tip cells, including micronucleus, lagging chromosome, dissociative chromosome、chromosome bridge, chromosome fragment etc. The micronucleus rate and aberrant chromosome rate of four varieties wasn’t significances difference.
