Screening of hydrogen-producing aciduric Enterobacter aerogenes strain using He-Ne laser irradiation 激光诱变选育耐酸产氢菌产气肠杆菌
Results S.mutans was the predominant aciduric bacteria in fissures of caries-free children and more frequently recovered at neutral pH. 结果变形链球菌是无龋组窝沟的优势耐酸菌,且中性条件下检出较多;
CW-03 was isolated from crude oil well of more than 4 000 m deep. It is strictly anaerobic and not aciduric with maximum temperature of 68 ℃, and it can use the organic compounds with relatively short carbon chains as electron donors. 菌株CW03取自于4000多米深原油井的原油分离水中,严格厌氧,不耐酸,能够在68℃的温度下生长,可利用较短碳链的有机化合物。
Enterobacter aerogenes was irradiated by He-Ne laser to optimize the laser mutagenesis condition, and to test the heredity, aciduric and hydrogen-producing potential of the mutant. 运用He-Ne激光辐照产气肠杆菌(Enterobacteraerogenes),对激光诱变参数进行优化,考察了突变株的遗传稳定性、耐酸性和产氢特性。
Study on Genetic Diversity Within Acidogenic and Aciduric Virulence of Streptococcus Mutans from Caries-active and Caries-free Individuals Predominant Aciduric Microflora Related to Fissure Caries of the First Permanent Molars 不同龋敏感人群变形链球菌产酸耐酸毒力因子遗传多态性研究与窝沟龋有关的优势耐酸菌构成的分析
Primary study on acid tolerance mechanism of a wild aciduric Rhizobium strain isolated from Pueraria lobata 一株耐酸野生葛藤(Puerarialobata)根瘤菌的筛选与耐酸机理初步研究
An aciduric mutant with steady hydrogen-producing capability, which was able to grow at acidic pH of 3.0, was obtained. 结果筛选到一株遗传性状稳定的高产氢突变株,具有良好的耐酸性,在pH值3.0时仍能生长。
