It was observed that genotypic difference was among stains from distinct sampling sites and strains that were picked out from some plates with similar culture characteristics . as to the same sampling location , different pretreatment and culture media showed similar selectivity on the active strains 对于同一采样点,不同预处理,不同培养基分离筛选到的活性放线菌间有较大的相似性,表明这几种预处理和培养基具有相似的选择特异性。
