集落大小

Were studied together with the reference strains of recognized rhizobium and bradyrhizobiwn species by performing polyphasic taxonomy , including numerical taxonomy , rep - pcr fingerprinting , 16s rdna pcr - rflp . the result show that : the growth rate of rhizobia isolated from the root nodules of pueraria spp . showed great diversity . ccbau41147 ccbau6110 k ccbau61096 and ccbau61095 were fast - growing strains , the single colony size was bigger than 1mm after 2 days incubated oq yma medium at 28 they can produce acid . the other strains were slow - growing strains , their single colony size was less than 1 mm after 7 days incubated on yma medium at 28 . they can produce alkali
本研究以从我国四川、河南、安徽和湖南等地分离的32株葛藤根瘤菌为研究对象，以20株已知种的根瘤菌为参比菌株，采用数值分类、 rep - pcr指纹分析、 16srdnapcr - rflp指纹分析等现代根瘤菌分类技术，初步研究了葛藤根瘤菌的生物多样性和分类地位，结果表明：葛藤根瘤菌在生长速率上表现出多样性，菌株ccbau41147 、 ccbau61096 、 ccbau61101和ccbau61095生长较快， yma培养基上28培养2 - 3天后，单个菌落直径大于1mm ，具有产酸能力，是快生型葛藤根瘤菌；其余待测葛藤根瘤菌生长较慢， yma培养基上28培养7天后，单个菌落直径小于1mm ，具有产碱能力，是慢生型葛藤根瘤菌。
