Rhizobacteria belonging to Bacillus sp. were isolated from the rhizosphere of chickpea (Cicer arietinum). Ten Bacillus strains were studied for their antifungal activity, effect on seedling emergence and plant growth promotion. Two Bacillus strains CBS127 and CBS155 inhibited the growth of all the four pathogenic fungi tested on nutrient agar medium plates in vitro. Seed inoculation with different Bacillus strains showed stimulatory effect on root and shoot growth at 10 d of observation in comparison to control whereas four Bacillus strains CBS24, CBS127, CBS129 and CBS155 caused retardation of shoot growth at 10 d. Maximum nodule-promoting effect was observed with Bacillus strains CBS106, CBS127 and CBS155. The symbiotic effectiveness of Mesorhizobium sp. Cicer strain Ca181 was further improved on coinoculation with six Bacillus strains i.e. CBS9, CBS17, CBS20, CBS106, CBS127 and CBS155 at 80 d of plant growth under sterile conditions and shoot dry weight ratios increased 1.62 to 1.74 times those of Mesorhizobium-inoculated treatments, suggesting the usefulness of introduced rhizobacteria in improving crop productivity.
从鹰嘴豆（Cicer arietinum）根际中分离出属于芽孢杆菌属的根际细菌。研究了 10 株芽孢杆菌菌株的抗真菌活性、对幼苗出苗和植物生长促进的影响。两株芽孢杆菌 CBS127 和 CBS155 在体外抑制了所有 4 种致病性真菌在营养琼脂培养基平板上的生长。与对照相比，不同芽孢杆菌菌株的种子接种在 10 天的观察期内对根和芽的生长表现出刺激作用，而 4 株芽孢杆菌 CBS24、CBS127、CBS129 和 CBS155 在 10 天导致芽生长迟缓。芽孢杆菌菌株 CBS106、CBS127 和 CBS155 表现出最大的根瘤促进作用。在无菌条件下，Mesorhizobium sp. Cicer 菌株 Ca181 与 6 株芽孢杆菌菌株（CBS9、CBS17、CBS20、CBS106、CBS127 和 CBS155）共接种，进一步提高了共生有效性，在 80 天的植物生长期间，茎干重比增加了 1.62 至 1.74 倍，这表明引入的根际细菌有助于提高作物生产力。
