Fixing bacteria in rice root type and number of joint


Two strains of rhizosphere and root Table 3: strains, 1 strain of roots, number: A5, A. , B, B a C,[link widoczny dla zalogowanych], B. Mu are Gram negative bacteria, cells were rod-shaped, single polar flagellum. Moss on the bacteria in the agar producing yellow, orange, non-water-soluble pigment. B. Staining is uneven, the body can be seen a number of bacteria pale granular material. Six strains showed off Zhuo round, protruding, semi-transparent, edges neatly. Does not reduce nitrate, catalase positive. Zhejiang Agricultural University 1g report 2.2JT Escherichia Yin is (Esche ~ ichia) 5 socks 4 in the rhizosphere. Roots 1,[link widoczny dla zalogowanych], number: Ce, mm, A. . ,, AA a:, and its features are: straight rod-shaped bacteria, Zhou flagella movement, gram negative. Colonies of small,[link widoczny dla zalogowanych], gray head. Produce indole, methyl red test was positive, V. P reaction negative. Do not use citrate. Phenylalanine deaminase negative. Yan is a gut shot 2.2.8 (Enlerobacter) 5 2 strains in the rhizosphere, the root table 2, within a root, number IB �� hC. . , A'_lAll'B. One. Its characteristics are non-Bacillus gram-negative, in weeks flagella movement. Can use citrate and acetate as sole carbon source. Fermentation of glucose produce acid and gas. V. P test positive, I drink a noise reaction,[link widoczny dla zalogowanych], methyl red test was negative. Three sugar milling (TSI> agar medium does not produce sulfide chlorine. Do not have the phenylalanine deaminase. The study found that the joint fixing bacteria in the rhizosphere soil composition to a maximum of Alcaligenes sp. Followed by Clay Borrelia spp, Escherichia Velvet genus, Pseudomonas, Enterobacter, Flavobacterium, Azotobacter spp. root sheets are Bacillus-based, then the Pseudomonas, Flavobacterium , nitrogen-fixing bacteria genera, Alcaligenes spp, Enterobacter spp. roots nitrogen-fixing nitrogen-fixing bacteria is composed of the order of Bacillus, Pseudomonas, Klebsiella spp, Enterobacter, Escherichia coli genus Flavobacterium. rice root zone in different parts of the United nitrogen-fixing bacteria and the number and type of separation is no doubt the medium used, culture conditions, rice breeds. Thompson and Skerman reported mannitol or glucose as the carbon source easily separated from the medium to Azotobacter Okon ~ reported by malate medium conducive to the growth of Azospirillum .1 waowatanabe [51979 compared the 10 years of experimental medium in Rice Rhizosphere effect of aerobic heterotrophic nitrogen-fixing bacteria, that the medium A best, this study is using this medium. Balaadreau [8 reported Taiwan nitrogen-fixing bacteria in rice root zone associated with Enterobacteriaceae (E ~ terobaet-eriaceae) for many, Watanabe also confirmed in rice root zone of Enterobacteriaceae associated Taiwan, an important component of nitrogen-fixing bacteria. Our study reported similar results and Watanabe, a total of 19 strains of Enterobacteriaceae, total (75) 25%, followed by 18 strains of Alcaligenes genus, accounting for 24,[link widoczny dla zalogowanych], and Enterobacteriaceae bacteria mainly in the rhizosphere soil. thank our side of the room are electron microscope, electron microscope Xu two comrades to assist
