摘要
鏈黴菌 LN17 (AN17, 農新17) 系1970年在廣西桂林土壤中分離的 菌株. 經大田試驗, 發現它具有刺激作物生長, 抑制某些 病菌的作用, 其效果相當或優於涇陽鏈黴菌 (Streptomyces jingyangensis). 經鑑定, 該菌株為淡紫 灰(薰衣草)鏈黴菌的一個新亞種, 定名為淡紫灰鏈黴菌不 液化亞種 (Streptomyces lavendulae subsp. nonliquefacins Yan, Yan & Zhang).
Abstract
The strain LC 265 was isolated from bean curd in cold storage in Beijing. The cells of the strain are rods or filaments, measuring 0.6-1.0 by 1-15.0 micrometer,gram-negative, non-flagellated, gliding movement, no sheath, reproduction by schizogenesis, resting stages not known.
Colonies of strain LC 265 are mucilaginous, yellow to orange coloured, first convex and rough, then spreading out into a thin layer,smooth and translucent. The pigments are non-fluorescent, and are carotenoids. The maximum absorption pesk of the pigments in n-hexane is 446 nm.
The temperature range for growth is 5 to 35'C, minimum, 5'C, optimum, 18 to 25'C, maximum, 35'C (very week growth or almost no growth at 35'C),the pH range for growth is 5.5 to 9.0, optimum growth occurred at pH 6.5 to 8.0. This strain may be tolerable of 4% NaCl, 80 ug/mL of streptomycin and of ampicillin.
Strain LC 265 is aerobic, and metabolism is repiratory. Many sugars are utilized and alkalified. It hydrolyzes starch, but cellulose(CMC or filter paper), chitin and agar are not attacked. This strain hydrolyzes casein, and peptonizes litmus milk and turn it alkaline.Gelatin is liquefied. Nitrate is reduced to nitrite. M.R.and V. P. tests are negative. H2S and indole are produced. Catalase and oxidase are positive.
The guanine plus cytosine content of deoxyribonucleic acid of the strain LC 265 is 32.2%.
This strain belongs to the genus Cytophaga when it is compared with the descriptions of the genera Flavobacterium, Flexibacter, Microscilla andLysobacter, but it deffer significantly from strains of previously described species. Therefore, it is regarded as a new species. According toits character of growth at lower temperature, the name Cytophaga psychropha is proposed. A culture of the type strain, LC 265, has benn depositedin the Culture Collection Department, Institute of Microbiology, Academia Sinica under the number AS 1.1780.
