After analyzing purple soil sampled from neijiang, leshan ofsichuan provinec and yuanmou of yunnan province, the contrast results of microbe quantity feature between surface and subsurface purple soil were obtained as follows. the content of soil organic matter, total and available nitrogen, phosphorous and potassium of surface was higher than subsurface, not relating to the type of purple soil and soil utilization way. the quantity of microbe _ bacteria, actinomyces and mould in surface purple soil was higher than subsurface, which indicated that the organic matter and airy condition in surface soil was more suitable for microbes growing. there was the same tendency in profile change of microbe quantity in purple soil located in temperate _ humid climate of sichuan basin in contrast with dry _ hot climate of yuanmou, yunnan. the nutrient situation of purple soil in sichuan basin shown that state of surface was better than subsurface, while in yuanmou of yunnan the state was on the contrary due to the degradation of surface soil
實驗室對四川內江、樂山和雲南元謀不同類型紫色土表層和亞表層微生物數量特性的比較分析表明:土壤有機質、氮磷鉀全量及其速效量均表現為表層高於亞表層,與紫色土類型和利用方式無關;三大類土壤微生物細菌、放線菌和黴菌數量均表現出表層高於亞表層,表明紫色土表層的有機質和通氣性優于亞表層,適宜於這三大類微生物生長;溫濕氣候條件下的四川盆地和乾熱氣候條件下的雲南元謀其紫色土微生物數量的剖面變化具有相同的趨勢,唯土壤營養狀況在四川盆地紫色土中表現為表層優于亞表層,而在雲南元謀紫色土中由於表層土壤的退化作用表現為亞表層優于表層的相反情況。Dithiocyanomethane is an efficient, broad - spectrum germicide and algaecide, displaying strong exterminating effects against germs, fungus and algae existing in circulating water. it maintains long - term effects and is applicable to broad ph value and temperature ranges
二硫氰基甲烷是一種高效廣譜的殺菌滅藻劑,對于循環水中存在的主要細菌真菌和藻類都具有高效的殺滅效果,而且藥效維持時間長,適應的ph值和溫度范圍較寬。Isolate all grew well in the culture medium with initial ph 4 - 10, the optimal growth temperature range was from 28 to 30. 5 degree c. it grew well on the medium for fungi growth, such as pda medium and czpek medium etc, and also grew well on the cause ' s i medium and the non - nitrogen medium, but little growth on the luria bertani medium ( lb ) and beef extract peptone medium. it did not need special nutrition factors for growth, but source of the carbon was the key factor to growth, all of its nutrition needs were different from that of common bacteria
該菌在初始ph4 - 10的培養基中都能夠生長,生長最適溫度范圍為28 - 30 . 5 ,在pda 、查氏等真菌培養基中生長旺盛,在高氏1號和無氮源培養基中同樣生長良好,而在lb與牛肉膏蛋白腖等細菌培養基中生長很差,碳源是其生長的關鍵因子,這有別於一般細菌的營養需求。Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments. the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose, sucrose, malic acid, mannitol ), propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum, at a ph range of 4 to 8. 5, at a saline concentration range of 0. 01 % to 1. 5 % ; low nlv " concentration had little effect on its nitrogenase activity. ara could also be detected when it grow in the culture media with 5mmol / l ntv "
W12菌株對環境因子的適應性研究:無氮培養條件下,測定溫度、碳源、酸堿度、滲透壓對w12生長及固氮能力的影響,結果表明,在15 - 40下均能生長並表達固氮酶活性,其最適生長及固氮的溫度為25 - 35 ;能利用葡萄糖、蔗糖、蘋果酸、甘露醇等多種碳源生長並固氮,當培養基中同時存在蔗糖和蘋果酸時,細菌生長和固氮活性最強;在偏酸和偏堿的條件下( ph4 . 5 - 8 . 5 )均能保持較強的生長勢和較高的固氮酶活性,並能通過調節自身代謝平衡並適應環境的酸、堿性變化,使培養液趨于中性:能耐受較高的滲透壓,培養液中卜、 5 naci濃度對其生長和固氮酶活性影響不大,當naci濃度升至2時,菌株的生長勢及固氮酶活性才有所下降:低濃度的鉸對其固氮酶活性影響不大,在0The percentage of autumn degradation bacteria was the biggest, it was 0. 547 %. among degradation bacteria genus, the bacillus proportion in each season was the biggest, that was 44. 44 %, 50. 00 %, 48. 15 % and 47. 22 % in spring, summer, autumn and winter respectively, other bacteria genus ' s proportion were less than bacillus. this was probably related to the basic proterties of soil, the alternation of four seasons, the change of temprature and the difference of vegetation were fairly suitable to the growth of bacillus
在土壤細菌總數上,夏季的細菌數量最多,其次分別為春、秋、冬各季;在土壤中降解氧樂果的細菌數量上,夏季土壤中的降解菌株數量也最多,其次分別為春、秋、冬各季,土壤磷的含量與降解氧樂果細菌的數量之間並沒有太大的相關性( r = 0 . 494 ) ;在降解菌占細菌總數百分比上,秋季降解菌株所佔百分比最大,為0 . 547 % ;在降解菌株中,芽孢桿菌屬( bacillus )在每一季節所佔的比例都是最大的,春、夏、秋、冬分別為44 . 44 % 、 50 . 00 % 、 48 . 15 % 、 47 . 22 % ,其它菌屬所佔比例都比較少,這可能跟土壤的基本性狀有關,春夏秋冬四季的輪換,氣溫的變化,植被的差異,耕作的不同,比較適合抗逆性較強的芽孢桿菌屬( bacillus )的生長。So some methods suitable to large plasmid extraction, including lysis by sds and a method from a literature, were used to try to extract the large plasmid from the strain cell. the lysis reactions in these two methods are gentle, so the large plasmid cannot be injured in the lysis process, opposite to lysis by alkali. it would be helpful to keep the integrality of the large plasmid during the extraction
因此我們採用了適合於大質粒提取的sds法,和文獻中應用於硝基苯降解性質粒的提取方法,來嘗試對菌株細胞進行質粒提取,這兩種方法裂解反應溫和,不會像堿裂解法那樣,在裂解過程中損壞質粒,可以實現質粒提取的完整性。The paper adopted the common breeding way by series of mutagen treating to the yeast ' s cell and spheroplast. finally, the excellent mutant 75l 3555 was obtained. its nature of the production was determined and it can product ethanol on the condition of 40 and have high fermentative speed and stable production. on the other hand, the test was made that the best fermentative condition was found. in the malt juice, adding 0. 02 % k + or 0. 03 % a13 + can increase the production strikingly and adding some degree concentration trahalose can increase the production too and cut short the time of taming. in the study of using molasses producting ethanol, we can obtain high productivity contained the following composition : nitrogen source 1. 5 % maize and 0. 075 % ( nh4 ) 2so4
