黴菌變色
英文
discoloration by mould-
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。Objective to induce vancomycin - resistantant s aureus in vitro and to observe the changes of coagulase gene sequences of s. aureus and its relationship with vancomycin resistance
摘要目的研究萬古黴素敏感金黃色葡萄球菌經過體外誘導變成萬古黴素中介耐藥的金黃色葡萄球菌后凝固酶基因序列有無改變。The distribution fractions of mutants with higher avermectin titer than the original had correlation with implantation dose. after ion implantation mutation there were many types of morphology of colony, we stdudied the relationship between the colony shape and the ability of yielding, found that gray and protuberant colony had the highest titer
離子注入后阿維鏈黴菌的菌落形態發生了很大的變化,其中灰色,邊緣整齊,中間突出有開裂的菌落和為灰色,邊緣波浪狀,中間突出有放射狀開裂的菌株產量較高。The results showed that the extract by etoac presented a significant effect on staphylococcus aureau 、 bacillus cereus 、 bacillus megateriurn 、 proteus species, corynebacterium pekinense 、 trichoderma viride and aspergillus flavus all of which belonged to bacteria ; the extract by n - buoh presented significant inhibitory effect on bacillus mesentericus, bacillus subtilis 、 proteus species 、 bacterium prodigious, trichoderma viride and aspergillus flavus all of which belonged to bacterium ; the inhibitory effect become stronger and stronger with the extract concentration increaseing and the water phase of the extract did not present any antimicrobial effects
結果表明,乙酸乙酯萃取物對細菌中的金黃色葡萄球菌、蠟狀芽孢桿菌、變形桿菌、巨大芽孢桿菌、北京棒狀桿菌和黴菌中的綠色木霉、黃麴黴有明顯的抑菌作用;正丁醇萃取物對細菌中的馬鈴薯芽孢桿菌、變形桿菌、枯草芽孢桿菌、靈桿菌和黴菌中的綠色木霉以及黃麴黴有明顯的抑菌作用,且提取物的抑菌作用隨濃度增大而增強,而水相則沒有抑菌活性。Wood preservatives - determination of the preventive effectiveness against sapstain fungi and mould fungi on freshly sawn timber - field test ; german version cen ts 15082 : 2005
木材防腐劑.新鋸材邊材對變色菌和黴菌的防腐有效性的S. lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation. it was speculated that dnda together with its downstream dna ( 2. 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64, while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s. lividans 1326
另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因( mel )表達方面的差異,推測dnda及其下游區域與變鉛青鏈黴菌的產孢和刺激外源黑色素基因的表達有關,而dndb和dndc則與之無關,因為la1和la2在這兩種表型上與野生型菌株無明顯差異。Additionally, hau3r gene with it own promoter was cloned into high - copy plasmid pij653 and integrative plasmid pset152, respectively. transformants of s. lividans zx1 carrying these clones were infected with hau3, respectively, but the results shown that there was no significant correlation between the copy number of hau3r gene and the level of resistance to hau3
另外,將染色體來源的攜帶自身啟動子的hau3 ~ r基因分別克隆到高拷貝和低拷貝載體上並將其導入變鉛青鏈黴菌zx1 ,在實驗條件下未發現拷貝數與抗性水平間存在顯著相關性。Then, tlc was used to purify them, and antibiotic experiments were made to define which was the main antibiotic substance. results showed, orange pigment was the major antibiotic substance, and it could inhibit bacteria, but had no effect on yeasts and algae. the diameter of the inhibition zone was directly proportional to the value of absorption of orange pigment
( 2 )利用吸附柱分離三種色素,並用tlc法純化,刮取相應的色素點, 70乙醇溶解,濃縮,進行抑菌實驗,證實橙色素是主要的抑菌物質,對細菌具有較強的抑制效果,其抑菌性與其吸光度呈正比變化,橙色素對酵母菌和黴菌無抑制效果。分享友人
