The main research contents and results are as follows : ( 1 ) disc papers and oxford cups were used to ascertain bacteriostatic effect of hongqu . using 70 % ethanol and water as solvent , the extraction inhibited bacillus subtilis , bacillus cereus and staphylococcus aureus and had no effect on e . coli , salmonella . typhi , yeasts and algae 主要研究內容和結果如下: ( 1 )利用濾紙片法和管碟法確定了紅曲的抑菌譜:紅曲70乙醇和水溶液浸提物對蠟樣芽孢桿菌、枯草芽孢桿菌等革蘭氏陽性菌具有較強的抑制作用,對革蘭氏陰性菌、霉菌和酵母菌沒有抑制效果。

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、北京棒狀桿菌和霉菌中的綠色木霉、黃曲霉有明顯的抑菌作用;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、靈桿菌和霉菌中的綠色木霉以及黃曲霉有明顯的抑菌作用,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。

Culture supernatants of bt strains induced luminescence in v . harveyi reporter strain bb170 , which can only response to ai - 2 signal moleculars , indicating that the bt strains have the luxs gene . by aligning the nucleotide sequences of the b . anthracis and b . cereus luxs genes , a pair of primers were designed and an 474 - bp fragment was amplified from bt strains by pcr 首先通過生物發光實驗檢測到蘇云金芽孢桿菌( bacillusthuringiensis , bt )的培養液可以誘導特異性檢測ai - 2信號分子的哈氏弧菌報告菌株bb170發光,表明bt中含有群體感應信號分子ai - 2的合成基因luxs 。

The strain and its metabolites are identified . the results show that the culture has a broad antimicrobial spectrum against some gram - negative and gram - positive bacteria , and moulds , especially against e . coli , bacillus cereus , and staphylococcus aureus 研究證實,分離出的r21 - 4具有廣譜抗菌作用,對革蘭氏陰性菌、革蘭氏陽性菌、真菌都有一定的拮抗作用,特別是對大腸桿菌、金黃色葡萄球菌、蠟狀芽孢桿菌抗菌作用較強。

Objective in order to look for the effective microecological bacteria for the different microbial preparation and feed additive , we investigated the differences of amylase between bacillus licheniformis , bacillus subtilis , bacillus cereus , and bacillus natto 摘要目的探索常見4種微生態制劑菌種地衣芽胞桿菌、枯草芽胞桿菌、蠟樣芽胞桿菌和納豆芽胞桿菌產生淀粉酶的能力,以篩選和研制動物微生態制劑和飼料添加劑的使用菌種。

Detection of distribution of aii gene and aii protein in bacillus species and b . thuringiensis subspecies indicated that except for b . thuringiensis and b . cereus strains , b . subtilis and b . sphaericus strains had lower aii activity , but b . megalerium strain had no activity at all 用pcr方法也檢測到,在上述四種細菌中存在aii基因。而巨大芽胞桿菌的培養物沒有aii活性, southern雜交結果表明無aii基因的存在。

The 7 isolates were identified based on physiological and biochemical characterization , 16s rdna sequence , g + c mol % and dna - dna hybridization . isolate tl was identified as bacillus cereus . isolate gl , c4 and c5 were identified as bacillus megaterium 在上述試驗的基礎上,本文分別用生理生化性狀、全細胞脂肪酸成分分析、 16srdna序列分析及dna - dna雜交實驗對這7個含有nifh的菌株進行了鑒定。

The results were unambiguous : two minutes of microwaing on full power mode killed or inactiated more than 99 percent of all the liing pathogens in the sponges and pads , although the bacillus cereus spores required four minutes for total inactiation 結果是非常明了的:在高能量模式下經過兩分中微波可以殺死或者滅活99以上的所有在海綿和洗滌墊中的病原體,盡管蠟樣芽胞桿菌總體滅活時間需要4分鐘。

Three dominant strains of bacteria in clay soil were obtained by the screening experiments , which were acinetobacter icoaceticus - baumanni c0 / / ex ( nya2 ) , bacillus megaterium ( nyb ) and bacillus cereus ( nyb4 ) 試驗篩選了對精喹禾靈具有降解作用的優勢菌株nya2 (鮑氏不動桿菌acinetobacterlcoaceticus - baumannicomplex ) 、 nyb1 (巨大芽孢桿菌bacillusmegaterium ) nyb4 (堅實芽孢桿菌bacilluscereus ) 3個。

The relation of the heat output rate with original replion is or / 1030 ) or / 44 ) or / 2062 . the heat output indicated that different promoter had various impact on the expression of gfp . the drive impact was promoter btl - btll } promoter b . cereus ) promoter cry3a Pcr擴增結果顯示均可從兩株標記基因工程菌中得到肺片段,且還可以從ybti765一74中擴增出犯t一1765中沒有的c盡] acjo基因。

Aps , found by prof . pei yan , et al , is a novel antifungal peptide isolated from bacillus cereus s - l . it has been reported that in the presence of aps , hypha growth and spore germination of several phytopathogenic fungi in agriculture were strongly inhibited Aps是西南農業大學裴炎教授等發現的由蠟狀芽孢桿菌s - 1分泌的一種抗真菌多肽,對多種農作物病原真菌有較強抑制作用。

I can still fantasize about watching a night - blooming cereus unfold , something i ' ve always wanted to do , or about meeting one of my favorite celebrities , or even of losing a few pounds 我仍然能夠幻想著觀看一個夜間開花的仙人掌展現在我面前,幻想著我要去做的某件事情,幻想著遇到我最喜歡的名人,或甚至夢想丟掉幾英鎊的錢。

The researchers also found that microwaes were effectie in decontaminating syringes , but that it generally took far longer , up to 12 minutes for bacillus cereus spores 研究者還發現了微波對于凈化注射器是很有效果的,但是那通常需要較長時間,大概12分鐘來殺死蠟樣芽胞桿菌的孢子。

Results all bacteria we investigated could produce varying level amylase , the highest activity of amylase was from the bacillus cereus 結果地衣芽胞桿菌、枯草芽胞桿菌、蠟樣芽胞桿菌和納豆芽胞桿菌都能產生淀粉酶,以蠟樣芽胞桿菌產生的淀粉酶較多。
