中文拼音 [shǎijiékàng]
色拮抗
英文
rivalry of colors-
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。The anti - pathogenic activities of capsaicin, which was extracted from the chosen hot pepper, against three pathogenic bacteria and seven pathogenic fungi were evaluated
摘要從紅辣椒中提取的辣椒堿對金黃色葡萄球菌、大腸桿菌、枯草芽孢桿菌這3種常見的病原細菌及黑麴黴、啤酒酵母等7種病原真菌進行拮抗試驗。And the two pah ' s of pcr primers that bind to the adapter and the sequence of f fragment close by tn5 respectively were also designed. the genomic dna of b8 was isolated, digested with bamh i, and ligated to the adapter. using the two pairs of the primers, two rounds of pcr were performed hi turn and a fragment of 239bp was amplified successfully. lt was proved by cloning and sequencing that 18bp of the fragment is the sequence opposite to f fragment on the left of tn5 insertion site in b8f, the other is part of the 728 bp of f fragment. this result makes it possible to continue to carry out chromosome walking, to clone and sequence the whole genes of b fragment and f fragment, and to reveal the antagonistic molecular mechanism of b8
試驗研究設計併合成了由40和44個堿基的寡聚脫氧核苷酸組成的染色體爬行接頭，在接頭序列和測定的f片段近tn5的序列上，設計了2對染色體爬行用的pcr引物，從b8菌株中提取基因組dna ， bamhi酶切，與染色體爬行接頭連接，依次用2對引物進行pcr ，擴增出239bp產物，經克隆、測序，發現其中18bp為擴增的相應于f片段在b8f菌株tn5插入位點對面的序列，其餘則為f片段728bp序列的一部分，為進一步進行染色體爬行，克隆和測定整個b和f基因，揭示陽菌株的拮抗分子機制提供了技術資料貯備。
