中文拼音 [ǎnxìjūn]
銨細菌
英文
ammonium bacteria-
The cell extract aliquots were added by ammonium sulfate with 30 %, 40 %, 50 %, 60 %, 70 %, 80 % and 90 % saturation, separately. the activities of sod for the re - suspensions were detected after dialysis and centrifugation. it was found sod activity could be detected after the precipitation by ammonium sulfates with 30 % saturation or above, and the highest sod activity could be obtained by precipitation of ammonium sulfate with 80 % saturation
Maltophilia276菌株細胞提取物中分別加入飽和度為30 、 40 、 50 、 60 、 70 ， 、 80和90的硫酸銨，經過透析、離心、重新懸浮后檢測sod的活性發現：當硫酸銨的飽和度為30時，其活性可檢測出sod活性，當硫酸銨的飽和度為80時，檢測出的sod活性最大。Two protein peaks can be obtained by bio - gel p - 6 chromatography and both peaks have antimicrobial activity. so the bacteriocin is consisted of two proteins with different mw. only one protein with larger mw can be detected through tricine - sds - page, and its mw is about 8, 570da
採用30硫酸銨就能完全把發酵液中的細菌素全部沉澱，通過生物膠bio - gelp - 6層析發現細菌素被分離出兩條抗菌蛋白峰，這表明r21 - 4產生的細菌素是由兩種不同分子量的蛋白質組成的，通過tricine - sds - page檢測，只能檢測到一條分子量相對較大的細菌素，分子量在8 ， 570da左右。It is a bactericidal antibiotic which is resistant to most b - lastamases and is active against a wide range of gram - positive and gram - negative organism
它是一種抗菌素，不但能抵抗大多數b內酰銨酶，而且抵抗各種革蘭氏陽性和革蘭氏陰性細菌。Results indicated that the concentration of salvolatile and the conserved effect was in proportion because of the capability to counteract the acids produced by microbe
實驗結果表明，濃度越高的碳酸銨鹽溶液的保存體系，其緩沖能力越大，越能很好地中和細菌代謝產生的脂肪酸，以防止天然膠乳的迅速凝固，保存效果越好。分享友人
