麩皮培養基 的英文怎麼說
中文拼音 [fūpípéiyǎngjī]
麩皮培養基
英文
bran mash-
The xylanase activity of the mutant kept stable after 10 generations. after orthogonal designing experiment, the optimum fermentation conditions of a. niger j 506 were obtained, which is as followed : concentration of the major carbon resource 4 %, ratio between bran and corncob 5 : 5, concentration of glucose 0. 1 %, concentration of ammonium oxalate as supplemental nitrogen resource 2. 0 %, the initial ph of liquid medium 5. 0, 100ml / 250ml flask
經過正交試驗設計，得出突變株a . nigerj506產木聚糖酶最佳的工藝條件為：主碳源濃度4 、麩皮與玉米芯的比例為5 ： 5 、輔加碳源葡萄糖的濃度是0 . 1 、輔加氮源草酸銨的濃度是2 . 0 ，培養基初始ph為5 . 0 ， 250ml三角瓶的裝液量為100ml 。The optimum conditions in wheat bran and rice bran on solid state fermentation were 3 % corn starch as additional carbon sources, 4 % ( nh4 ) 2 so4 as additional nitrogen sources, 60 % moisture content of the medium, 25
在麩皮米糠培養基中，添加3的玉米澱粉、 4的（ nh _ 4 ） _ 2804可顯著提高固體曲中植酸酶酶活，培養基最佳含水量為60 ；最佳產酶溫度為25 。The results showed : the best additive water to wheat bran solid medium was 35 percent. a. niger an01001 produced high activity phytase when it was cultivated at 30 ? from 90 to 120 hours, and obtained the highest enzyme activity at 114 hours. phytase activity was effected by different buffer and ph, enzyme activity was high at ph 5. 5 and 6
對該菌的產酶條件進行研究的結果表明：麩皮固體培養基的最適加水量為35 ； 30培養90 120h之間產酶都比較高，在114h酶活最高；在提取時不僅ph對酶得率有影響，而且不同提取液所要求的最適ph也不同，用乙酸緩沖液提取時，當ph為5 . 5 、 6 . 5時酶活較高，進行水提取時，在ph7 . 5時酶活最高；利用cacl _ 2溶液進行提取的濃度達到3時，酶活最高。Solid state medium was optimized through orthogonal experiment. the suitable medium contained ( g / kg dry solid material ) : water 600, brown sugar 7, rice bran 420, wheat bran 580
通過正交實驗得出較適合的固態培養基為：每千克固體物料中含米糠420g 、麩皮580g 、紅糖7g ，含水量為固體物料干重的60 。分享友人
