中文拼音 [xiāohuàsùlǜ]
硝化速率
英文
rate of nitrification-
The results showed that the cucumber seeds soaked with extracts of total alkaloid, dissoluble alkaloid and fat - soluble alkaloid from p. multisectum ( maxim. ) bobr., the activities of amylase, protease and lipase during seed germination were inhibited, the seed vigor and germination rate were suppressed, and respiration rate of seedling was slackened ; root activity, chlorophyll content and activities of nitrate reductase, superoxide dismutase sod ) and peroxidase ( pod ) of cucumber seedlings during seedlings growth were increased
結果表明,多裂駱駝蓬總生物堿提取液、水溶性生物堿提取液和脂溶性生物堿提取液浸種均抑制黃瓜種子萌發過程中澱粉酶、蛋白酶和脂肪酶活性,種子活力和萌發速率降低,呼吸速率減慢;幼苗生長過程中根系活力、硝酸還原酶活性升高,葉綠素含量增加,超氧化物歧化酶( sod )和過氧化物酶( pod )活性提高。These enzymes are significant as a digestive aid to larval fish, improving survival and enhancing growth. sick and stressed fish are also beneficiaries of these enzymes. genchem polytase is our top of the line product, genchem polytase is a compound of several enzymes, rhizoma coptidis and cortex phellodendri extracts which can speedily and safely dissolve left - over feed, thus solving the problem of sediment formation and the stress caused by nitrous or ammonia
維生消化素也是消化整腸酵素,經由多種酵素及黃蓮,黃柏抽出物的綜合體,因為是多種酵素的組合所以能迅速分解殘餌,完全解決污泥的產生,免除亞硝酸及阿摩尼亞所造成的緊迫甚至泛池,更因為神奇的酵素作用能預防及免除使擾亂幼蝦正常代謝的生化與營養變化物質,而獲得幫助蝦苗消化酵素分化的正常機能,提高飼料效率,增加存活率防止疾病。The paper summarize some relevant data and introduces the current research situation about the offects of intragen on photosynthesis, chlorophyll, photosynthetic rate, effeciency of solar energy utilization, dark reaction and photorespiration etc., on respiration and on some metabolic enzymes, including nitrate reductase, enzyme protective system of membrane - lipid peroxidation
綜合國內外有關文獻,介紹了氮素對植物光合作用(包括光合色素、光合速率、光能利用率、光合暗反應、光呼吸等) 、呼吸作用和一些代謝酶(包括硝酸還原酶、膜脂過氧化酶促防禦系統)的影響。Chemolithoautotrophic nitrifying bacteria have many unfavorable physiological characteristics, namely, slow growth, small biomass and susceptible to environmental factors. to remove high ammonia - nitrogen concentration in wastewater from refineries, we directly enriched nitrifying bacteria of activated sludge via optimizing enrichment conditions ( temperature > phu nh4 + - n concentration ). the results showed that the number of nitrifying bacteria after 6 weeks enrichment increased 32. 8 times and nitrification rate improved 2. 76 times than that before enrichment
實驗結果表明,在ph7 . 7 8 . 5 、 28 , 150rpm振蕩暗培養的條件下,通過不斷添加富集培養基,經過6周的培養后,可以使硝化細菌的數量增加32 . 8倍,硝化速率提高2 . 76倍,達到了富集的目的。分享友人
