從污染環(huán)境中篩選提純降解氯乙烯類污染物的菌株Dehalococcoides mccartyi strain 11a
|
|||
|
生物修復(fù)是迄今為止最佳的處理含有氯乙烯類污染物的工業(yè)廢水,修復(fù)土壤的可持續(xù)性方案。很多人難以捕捉到這項技術(shù)的核心。成功的關(guān)鍵不是篩選菌株,而是找到準(zhǔn)確的污染點。那里的污泥一定“藏龍臥虎”。那里的污泥中的微生物就是提純dehalococcoides 的好地方。純菌株dehalococcoides mccartyi strain 11a 對氯乙烯類有機(jī)溶劑和二氯乙烷展現(xiàn)出了高效快速的降解特性,被認(rèn)為是生物修復(fù)含有氯乙烯類有機(jī)溶劑污染環(huán)境的最有潛力的冠軍菌株。下文即將講述它的降解技能和提純經(jīng)歷,以供同行參考 (附件pdf有詳細(xì)的介紹,菌株的降解機(jī)理,純化過程等,對于正在或即將,從事利用微生物技術(shù)去除有毒難降解的有機(jī)物是一個很好的借鑒)。 abstract: this article relates to the bioremediation of persistent chlorinated ethenes including trichloroethe, dichloroethenes, vinyl chloride, and 1,2-dichloroethane in heavily polluted water and soil environment, particularly by a novel microorganism belonging to dehalococcoides species in a rapid rate. key words: bioremediation, bioaugmention, dehalococcoides, reductive dehalogenation, organohalide respiration, trichloroethene (tce), dichloroethenes (dces), vinyl chloride (vc). note: dehalococcoides mccartyi strain strain 11a and dehalococcoides mccartyi strain geo are interchangeable and they may have similar function. 作者: dr. chengdan (程丹); 職位:senior research fellow; 工作單位: scelse, nanyang technological university, singapore;[ Last edited by 小冀- on 2019-8-1 at 13:11 ] |

另外一篇關(guān)于Dehalococcoides mccartyi strain GEO12的碩士論文,比較詳細(xì)的闡明了Dehalococcoides mccartyi strains GEO12的特性。 有興趣的同行可以直接站內(nèi)回復(fù);蛘吲cDr. Chengdan聯(lián)系。Dr. Chengdan(程丹)email: g0500001@gmail.com |

Dr Chengdan (程丹)再補(bǔ)充: Difference between Dehalococcoides mccaryti strains 11a and GEO12 is the amount of carcinogenic intermediate, VC during the dechlorination of TCE. Strain 11a has minimal VC accumulation, however, strain GEO12 may have the risk of VC accumulation if dechlorination process could not be completed. Note: Dehalococcoides mccaryti strain 11a and Dehalococcoides mccaryti srains GEO are interchangeable. If you have any interests, please directly contact with Dr. Chengdan.
