【預期用途】
尼古丁(Nicotine)是煙草中的主要生物堿,是導致吸煙成癮的物質動因,也是評價人體攝入煙草煙霧的常用指標。但因為尼古丁半衰期短,無法作為標志物檢測,其代謝物可替寧因為半衰期長作為吸煙和戒煙的標志物。
本品采用競爭抑制法和膠體金免疫層析技術,用于快速定性檢測人體唾液中的可替寧,適用于評價煙草煙霧攝入的初步篩查。

為了進一步提細菌產量,研究人員將GPPS和PS基因進行了融合,進行GPPS-PS重組蛋白的融合表達。結果蒎烯的產量達到32 mg/L,是先前報道大腸桿菌的6倍。
雖然重組菌生產蒎烯的量得到了顯著提細菌,但還無法真正對JP-10構成挑戰,為了能與JP-10形成競爭,科研人員必須將蒎烯的產量提細菌26倍。事實上,這個目標并非不可能,因為這個產量在大腸桿菌的能力范圍之內。因此,科學家們相信,他們已經克服了達到這一目標過程中必須解決的一個主要障礙。
此外,研究人員還發現一個問題,酶會被底物所抑制,而且抑制具有濃度依賴性。要解決這個問題,或者使用不會被細菌濃度底物抑制的酶,或者建立能保持低底物濃度的方法,雖然這兩個途徑都比較困難,但并非是不可克服。
在20世紀,化石燃料支撐著整個工業生產的發展,但化石燃料難以長期維持整個世界的經濟發展。據估計,石油資源將在未來100年左右達到枯竭,在未來的10~20年內,石油將出現嚴重的供不應求的局面。此外,大量化石燃料的使用也帶來了嚴重的氣候問題。化石燃料中碳元素zui終以CO2的形式進入大氣,從而產生大理溫室氣體。
微生物燃料電池(Microbial fuel cell,MFC)是一種產生電能的新方法,利用微生物將有機物中的化學能轉變成電能。1911年,英國科學家*發現細菌培養液能夠產生電流,利用鉑作為電極,將其放進大腸桿菌和酵母菌的培養液中,成功制作出世界上*個MFC。不過微生物燃料電池是一項新興技術,沒有大規模應用,還需要很長一段時間才能走向成熟。
產電微生物的篩選是建立MFC很重要的一個環節,目前,在自然條件下分離的產電微生物主要是變形菌門(Proteobacteria)和厚壁菌門(Firmicutes)的細菌,多為兼性厭氧菌,可氧化糖類、有機酸等獲得能量維持生長。

In order to further raise the bacterial yield, the researchers fused GPPS and PS genes and performed the fusion expression of GPPS-PS recombinant protein. Results The yield of pinene reached 32 mg / L, which was six times higher than previously reported E. coli.
Although the amount of pinene produced by recombinant bacteria is significantly increased by bacteria, it can not really pose a challenge to JP-10. To compete with JP-10, researchers must increase the yield of pinene 26 times. In fact, this goal is not impossible, because the yield is within the capabilities of E. coli. As a result, scientists believe they have overcome one of the major obstacles that must be addressed in achieving this goal.
In addition, researchers also found a problem that the enzyme is inhibited by the substrate and that the concentration is inhibited in a concentration-dependent manner. To solve this problem, either using an enzyme that is not inhibited by bacterial substrate concentration or establishing a method that maintains a low substrate concentration, while both are difficult, it is not insurmountable.
In the 20th century, fossil fuels supported the development of the entire industrial production, but it was difficult for fossil fuels to sustain the economic development of the entire world for a long period of time. It is estimated that oil resources will be depleted in the next 100 years or so and there will be a serious shortage of oil in the next 10 to 20 years. In addition, the use of large amounts of fossil fuels poses serious climate problems. Carbon in fossil fuels ultimay enters the atmosphere as CO2, creating Dali's greenhouse gases.
Microbial fuel cell (MFC) is a new method of generating electrical energy, using microorganisms to convert chemical energy in organic matter into electrical energy. In 1911, for the first time, British scientists found that bacterial culture fluid can generate electric current, and successfully produced the first MFC in the world by using platinum as an electrode and putting it into the culture solution of Escherichia coli and yeast. However, microbial fuel cell is a new technology, there is no large-scale application, it will take a long time to mature.
The selection of electroporation microorganisms is a very important step in the establishment of MFC. At present, the electrogenic microorganisms isolated under natural conditions are mainly Proteobacteria and Firmicutes bacteria, mostly facultative anaerobic Bacteria, oxidizable sugars, organic acids and other energy to maintain growth.
