尼古丁戒烟比赛检测试剂盒
本品采用竞争抑制法和胶体金免疫层析技术,用于定性检测人体尿液中尼古丁,适用于尼古丁药物滥用的初步筛查。
【检验结果的解释】
阳性(+):仅在控制区(C)出现一条紫红色条带,在检测区(T)无紫红色条带出现。阳性结果表明尿液中的尼古丁浓度在阈值(300ng/mL)以上。
阴性(-):出现两条紫红色条带。一条位于检测区(T),另一条位于控制区(C)。阴性结果表明尿液中的尼古丁浓度在阈值(300ng/mL)以下。
无效:控制区(C)未出现紫红色条带。表明操作不当或试剂盒已失效。在此情况下,应再次仔细阅读说明书,并用新的试剂盒重新测试。如果问题仍然存在,应立即停止使用此批号产品,并与当地供应商。
注意:检测区(T)紫红色条带可呈现颜色深浅的现象。但是,在规定的观察时间内,不论该色带颜色深浅,即使只有非常弱的色带也应判定为阴性结果。
1、希瓦氏菌
希瓦氏菌(Shewanella)属是研究较多的产电微生物,主要有S. putrefactions IR-1、S. oneidensis DSP10和S. oneidensis MR-1,它们都属于变形菌门,交替单胞菌目(Alteromonadales),希瓦氏菌科。革兰氏阴性杆状,兼性厌氧。有氧条件下,可*氧化丙酮酸、乳酸为CO2。厌氧条件下,以乳酸、甲酸、丙酮酸、氨基酸、氧气为电子供体。
S. oneidensis DSP10是zui早发现的可在有氧条件下产电的细菌,在有氧条件下能将乳酸氧化成CO2产电,该菌还能以葡萄糖、果糖、抗坏血酸(维生素C)为电子供体产电,以果糖为电子供体时产电zui细菌,功率密度达350W/m2。该菌在微生物燃料电池中有较好的应用前景。
S. putrefactions IR-1zui初是从稻田土中分离到,是*报道的能直接将电子传递到电极表面的产电菌,开创了无介体燃料电池的研究先河。S. oneidensis MR-1多用于细胞与电极间电子传递机制的研究,其全基因组序列已完成,研究发现S. oneidemisMR-1约有37个编码Cytc的基因,Cytc被认为是电子跨膜传递的通道。
2、铁还原红育菌
铁还原红育菌(R. ferrireducens)属于变形菌门,伯克氏菌目(Burkholderiales),丛毛单胞菌科(Comamonadaceae),红育菌属(Rhodoferax)。革兰氏阴性,兼性厌氧,可以*氧化葡萄糖、果糖、木糖、庶糖等生成CO2。该菌是zui早报道能直接*氧化葡萄糖产电的微生物,其它多数铁还原菌电子供体局限于简单有机酸,如乙酸、乳酸等。当向MFC加入糖或其它较复杂的有机物作为燃料时,还需要发酵细菌将其降解为简单有机酸后才能被利用。R. ferrireducens能以电极为*电子受体直接氧化葡萄糖、果糖、庶糖、木糖等生成CO2,并从电子传递中获得生长所需的能量。以葡萄糖为电子供体时,R. ferrireducens的电子回收率达81%。R. ferrireducenszui适生长温度为25℃,但在4℃下仍能生长并还原Fe。由该菌构建的微生物燃料电池具有蓄电池的特点,利用底物产电迅速,放电后补充底物可恢复原来产电水平,可反复充放电,电池性能稳定。

1, Shewanella
Shewanella is a genus of more electrogenic microorganisms, mainly S. putrefactions IR-1, S. oneidensis DSP10 and S. oneidensis MR-1, which belong to Proteobacteria, Alteromonadales, Shewanellaceae. Gram-negative rod, facultative anaerobic. Under aerobic conditions, pyruvate can be compley oxidized, with lactic acid as CO2. Anaerobic conditions, to lactic acid, formic acid, pyruvic acid, amino acids, oxygen as electron donor.
S. oneidensis DSP10 is the earliest discovered bacterium capable of producing electricity under aerobic conditions and capable of oxidizing lactic acid to CO 2 production under aerobic conditions. The bacteria can also use glucose, fructose and ascorbic acid (vitamin C) as an electron donor Body electricity, to fructose when the donor for electron donor bacteria, power density of 350W / m2. The bacteria in microbial fuel cells have a better prospect.
S. putrefactions IR-1 was first isolated from paddy soils and was the first reported electroporation bacterium to transfer electrons directly to the surface of electrodes. It pioneered the research of a dielectric-free fuel cell. S. oneidensis MR-1 is mainly used to study the mechanism of electron transfer between cells and electrodes. The genome-wide sequence of S. oneidensis MR-1 has been completed. About 37 genes encoding Cytc were found in S. oneidemis MR-1 and Cytc was considered as transmembrane aisle.
2, red iron reduction bacteria
R. ferrireducens belongs to the genera Proteobacteria, Burkholderiales, Comamonadaceae and Rhodoferax. Gram-negative, facultative anaerobic, can be compley oxidized glucose, fructose, xylose, sugar and other sucrose to generate CO2. The bacteria are the earliest reports of direct and complete glucose oxidation of microorganisms, most of the other iron-reducing electron donor limited to simple organic acids, such as acetic acid, lactic acid and so on. When adding sugar or other more complex organics to the MFC as fuel, it is also necessary for the fermenting bacteria to degrade it to a simple organic acid before it can be used. R. ferrireducens can directly oxidize glucose, fructose, sucrose, xylose, etc. with the electrode as the sole electron acceptor to generate CO2 and obtain the energy required for growth from the electron transfer. With glucose as an electron donor, the electron recovery of R. ferrireducens was 81%. R. ferrireducens optimum growth temperature of 25 ℃, but at 4 ℃ can still grow and restore Fe. The microbial fuel cell constructed by the bacterium has the characteristics of a storage battery. The substrate can be rapidly used to generate electricity. After being discharged, the supplemental substrate can restore the original production level and can be repeatedly charged and discharged. The performance of the battery is stable.
