Sugar Fermentation Tests The media are prepared from Coignet's gold medal gelatin in a manner similar to that described for the liquefaction test. Instead of sheet gelatin, Difco nutrient gelatin in about double strength poured out to form sheets can also be used with equally satisfactory results. After formolization the gelatin sheets are cut or punched into shapes, about 15 mm. diameter, conv...

Liwa Botanical Gardens is an ex-situ conservation area for various types of plants. Each plant produces organic matter that will provide nutrients the growth nitrogen-fixing bacteria. This indicates existence environment supports Nitrogen one needed by plants their growth. However, abundance nitrogen in atmosphere cannot be utilized directly but needs to transform into ammonium and nitrate firs...

The synthesis of water-soluble nitrogen-doped carbon dots has received great attention, due to their wide applications in oxygen reduction reaction, cell imaging, sensors, and drug delivery. Herein, nitrogen-doped, carbon-rich, highly photoluminescent carbon dots have been synthesized for the first time from ammonium citrate under hydrothermal conditions. The obtained nitrogen-doped carbon dots...

Recyclability is an important aspect for heterogeneous photo-catalysts. Ease of recovery and stability of the photo-catalyst in terms of efficiency over the number of cycles are highly desired and in fact it is ideal if the efficiency is constant and it should not decrease marginally with each cycle. Presented here is a seminal observation in which the photocatalytic activity is shown to improv...

Detection of specific antibodies would be a useful test strategy for bovine tuberculosis (bTB) as complement to the single skin test. We developed lateral flow immunochromatography (LFIC) rapid bTB detection based on use conjugate gold nanoparticles with recombinant G protein. After evaluating 3 Mycobacterium bovis (MB) antigens: ESAT-6, CFP-10 and MPB83 control line, we selected given it was m...

Silver chromate (Ag2CrO4) photocatalysts are prepared by microemulsion, precipitation, and hydrothermal methods, in order to investigate the effect of preparation methods on the structure and the visible-light photocatalytic activity. It is found that the photocatalytic activity of the prepared Ag2CrO4was highly dependent on the preparation methods. The sample prepared by microemulsion method e...
