2) Barritt method: test bacteria inoculated in culture medium in general, 36 + 1 ~ C cultured for 4 days, the medium 2.5ml adding a naphthol (2-na-phthol) pure alcohol solution 0.6ml, plus 40% 0.2ml potassium hydroxide solution, shaking the 2~5min positive bacteria often appear ...
The selection of a reasonable range of biochemical tests to be performed as a routine for bacterial identification and characterization is dependent upon the source of the material, the diversity of the bacteria likely to be encountered, and the aim of the investigation. The Gram staining procedure...
This test is used to identify bacteria capable of hydrolyzing urea using the enzyme urease. It is commonly used to distinguish the genus Proteus from other enteric bacteria. The hydrolysis of urea forms the weak base, ammonia, as one of its products. This weak base raises the pH of the med...
A strain of nitrogen fixing bacteria, W11, isolated from the root of sugar cane has been identificated as Pantoea agglomeras using an auto identification system for bacterium based on 96 biochemical test data. 从甘蔗根部分离的固氮菌株W11,经细菌自动鉴定系统根据96个生化试验指标,鉴定为成团泛菌。
For example, the expression levels of cathelicidins could depend on the duration of lactation, the presence of an infection, and the types of causative bacteria. BMAP-27 and BMAP-28 showed effective antibacterial activity against E. coli in standard bacterial growth media, blood serum, and whey ...

This research was carried on 92 samples from clinically mastitic cows collected from 4 different places (farms) at Sharkia governorate in Egypt and tested for the incidence of pathogenic bacteria. The prevalence of the major pathogenic bacteria were Escherichia coli, Staphylococcus aureus, Streptococcus...
aWe have argued that understanding the biochemical bases of how bacteria interact with the ocean systemat the nanometre (molecular) to millimetre scale can provide insights into globally significant biogeochemical processes 我们争辩说,了解生物化学的基地怎样细菌交互式与海洋systemat nanometre (分子) 对毫米...
bacteria in this family do have some common characteristics such as: staining gram negative, when motile they have peritrichous flagella, can thrive either with or without oxygen making them facultative anaerobes, and they can ferment (utilize) glucose for energy. A series of thirteen biochemical ...
