Tea Dangerous
We all know that the British love their tea. Can you imagine the uproar in the UK and amongst Brits all over the world when the British Medical Journal revealed some interesting and maybe controversial findings? Scientists discovered that drinking a steaming cup of tea can significantly spike your chances of esophageal cancer. Compared with [...]
Bacteria use poison to make food
Some bacteria from Mono Lake in California do photosynthesis the old-fashioned way — really old-fashioned: They use arsenic instead of oxygen. Arsenic photosynthesis may be an ancient form of metabolism, dating from the earliest days of life on Earth before oxygen filled the atmosphere, says Ronald Oremland, a microbiologist and geochemist with the United States [...]
Salmonella of Food Poisoning Infections
A surge of Salmonella Saintpaul illnesses in six states tied to sprouts has been linked to an earlier outbreak of the same strain of Salmonella. The vehicle appears to be the sprout seeds, used by different manufacturers. 35 people on Michigan, Minnesota, Pennsylvania, South Dakota, Utah, and West Virginia are confirmed ill in outbreak of [...]
Thermophilic Bacteria
Organisms time and again stay in spaces which give the impression unlivable. For instance, thermophilic bacteria exist in and round hot springs and deep-sea hydrothermal vents everyplace temperatures can exceed 100ºC. Prof. Oshima wondered how they can live in an ecosystem with such in height temperatures and I beg your pardon? factors determine the temperature [...]
Identification of Wastewater Organisms
Facultative Bacteria Most of the bacteria that absorb the organic material in a wastewater treatment system are facultative in nature. This means they are adaptable to survive and multiply in either anaerobic or aerobic conditions. The nature of individual bacteria is dependent upon the environment in which they live. Usually, facultative bacteria will be anaerobic [...]
Identify Anaerob Bacteria
Anaerobic bacteria are found both in the body as normal microbial flora (i.e., endogenous anaerobes) and in the environment (i.e., exogenous anaerobes). Members of the genus Clostridium cause most exogenous anaerobic infections; less frequently, Sarcina ventriculi, Fusobacterium ulcerans, Desulfovibrio desulfuricans, and Desulfomonas spp. are implicated.
Sulphate-Reducing Bacteria
The sulphate-reducing bacteria (SRB) are a large group of anaerobic organisms that play an important role in many biogeochemical processes. Not only are they of early origins in the development of the biosphere, but their mechanisms of energy metabolism shed light on the limits of life processes in the absence of oxygen. They are widely [...]
How to Identify Aerobic and Anaerobic Bacteria?
Aerobic and anaerobic bacteria can be identified by growing them in liquid culture : 1. Obligate aerobic (oxygen-needing) bacteria gather at the top of the test tube in order to absorb maximal amount of oxygen. 2. Obligate anaerobic bacteria gather at the bottom to avoid oxygen. 3. Facultative bacteria gather mostly at the top, since [...]
