the earth‚ there are so many places that are so extreme that we thought that no living things could adapt to the environment. Interestingly‚ there are some organisms that can inhabit in extreme environments‚ and they are extremeophiles‚ which are microbes that can thrive and adapt under extreme conditions. There are many types of extreme environment‚ such as extremely cold or hot‚ too acidic‚ lacking of water or light‚ and more. One of the examples of extreme environment is Lake Vostok in Antarctica

Germs and Steel‚ author Jarred Diamond visited human history covering over one million years. In nineteen chapters‚ he explained the human evolution from hunter gatherers to modern humans along with vast food production‚ plant and animal domestication‚ battles and illnesses that ruled the Earth. According to Diamond‚ world advanced from the hunter gatherers to modern humans at different rates and it was all connected to the domestication and food production (or guns‚ germs and steel). The world’s

supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus‚ identification of microbes is a process of elimination based on logic and carefully-performed tests to determine the capabilities of the unknown microbe. The pieces of evidence used in the microbiology lab are your observations of the shape‚ morphology‚ Gram reaction‚ and the results from

However‚ they have been an attractive source of study for many scientists‚ since they live in all parts of biosphere and are critical to nutrient recycling in ecosystems. Microbes in general are described as one of the most remarkable existence. «The procaryotes in particular are by very large margin the most biochemically and genetically diverse organisms on earth» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚

Quats work by denuturing the protein of the bacterial or fungal cell‚ affecting the metabolic reaction of the cell and causing vital substances to leak out of the cell causing death. Which microbes are most susceptible versus most resistant to disinfectants? Why?Gram-positive cocci‚ including antibiotic-resistant staphylococci‚ are readily inactivated by disinfectants. Enterococci‚ including vancomycin-resistant strains‚ are also susceptible

While microbes are often viewed negatively due to their association with many human illnesses‚ microbes are also responsible for many beneficial processes such as industrial fermentation (e.g. the production of alcohol and dairy products)‚ antibiotic production and as vehicles for cloning in higher organisms such as plants. Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase‚ reporter genes for use in other genetic systems

Soil samples are highly rich in microorganisms. The antimicrobial activities of microbes from 3 different soil sources (Tenby‚ Summerstrand‚ North Campus main building round-about and South Campus water pond) will be tested. Pure colonies isolated from the microbes will be tested for antimicrobial activity against known microorganisms

Although bioremediation is primarily established my man‚ it is a fairly natural process using microbes that occur naturally in nature to clean up any unwanted contaminants. C.
