sediment beneath the lake exceeds 250 metres (820 ft), according to a Bureau of Mineral Resources Canberra drilling programme in the 1982/83 summer. The oldest sediments, which lie some distance above the bedrock, were dated at 3–5 million years using spore and pollen analysis and magnetic…

and can be found in intestines mainly but also, breast milk and the vaginal area. The amount of Bifidobacterium Bifidum in your system can be increased by taking certain probiotics. Bifidobacterium Bifidum is Gram-positive. Its rod-shaped, non- spore forming and it is anaerobic and therefore, found in low oxygen areas. These pathogens can live independently or in clusters. Bifidobacterium Bifidum aids in digestion…

Meiosis- A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. I have heard a lot about mitosis but not enough about meiosis. 5. Heterozygous-having dissimilar pairs of genes for any hereditary characteristic.Heterozygosity occurs when an individual has two different alleles of a gene. I've never heard of…

required by C. difficile to make proteins and then there is “Amixicile” which targets an enzyme found in anaerobic bacteria, like in C. difficile. The NIAID is supporting research that focuses on understanding basic mechanisms of C. difficile spore-formation and spore germination and also the spread within health care facilities. The major difference between C. difficile is that usually you contract it from antibiotic use. It is really tough to tell the difference from C. difficile to other…

made by the burning of fossil fuels. Fossil fuels are natural fuels such as coal or gas. They are formed in the geological past from the remains of living organisms. Natural gas moved in between the cracks and spaces of overlaying rocks and is tiny spores(spaces) of rocks when the fossil fuels decayed. Geologists locate the types of rocks that are likely to natural gas deposits. Some of these rocks can be found on land while others are located on the ocean floor. Once they find these rocks,…

Fecal microbiota transplantation is a technique whereby fecal matter from a donor is utilized. Family members, or significant others who live in the same or close to the same environment that the patient lives in are selected, however, there have been successful transplant cases where an unrelated donor has been selected. Exclusion criteria include antibiotic therapy taken within the last three months before donation to ensure complete microbiome recovery and all donors are tested for…

Bioterrorism is the release of toxic biological agents with the intent of harming others. Due to scientific advancements over the years, the threat of bioterrorism has tremendously grown. Scientific advancements have made it easier to manipulate agents to withstand harsh environments and to manipulate various agents into different physical forms. An attack of this kind can not only harm humans, but it can also have a negative impact on agriculture and livestock. Without these vital food sources,…

informally as a Lactic Acid Bacterium because it ferments milk sugar (lactose) to lactic acid. Lactococci are typically spherical or ovoid cells, about 1.2µm by 1.5µm, occurring in pairs and short chains. They are Gram-positive, non motile, and do not form spores. Lactococci are found associated with plant material, mainly grasses, from which they are easily inoculated into milk. Hence, they are found normally in milk and may be a natural cause of souring. Lactococcus lactis has two subspecies,…

Escherichia Coli, or E. Coli, are a large and diverse colony of bacteria within the fecal coliforms group – a group of closely related bacterial genera that share the ability to metabolize sugar lactose, producing acids and gas as byproducts – found living harmlessly in warm-blooded organisms’ intestines, the environment, or in various foods (2006). Unfortunately, some forms of E. Coli bacteria are pathogenic, in which the bacteria has developed the ability to cause the disease of the urinary,…

Did one single disaster cause the K-T extinctions? Some scientists and people are committed to just one reason the K-T extinctions occurred but in this paper many possibilities will be explored with evidence to back up why they could have been a cause as well to the extinctions. Everyone will ultimately make his or her own decision/thoughts on what could have happened, and of course all hypotheses would be subject to analysis. Asteroid impact theory. The impact of a 10 km+ asteroid would blow a…
