Microbiology Week 1

    Microbiology is the study of small organisms that can't be seen by our naked eyes.Microbiology is the study of microscopic organisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cell). Microbiology encompasses numerous sub-disciplines including virology, mycology, parasitology and bacteriology. Microbiology are divided into seven types which are bacteria, archaea, protozoa, algae, fungi, viruses, and multicellular animal parasites (helminths). Each type has a characteristic cellular composition, morphology, mean of locomotion and reproduction. Microorganism are beneficial in producing oxygen, decomposing organic material, providing nutrients for plant and maintaining human health but some can be pathogenic and cause diseases in plant and humans.

    Applications of microbiology are Medical Microbiology  is the study of pathogenic microbes and the role of microbes in human illness. This includes the study of microbial pathogenesis and epidermiology and is related to study of disease pathology and immunology. Beside that, Pharmaceutical Microbiology  is the study of microorganism that are related to the production of antibiotics, enzymes, vitamins,vaccines, and other pharmaceutical products. Moreover, Microbial Biotechnology is the manipulation of microorganism at the genetic and molecular level to generate useful products. Furthermore, Food Microbiology is the study microorganism causing food spoilage. Microbiology can produce foods for example fermentation.Next, Agricultural Microbiology is the study of agriculturally relevent microorganism.

    Lastly, Thiomargarita namibiensis is the largest bacteria in the world and is a gram negative coccoid Proteobacterium, found in the ocean sediments of the continental shelf of Namibia. Thiomargarita means " sulfur pearl". This refers to the appearance of the cells; they contain microscopic sulfur granules that scatter incident light, lending the cell a pearly lustre. Namibiensis means of Namibia. Mycoplasma genitalium is the smallest bacteria and is the parasite bacterium which lives in the primate bladder, waste disposal organs, genital and respiratory tracts, is thought to be smallest known organism capable of independent growth and reproduction.
