  • Importance Of Bacteria

    1337 Words  | 6 Pages

    Bacteria are unicellular prokaryotes that lack a nucleus and organelles, but they do have cell walls that contain peptidoglycan. Most bacterias are helpful and beneficial to the environment as well as to many other organisms, living in a mutualistic relationship, a close relationship in which, at most, both species will benefit. But a small number of bacteria can be pathogenic, bacteria that cause diseases, therefore harming other organisms. This trend leads to a thought that all bacteria are harmful

    Bacteria are the most successful life form on Earth. It can be found everywhere – water, soil, air, animal, human body. Though most bacteria are harmless, there are some that can cause infectious diseases. These bacterial infection range from the common ones like ear infections to serious infection such as tuberculosis. Most of these infections can be treated by taking antibiotics. Antibiotics, also referred to as antibacterial, are potent types of drug that kills or prevent the growth of infection

  • Endophytes In Bacteria

    1023 Words  | 5 Pages

    INTRODUCTION An ‘endophyte’ is often a bacteria or fungus that colonizes the internal tissue of the plant showing no external symptom of disease or harmful effect on the host (Holliday, 1989; Schulz & Boyle, 2006). In practical terms, an endophytic bacterium is that, which can be isolated from surface-sterilized plant tissue (Perotti, 1926; Henning & Villforth, 1940). The early literature on bacterial endophytes was dominated by studies on plants of agricultural importance such as rice (Sun et al

  • Microorganisms In Bacteria

    MICROBIOLOGY IN FOOD INDUSTRY The tiniest life forms are bacteria, yeasts, molds, and viruses, termed “microorganisms” because of their size (micro meaning small and organism meaning living being). Bacteria Bacteria are the most important microorganisms to the food industry. Most are harmless, many are highly beneficial, some indicate the probable presence of filth, disease organisms, spoilage and a few cause disease. There are thousands of species of bacteria, but all are single-celled and fall into three

  • Bacteria And Archaea Similarities

    992 Words  | 4 Pages

    The living organisms are classified into different groups by means of their differences and similarities. Two of the major/ most important groups are the prokaryotes (Bacteria and Archaea) and eukaryotes (from plants, animals till malaria parasites and fungi). The difference between them is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, whereas the prokaryotic cells don’t. There is also a difference in their cellular structure due to the lack of chloroplast, cell wall

  • Stress Factors In Bacteria

    907 Words  | 4 Pages

    1. Introduction Bacteria have evolved several different mechanisms to enable them adapt successfully to their environment. All organisms have intrinsic genetic determinants that are expressed when challenged with different stress factors. Examples of such environmental stressors include antibiotics, chemicals, ionizing radiation, high salinity, extreme hydrostatic pressure, extreme temperatures and heavy metal stress, among others. When faced with single or multiple challenges, a series of transcriptional

  • Microbial Taxonomy In Bacteria

    880 Words  | 4 Pages

    Bacteria account for a major proportion of Earth’s biological diversity. They play essential roles in quite diverse environments and there has been an increasing interest in bacterial biodiversity. Microbial taxonomy deals with the classification (the orderly arrangement of organisms into taxonomic groups on the basis of similarity), identification and nomenclature (naming of taxa) of microorganisms (Coenye et al., 2005; Gevers et al., 2005; Mora & Amann, 2001; Vandamme et al., 1996). The terms Taxonomy

    Contamination with pathogenic bacteria from the human/animal reservoir can occur when the landing place is unhygienic or when the fish are washed with contaminated water. Upon the processing of fish, its exposure to water is a critical part as pathogens may be present in the water used which can cause contamination and spoilage (Shoolongela & Schneider, 2012). Contamination of food can occur because of problems in food production, preparation, storage or cooking. The aquatic environment and soft

    Oral bacteria are equally distributed worldwide; most of the same types of bacteria are present throughout the world. More specifically, they are independent of local differences. This happens because the teeth and the mouth cavity can easily support the formation of the biofilm due to their optimum conditions and their non-shedding effects. Furthermore, they have the ability to be transferred among the hosts by a direct contact of the mouth cavities and the exchange of saliva. 1.2. Bacteria and
