The Effects Of Microorganisms And Its Effects On The...

Introduction: Microorganisms have been used by human beings to their benefit for centuries. Ancient biotechnology utilized yeast to make bread and wine – perhaps well before they even knew that tiny microbes were causing bread to rise, or grapes to ferment! In the modern day, the use of microbes has extended so far as to actually help us reverse the damages we cause to the environment. One such environmental application of microorganisms is Bioremediation – the use of either indigenous or Hydrocarbonoclastic bacteria (HCBs) to rapidly digest hydrocarbons from oil spills. According to a recent study by The International Tanker Owners Pollution Federation Limited, between 2010 and 2012 there were 21 tanker spills, 5 of which were above 700 tons (2012). The use of often naturally occurring bacteria to digest these oil spills is now being heavily studied and implemented as a means to clean up these disastrous oil spills. Biostimulation (the addition of inorganic nutrients that would normally be limiting) has been studied as a potential measure to encourage indigenous microbes to increase their rate of hydrocarbon digestion in order to expedite the process of oil spill clean-up. Bioaugmentation, the process of introducing HCBs to a native community to increase efficacy of bioremediation, has also been studied in addition to the effect of the addition of surfactants in both cases (McKew et al., 2007). Because oil-spills tend to contain everyShow MoreRelatedMicrobial Pathogens And Its Effects On Human Health Essay912 Words   |  4 PagesINTRODUCTION Food may be contaminated with a range of microorganisms during harvesting, processing, handling operations and indirectly by way of contaminated water. Eventually, even during distribution and storage only a small quantity of these will develop and cause serious deteriorations known as food spoilage. Contamination of food with pathogens leads to foodborne diseases. Foodborne disease is any illness that results from the spoilage of food contaminated by pathogenic bacteria, viruses,Read MoreBeneficial Effects of Probiotics Essay1408 Words   |  6 Pages INTRODUCTION Probiotics are ingestable microorganisms which gives the consumer a beneficial effect. First coined by the late eli Metchnikoff probiotics are described to be microorganisms which are ingested in small amount to increase the diversity of both flora and fauna inside the human body this reaction in turn affects the adaptation abilities for the human body to react to different surroundings, digest different things, or just improve the antibody or the mechanism that already exists in theRead MoreSymptoms And Treatment Of Infectious Diseases1100 Words   |  5 Pagesinfectious diseases start at the surface of the host. The only exception is certain intrauterine transmitted infections. The initial barrier is the skin, respiratory tract, or the gastrointestinal tract. The specific surface involved relates to how the microorganism reaches the host. Most infectious diseases begin with exposure to the infectious agent. Following that in an incubation period and then the manifestations of the disease. An inflammatory response usually brings patients to a doctor because ofRead MoreGlobal Warming : A Potential Solution1330 Words   |  6 Pagessocieties are now tormented by several pollution problems that were largely unknown prior to WWII. Prominent among these problems is environmental pollution of xenobiotic synthetic chemicals that fail to be recycled by microorganism and may be biomagnified with destructive effects. Also, deforestation, land conversion, overhunting and the burning of fossil fuels are other human’s activities that impact negatively our ecosystem. Contributing to global warming, the devastation of the coral reefs, wildlifeRead MoreTypes Of Bacteria And Its Effects On The Environment890 Words   |  4 PagesMicrobes are ubiquitous in the biosphere, and their existence invariably influences the environmen t that they are growing in. The environment in this case can be air, water, or soils that cover the planet. Depending on the types of bacteria, their effects on the environment could be harmful, unapparent, or beneficial with regard to human observation. Using microorganism to study environment may provide a clearer picture about how complicated ecosystem is operating. Since microbes are very small,Read MoreCadmium And Its Effects On The Environment Essay1345 Words   |  6 Pagesis present on earth crust as heavy metal and its exposure in environment is very big challenge to environmentalist because cadmium is non-degradable in nature. In environment cadmium transfers from one trophic level to another and finally accumulated in human with toxic effects. There is an emergent need to remove the cadmium from environment. Microbes are very helpful in this area to remediate the cadmium from environment. Microorganisms used biotransformation and adsorption mechanisms for regulationRead MoreMrsa Case Study1342 Words   |  6 Pages DISCUSSION In the present study a total of 270 personnel screened for microorganisms and MRSA carriage. From these personnel 91(33.7%) Dentists, 89(32.9%) Nursing staff and 90(33.3%) were patients. Among 270 DHCPs screened, thirty were positive for MRSA either in nose or hands giving a carriage rate of 11.1%. The proportion of personnel with nasal carriage of MRSA was higher (14.7%) than hand carriage (9.3%) this result agreed with that of Kalyani et al. (2012) where personnel carriage of nasalRead MoreWater Pollution And Its Effects On Aquatic Life1526 Words   |  7 PagesWater Pollution and its Effects on Aquatic Life Charles Darwin, the father of evolutionary biology, states in his theory of evolution that only organisms better fit to survive in their environment will survive. Based on his theory and research, it can be concluded that challenges to the environment directly affect the organisms. Research shows that in particular water pollution; hospital wastewater and sewage wastewater, is shown to cause antibiotic-resistant microorganisms, excess nutrients suchRead MoreThe Health Of Humans And Companion Animals1120 Words   |  5 Pagespractice. Probiotics are living organisms that naturally inhabit the gastrointestinal tract of both humans and companion animals. These microorganisms survive the highly acidic environment of the monogastric gastrointestinal tract and can be found living in the feces. Improvement of physical symptoms as well as the levels of microorganisms within the feces measures the effects of probiotics (Bybee et al., 2011: Scharek-Tedin et al., 2013: Lee et al., 2012). Resea rchers utilizing probiotics have addressedRead MoreConsiderations of Food Safety1128 Words   |  4 PagesFood safety is one of the primary concerns in our industry, especially to those who process food in large amounts. Therefore, proper sanitation must be provided in order to destroy microorganisms that could possibly spoil and contaminate food products. Sanitizers are substances used to reduce and inhibit most microorganisms present in surfaces of equipment and utensils. They are usually in the form of liquid mixture applied directly on the surface of equipment or any material that may come in contact
