: cause diseases in humans and crops. Bacteria play an important role in the nitrogen cycle. Nitrogen fixing bacteria convert nitrogen into nitrates and denitrifying bacteria convert nitrates into nitrogen. Bacteria can cause food poisoning. If food is contaminated or not stored properly bacteria will grow and will make you very sick Some bacteria are used to combat pollution known as Bioremediation.
 There are microbes, which are beneficial to the human in production of food or the medical and pharmaceutical field. Microbes are biologically wired to carry out certain functions. Some of these functions are – being able to pass on the entire genetic information to the next generation, produce viable offspring to prevent extinction, and lastly being able to adapt and change to environmental changes so that any dire change would not be able to wipe off the entire colony. However there are also microbes that cause harm to the human body. These harmful microbes are termed as pathogens.
Then finishing the essay will be the conclusion. Bacteria The bacteria are one of the six municipalities of living. Bacteria are single-celled microbes, or small organisms. Bacteria are prokaryotic, which means that they do not have a nuclear membrane around the genetic material. With the exception of Ribosomes, bacteria do not have cell bodies.
Since there are pathogenic and non pathogenic microbes, we should be more carefully in handling it. Some of the pathogenic microbes can give us disease where it can lead to fatal. But, from the non pathogenic microbes itself, it can helps us in various industry. Sometimes, from the non pathogenic microbes it can helps in finding the cure for the pathogenic microbes. Microbes are important for human and also all living things as it play the role of cycling back every ‘ waste’.
One example includes the industry of food production, where microbes hold a immense responsibility both on small scale, inside homes and on big scale too. For example, bacteria (lactic acid) can be used to make fermented milk products such as yogurt, sour cream, cheese etc. Also, Wine and beer can be made by using yeast, and vinegar by bacterial acetic acid fermentation. The other areas of benefits of the microbes include the medical field as many microbes are used as a source of vaccines and antibiotics, also they can be used to fight against other bad microbes. Microbes are also used in wastewater treatment and in agriculture too.
Dr Tracy Ainsworth stated “it is very likely that these microorganisms play a vital role in the capacity of coral to recovering from bouts of bleaching caused by rising temperatures.” Corals rely on these good bacteria’s crucially although we don’t yet understand these microbe’s ell enough to know how they influence coral survival, which is vital in maintaining the food web of the Great Barrier Reef. These good bacteria as well as other decomposers break down dead organics material and turn nutrients to the sediment. This energy is then obtained by the producers and the cycle begins
In those researches they did surveys, in places like Mexico and Washington’s coast and under the oceans, and saw that due to bacteria’s adaptably their biomass may exceed that of life in oceans. Bacteria also prospers by creating a symbiotic relationship with other plans, like the plants which enable them to convert atmospheric nitrogen to ammonia. Symbiotic bacteria also play a significant role in producing vitamins and breaking down food that contains
These days, there are many causes of health problems, but one of the major ones are microorganisms. Microorganism are all around us, but not all of them are harmful. Disease-causing microorganisms are called pathogens. Pathogens include, bacteria, viruses, fungi etc. most pathogens live off of other living organisms.
While this infection of bacteria doesn’t cause harms in most cases, still it can cause diseases in few people. For their survival in your stomach, the bacteria change the surrounding around them by lowering the acidity in order to survive. Their spiral shape allows them to penetrate your stomach protective lining called mucus; where your body’s immune cells cannot reach. Thus, bacteria can easily interfere with your body’s immune response to make sure they don’t get destroyed.
Bacteria thrive everywhere even in food samples. Some of these bacteria are helpful and useful while others are detrimental and can cause a wide variety of life threatening diseases (Pommerville, 2011). Microorganisms are plentiful and omnipresent in nature and their role as causative agents of food borne illnesses was known way back in the 19th century (Mbah et al., 2012). It was revealed by the end of the 19th century that microorganisms were accountable for a range of food borne diseases (Mbah et al., 2012). Gram- negative bacteria are a group of bacteria that do not retain the crystal violet stain used in Gram staining method of bacterial differentiation (Wikipedia, n.d.).
