Thus, the bacteria can use virtually any organic structure.  Bacteria as pathogens Although they are the smallest cells in biocoenosis, their role is even more important. Some bacteria are even able to assimilate (e.g. cyanobacteria or "blue-green algae"). Some of the bacteria decays or rots other organisms to feed themselves.
Beside, they have no impacts on viruses as well as they can not cure viral diseases such as cold and flu. Antibiotics are important and effective. They either restrict and limit the bacteria reproduction and multiplication or kill them directly. They have an advantage of being able to differentiate between the bacterial cells and host’s cells. On the other hand, they also have a disadvantage for patients who suffer from frequent infections.
ODUCTION BY: SIMANG CHAMPRAMARY Microbiota is the community of organism that dwells at different sites in the human body. There are billions of different organisms but the only known communities which could be identified are Firmicutes, Bacteroidetes, Actinobacteria, Fusobacteria, ProteobacteriaandVerrucomicrobia. They are important to us because: • They are responsible in providing us with necessary vitamins • Digesting oligosaccharides • Training our immune system and inhibiting pathogenic organisms The presence of various community of microbes are shaped by: • Mode of delivery in birth: children born in normal delivery mode will have different community of microbes compared to children born with C-section. • Food: Different types of food
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
Nitrate serves as a source of nitrogen for many bacteria. They can also act as a final electron acceptor. Many bacteria can be differentiated and are identified by their capacity to reduce nitrates to nitrites. Most of the bacteria belonging to the family Enterobacteriaceae reduce nitrates . OF test is used to differentiate those organisms that utilize carbohydrates aerobically (Oxidation) such as P. aeruginosa, from those that utilize carbohydrates anaerobically (Fermentation) such as members of the Enterobacteriaaceae.
However, the cons are they can cause diseases, pathogenic, and etc. Without bacteria there will be no life in the world, as it is responsible for beginning everything. The next domain and kingdom to exist was Archaea. They are organisms that can survive in extreme habitats as in volcanoes, deserts, and even Antarctica. They are heat loving bacteria which are called Extreme Thermophiles, and
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
Aerin Nortier Grade 11.2 Biology research project Introduction Bacteria are everywhere some harmful and others not, without bacteria the world would be nothing. In this research paper I will be discussing bacteria, anti-bacterial agents, pros and cons of bacteria and my conductive experiment on the growth and the killing of bacteria. Bacteria are single cellular organisms that most commonly reproduce through means of binary fission. They were first discovered by Anton Leeuwenhoek in 1676 and are classified as Monera in the five kingdom classification system. Anti-bacterial agents kill or inhibit bacterial growth.
Protozoan infections are a common matter in tropical countries and have severe impact on public health issues (Department of Dermatology at Federal University of the state of Rio de Janeiro). The ecological role of protozoa is very important; they play an important role in the food chain. In aquatic ecosystems, protozoa act as dominant consumer of bacteria [Fenchel 1984, Sieburth 1984, Porter et al. 1985] whereas ciliated protozoa are considered as bacteriovore only in sediments, or in particular material [Caron et al. 1982, Sieburth 1984, Silver et al.
Microbes and its properties In industrial, the used of microorganisms must be suitable and does not give the harm effects towards the animal, human and plants organisms. The microorganisms are should be able to protect itself from dangerous. The preferred organism to used in industries is must be in a large size of cells. It is due to the larger cells size, the faster the cells to be settle from a culture of the materials process. The examples of favourable microorganismto used in idustrial are like yeast, filamentous bacteria and yeast.
