How to Deal with Drug Resistant Bacteria - Anti-Anti-Bacterial Bacteria Although there are many different types of bacteria that are not only beneficial towards human life, but also vital. All bacteria, like humans and most other living organisms that exist, share the common goal, of wanting to exist, and to carry on existing, via reproduction. Whether this reproduction takes place through the form of live birth, by means of hatching from an egg, cell division, or any of the countless number of methods of continuing a species that have been created by the corresponding number organisms that have been, are still to come, and are currently in the cycle of existence, it is still part of the not entirely different goal, of continuing to...   [tags: harmful bacteria, organisms, reproduction] 755 words

Phylogenetic Analysis of Thermophilic Bacteria - We report the community of thermophilic bacteria cultivated from Tanjung Sakti Hot Spring in South Sumatera Indonesia that has temperature 80 – 91 0C and pH 7 – 8. Based on phylogenetic analysis, the 16 sequences of 16S rRNA gene fragments obtained from the community clustered within four distinct genera as Anoxybacillus, Geobacillus, Brevibacillus, and Bacillus. Two sequences that have 96% similarity with data sequences in GenBank, are potentially as novel species/sub species. Hot spring is a unique area that characterized by high temperature and has a great diversity of natural environments....   [tags: Bacteria, Tanjung Sakti Hot Spring, South Sumatera]

Antibiotic Resistant Bacteria - Bacteria refer to a large domain of prokaryotic microorganisms (microscopic organisms that lack a membrane bound nucleus). They are very abundant in nature. For example, according to Christian Nordqvist (2009), a gram of soil can contain up to forty million bacterial cells. Bacterial microorganisms can be found almost anywhere and can adjust extremely well to surrounding conditions. Not all bacteria are harmful and even play an important role in the recycling of nutrients. By recycling nutrients bacteria become a valuable resource for the human body....   [tags: bacteria, probiotics, pathogenic] 668 words

Bacteria and Viruses - Bacteria are unicellular organisms called prokaryotes. Viruses are pieces of biomolecules that cannot reproduce independently. Both groups may be pathogens, or may be beneficial- sometimes, the same species or variety may be both, depending on circumstances (Starr, C., and Taggart, R., 2004.) Throughout history, pathogens and more helpful species have played vital roles in the development of humanity as a species and of the human social arrangement.

Bacteria - Describe the structure and life processes of bacteria. Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule....   [tags: essays research papers] 611 words

Bacteria - Bacteria Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic, measuring 1 micron in length. However, colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more than 3 billion years ago. Archaebacteria live in environments where, because of the high temperature, no other life can grow....   [tags: Science Chemistry Biology Experiment Essays]

How Does Music Affect Bacteria Growth? - My experiment is going to be how music affects bacteria growth. However because bacteria is “deaf” and actually cannot hear music it can only hear the vibrations emitted from the music. I am going to test how different genera vibrations from rock, classical, pop, and techno music affect the growth. However, before we see why music affects bacteria you would need to know how bacteria grows normally. For bacteria to grow you need four components: food, temperature, moisture, ph. level, oxygen and time....   [tags: vibration, temperature, oxygen, ultrasound]

Bacteria, fungi, protists and other microorganisms in a non-polluted environment are constantly breaking down organic matter, and when the soil is polluted, some of the organisms may die, but others will still be able to break down the pollutants. Bioremediation provides organisms that can consume the pollutants with fertilizer, oxygen, and other conditions to encourage the rapid growth of these organisms....   [tags: envrionment problem, organisms]

Mutation of Bacteria from Virus Sensitivity to Virus Resistance - The usage of antifungal agent 5-fluorocytosine (5-FC) as a treatment of cryptococcal diseases has been ineffective due to the development of resistance during the treatment [1]. Block et al. conducted fluctuation analysis in order to characterise the nature of 5-FC resistance to see if the resistance was a result of interaction between yeast cells and 5-FC or due to spontaneous mutation. The procedure was carried out in accordance to the experiment performed by Luria and Delbruck [2]. Initially, the minimal concentration of the 5-FC and 5-fluorouracil (5-FU) that inhibited the growth of Cryptococcus neoformans or simply minimal inhibitory concentration (MIC) was determined....   [tags: antifungal agent, fluorocytosine, treatment]
