Ribosomes: The protein-making machinery has 70S ribosome which is of two sub-units as 50S and 30S. Do you have PowerPoint slides to share? Hence irrational use of antibiotics. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. In transformation, one bacteria release naked DNA strand into the surroundings. In this study, we investigated the influence of audible sound waves stimulation on bacterial cell E. coli growth, energy metabolism level, synthesis of protein and activities of anti-oxidant enzymes. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. 9. They perform, nick and joint function in the DNA chains. No nucleus: Unlike another eukaryotic cell, the bacterial cell is the only cell which lacks a prominent … Cell shape, nature of multicell aggregates, motility, formation of spores, and reaction to the Gram stain are important.

Bacteria synthesize macromolecules required for multiplication. They are present at very cold (minus degree) temperature regions and also very high-temperature regions. Bacteria are more tolerant to osmotic variation than most other cells due to the mechanical strength of their cell wall. They are all artistically enhanced with visually stunning color, shadow and lighting effects. The length of lag phase depends on the conditions in the original culture and the medium into which they are Describe the different types of bacteria 3.

The other bacteria take it up and incorporate into their genome. 15. Find an answer to your question Morphological and physiological characteristics of bacteria 1. Please check. These bacterial structures have a specific shape like a stick (bacilli), spherical (cocci), coma (cholera bact. Spore formation: When the environmental conditions around are harsh, the bacteria convert to a hard spore form. Microbiology, the scientific study of microorganisms, a diverse group of generally minute simple life-forms, including bacteria, algae, and viruses. We have updated respiration method in the bacteria there. Bacteria are typically single-celled organisms called prokaryotes that may serve as digestive aids, cause disease or aid in decomposition. Bacteria do not have mitochondria like a typical animal and plant cells. - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. Some of them synthesize their food like plants by use of sunlight. 8. These characters make them immortal, omnipresent and also very versatile. Osmotic pressure • Bacteria are about 80-90% water; they require moisture to grow • Bacteria in hypertonic media causes water loss by osmosis and cell wall separates from cell membrane called as plasmolysis • Bacteria in hypotonic media causes water to enter inside the cell called as osmotic lysis The four groups resemble the genera Bacteroides, Sphaerophorus, Veillonella and Peptostreptococcus as described in Bergey's Manual (Breed, Murray & Smith, 1957). They produce over two-thirds of the clinically useful Some phenotypic characteristics of actinobacteria are of such primary importance to a genus or species description. Log in. Even they aquire a tolerance to harsh chemical and other stuff which destroy them. CHARACTERISTICS OF BACTERIA Lab #9 I. Physiological Characteristics of 2. These bacteria stain purple after Gram staining. Cosmopolitan distribution: Bacteria are the only organisms which show cosmopolitan distribution. Therefore, study of bacterial diversity is an important step to understand their role in aquatic ecosystems. Cultural and 10. 6. But bacteria have different modes of food procurement. The Most Common Morphologies are: Ex: rhizobium in roots, E-coli in the intestine. You question has been answered in the point 6.

Bio-cabinets 6. a. Asexual reproduction: The bacteria cell undergoes to produce two bacteria by Binary fission and also by endospores. On the prokaryotic side, there are diverse forms of bacteria and a group generally termed blue-green algae. But bacteria especially the gram-negative ones have an extra membrane, i.e., an outer membrane called periplasm which lies bellow cell wall but above the cell membrane. The wall is made of different substances like glycoproteins, lipopolysaccharides and lipoproteins.

Few of them are parasites which live on alive plants and animals. Cell membrane: This is present immediately below the cell wall. Microbial metabolism is the means by which a microbe obtains the energy and nutrients it needs to live and reproduce. Many bacteria are saprophytes which means, they live on dead and decaying matter. - Structure and Characteristics of Bacteria CELL WALLS OF GRAM-POSITIVE AND GRAM-NEGATIVE BACTERIA The structure, chemical composition, and thickness of the cell wall ... - Characteristics of microbes Major groups of microorganisms Viruses Not cells; contain either RNA or DNA in envelope; can only multiply in living cells.

In the higher cells, aerobic respiration occurs due to the glycolysis and oxidative phosphorylation pathway in the mitochondria. 4. aerobic and anaerobic bacteria, gas forming bacteria, etc.). Also referred to as blue-green algae and blue-green bacteria, cyanobacteriais a bacteria phylum that obtain their energy through a process known as photosynthesis. b) Sexual reproduction: It is also by two distinct methods like transformation, conjugation, and transduction. The specific metabolic properties of a microbe are the major factors in determining that microbe's ecological niche, and often allow for that … Decomposition activity is related to the type and dominance of bacteria in the communities. They are long filamentous organs originating from the cell membrane. Ask your question. 6. good website gives a lot of ideas for my science project, Good website and gives a lot of ideas too. The external and internal characteristics of bacteria are a bit different from the rest of the organisms on the earth. Thanks for stopping by. ADVERTISEMENTS: Some of the important characteristic features of Cyanobacteria are as follows! THis has become so severe that the World Health Organization warns of the rampant prevalence of resistant bacteria which can be incurable by currently available drugs. The biochemical characteristics of a bacterium provide many traits that are useful for classification and identification. They can live in an acidic environment (Helicobacter pyroli) and even alkaline environment (iron bacteria). 1. While others are symbiotic. Gram positive bacteria have cell walls composed mostly of a substance unique to bacteria known as peptidoglycan, or murein. 7. Respiration: Bacteria do not have mitochondria like a typical animal and plant cells. In general, the skin is cool, acidic and desiccated, but distinct habitats are determined by skin thickness, folds and the density of hair follicles and glands 8 . Lactic acid bacteria are widely used in the dairy industry, and acetic acid bacteria in vinegar production. However, they derive energy by aerobic respiration. In Humans and other mammals, instead of DNA gyrase, there is DNA topoisomerase-II for a similar function.
