Bacteria They are formed by a single rudimentary cell. They have no nucleus or plastids, but chromatin. Some have assimilators pigments. They are on earth, water, and air, and can generally move. They may be causing disease and therefore are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in digestive processes or synthesis of vitamins. By the way, they are called coconuts when circular; bacilli if they have the form of rods;…

Civil Rights Then & Now Reflection Essay Many will ask what civil rights is, in other words Civils Rights : is the right of citizens to political and social freedom and equality. Civil Rights come from the federal legislation or the federal court decisions. Certain states usually pass their own civil rights laws. If you can remember parts of Martin Luther King Jr. speech you would be able to recall that he tend to speak upon economic freedom and poverty. Many will come to think that…

Cream may have the potential for use as a probiotic carrier because it provides an excellent environment for probiotic bacteria, with the added advantage of having nutritional value.Fatty Acids composition in fermented synbiotic cream, containing one of the two probiotic bacteria ( Lactobacillus acidophilus, Lactobacillus casei ) and inulin (0,1.5, 3%) was evaluated during 30 days for the the15-day interval at 4±1 °C. All chemical characterization were affected by the probiotic bacteria strain…

Violet red bile agar is a selective medium used to identify lactose-fermenting coliforms. This medium is typically used to test dairy products and water. The medium contains lactose which acts as a carbohydrate source, bile salts and crystal violet that act as an inhibitory agent towards gram-positive microorganisms and neutral red is added to serve as a pH indicator, microorganisms lower the pH which results in the colonies turning red. Some of the organisms that grow on this medium are:…

CLOSTRIDIUM TETANI Introduction Clostridium tetani is a microorganism that has effected the lives of many people. This bacteria is the cause of the disease many people have come to know as Tetanus. It infects its victims by releasing a toxin in the human body that causes an infection in the nervous system (Hassel, 2013). The first experimentations with Tetanus began in the 1800’s when scientists began infecting animals with samples from infected humans. In 1889, one scientist by the name…

Staphylococci are catalase positive, while Streptococci negative. To future identify species of Streptococci, growth on blood agar plate will be necessary to recognize level of haemolysis. S. pneumonia is α-haemolysis (Allegrucci and Sauer, 2006), which will appear as dark greenish discoloration under the colonies…

ferric chloride was added to phenylalanine deaminase tube, it turned into army green color( positive result) which indicated that unknown microorganism contains phenylalanine deaminase enzyme. On the other hand, no color change in the slant indicates negative result for this test. The choices between two…………………. was narrowed down By performing this test. The positive result for phenylalanine deaminase indicated the unknown microorganism #404 is P.vulgaris. To check motility of an unknown…

Jaqueline Moreira Biology 23 March 8, 2016 Pseudomonas aeruginosa Introduction P. aeruginosa belongs to the family called Pseudomonadaceau ( Willey, J., Prescott Microbiology, 2014, p.527). P. aeruginosa is a gram negative bacterium. The shape of this particular bacterium is straight or slightly curved rods, but not helical. The size of this bacterium is about 0.5-1.0 micrometers wide and 1.5-5.0 micrometers long. The arrangement is single, but as is starts to age it forms cysts. P.…

Anthrax is a highly infectious disease that normally affects herbivores (livestock) and unfortunately may also spread to humans through inhalation, ingestion or any sort of skin contact of the bacterium, Bacillus anthracis. Bacillus anthracis (B. anthracis) is a gram positive spore forming bacterium that invades the human body and leads to various symptoms of Anthrax, depending on how virulent it has become. These symptoms include; swollen neck glands, bloody diarrhoea, vomiting blood, extreme…

supposed to determine either the bacteria is classified as gram-positive or gram-negative (Sadava, 2011). We dropped KOH with our bacteria and mixed it. After about a minute, we should have been able to tell if a string has formed or not. We have didn’t have a string form, so we had gram-positive bacteria and a negative string test result. We then did other tests because the string test has a high possibility for false negatives and results can be inconclusive. We swabbed out bacteria on…
