E. coli belongs to a group of bacteria informally known as coliforms that are found in the gastrointestinal tract of warm-blooded animals. [ 49] E. coli normally colonizes an infant's gastrointestinal tract within 40 hours of birth, arriving with food or water or from the individuals handling the child.
Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae . T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle .
Bacteriophage. Anatomy and infection cycle of bacteriophage T4. A bacteriophage ( / bækˈtɪərioʊfeɪdʒ / ), also known informally as a phage ( / ˈfeɪdʒ / ), is a virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν ( phagein ), meaning "to devour".
As with other members of the genus Bacillus, it can form an endospore, to survive extreme environmental conditions of temperature and desiccation. [12] B. subtilis is a facultative anaerobe [6] [13] and had been considered as an obligate aerobe until 1998. B. subtilis is heavily flagellated, which gives it the ability to move quickly in liquids.
Plant morphology. Phytomorphology is the study of the physical form and external structure of plants. [ 1] This is usually considered distinct from plant anatomy, [ 1] which is the study of the internal structure of plants, especially at the microscopic level. [ 2] Plant morphology is useful in the visual identification of plants.
Plant taxonomy. Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two.
Iodine is an essential trace element in biological systems. It has the distinction of being the heaviest element commonly needed by living organisms as well as the second-heaviest known to be used by any form of life (only tungsten, a component of a few bacterial enzymes, has a higher atomic number and atomic weight ).
Rhizopus oryzae grows quickly in optimal temperatures, at 1.6 mm per hour (nearly 0.5 μm per second - enough to be able to directly visualize hyphal elongation in real-time under the microscope). [1] R. oryzae can grow in temperature of 7 °C to 44 °C and the optimum growth temperature is 37 °C.
