Bacterial Colonies are groups of bacteria growing on a solid medium; Fungal Colonies are groups of fungi, often with visible structures, growing similarly.
Bacterial ribosomes are of 70S type and quite smaller than eukaryotic 80S types. They are made up of 2 subunits, the 50S, and 30S. Their main role is to synthesize bacterial proteins and enzymes. They are target sites for different antibiotics like erythromycin, macrolides, aminoglycosides, etc...
Probiotics are the “good” or “friendly” bacteria in the GI tract. They are markers for good digestive health. A healthy adult human should be host to 3-5 pounds of these microbes (at least 70 trillion — more bacterial cells in the host than actual DNA-containing cells). Probiotics a...
What are the underwater bacterial colonies called? What kingdoms are prokaryotic? Do marine bacteria create dissolved oxygen? What are the phytoplankton functional types? What dissolved gases are required by nearly all marine organisms? What is the study of microscopic organisms?
Define a bacterial colony. List four characteristics by which bacterial colonies may be distinguished. What are the differences between bacteria and archea? What process is best for the short-term storage of bacterial cultures? What is a plasmid and how is it passed between bacteria?
Bacterial colonies with an empty plasmid (i.e., plasmids without a DNA insert) turn blue. This occurs because of a process called alpha-complementation in which the lacZ gene in the cloning vector complements the lacZ deficient E.coli cells. The gene expression of lacZ is induced by IPTG an...
They are one of the earliest colonizers. They can be unicellular, filamentous or occur in colonies. The filament has mucin covering. There are no flagella for locomotion of bacteria. Their cells are larger than normal bacterial cells. Their cell wall is multi layered. It includes peptidoglycan ...
N-Z-AMINE A can be used to treat the physical and chemical properties and bacteria of casein hydrolyzate on glutinous rice sourdough. Effect of bacterial flora structure Add casein hydrolyzate to glutinous rice to prepare sourdough, explore the changes in the physical and chemical properties of glu...
Teeth Crowding –When a person’s teeth are crowded or overlapping, they are naturally harder to clean and more likely to trap food in tough-to-reach spaces. This also creates perfect hiding spots and breeding grounds for bacterial colonies to flourish and cause caries. ...
What is the importance of generating isolated bacterial colonies? Bacteria: Bacteria are single-celled and microscopic organisms that cannot be seen by the naked eye. A group of bacteria obtained from the same mother cell forms a bacterial colony. A bacteria colony constitutes genetically identical...
