Bacteria are also used for the bioremediation of industrial toxic wastes. [238] In the chemical industry, bacteria are most important in the production of enantiomerically pure chemicals for use as pharmaceuticals or agrichemicals. [239] Bacteria can also be used in place of pesticides in biological pest control.
Of specific interest are the red regions of the middle column, indicative of purple non-sulfur bacteria (e.g. Rhodospirillaceae). Also, in column three, the red growth along the side of the column: a purple sulfur bacterium, Chromatium. The Winogradsky column is a simple device for culturing a large diversity of microorganisms.
Bacteria function and reproduce as individual cells, but they can often aggregate in multicellular colonies. [54] Some species such as myxobacteria can aggregate into complex swarming structures, operating as multicellular groups as part of their life cycle , [ 55 ] or form clusters in bacterial colonies such as E.coli .
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
Spiral bacteria are another major bacterial cell morphology. [2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [33] Bacteria are known to evolve specific traits to survive in their ideal environment. [34]

School children sharing sports and other equipment; College students living in dormitories [6] People staying or working in a health-care facility for an extended period of time [5] [6] People who spend time in coastal waters where MRSA is present, such as some beaches in Florida and the West Coast of the United States [14] [15]
As mentioned, S. agalactiae is a Gram-positive coccus with a tendency to form chains, beta-haemolytic, catalase-negative, and facultative anaerobe (anaerobic organism).GBS grows readily on blood agar plates as microbial colonies surrounded by a narrow zone of β-haemolysis.
