Additionally the development of recombinant DNA technology through the use of bacteria has led to the birth of modern genetic engineering and biotechnology. [ 9 ] Using microbes, protocols were developed to insert genes into bacterial plasmids , taking advantage of their fast reproduction, to make biofactories for the gene of interest.
Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Environmental biotechnology can simply be described as "the optimal use of nature, in the form of plants, animals, bacteria, fungi and algae, to produce renewable energy, food and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process". [3]
Bacteria can be used for the industrial production of amino acids. organic acids , vitamin , proteins , antibiotics and other commercially used metabolites which are produced by microorganisms. Corynebacterium glutamicum is one of the most important bacterial species with an annual production of more than two million tons of amino acids, mainly ...
Microbes are important in human culture and health in many ways, serving to ferment foods and treat sewage, and to produce fuel, enzymes, and other bioactive compounds. Microbes are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism .
Consequently, the need to identify human pathogens was a major impetus for the development of techniques to identify bacteria. [ 173 ] The Gram stain , developed in 1884 by Hans Christian Gram , characterises bacteria based on the structural characteristics of their cell walls.
The human gut microbiome consists mainly of four phyla: Firmicutes, Bacteroidetes, Actinobacteria, and Pseudomonadota. [10] Microorganism gut colonization is dynamic from birth to death, with stabilization at the first few years of life, to higher diversity in adults, to reduced diversity in the elderly. [ 10 ]
Scanning electron micrograph of Escherichia coli, a common human pathogen and research organism.. Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them.
