The lactic acid bacteria (LAB) are either rod-shaped ( bacilli ), or spherical ( cocci ), and are characterized by an increased tolerance to acidity (low pH range). This aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid ).
Rhodospirillales. Family: Acetobacteraceae. Genus: Acidiphilium. Type species. A. cryptum. Acidiphilium is a genus in the phylum Pseudomonadota ( Bacteria ). [1] As the name suggests, this comprises a nutritionally diverse genus of bacteria adapted to life in extremely acidic conditions, and often exhibiting FeIII (ferric iron) reduction.
Discovery and history. Synthesis. Mechanism of action. Symptoms of poisoning and treatments. References. Bongkrek acid (also known as bongkrekic acid [1]) is a respiratory toxin produced in fermented coconut or corn contaminated by the bacterium Burkholderia gladioli pathovar cocovenenans.
They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust.
Klebsiella oxytoca is a Gram-negative, rod-shaped bacterium that is closely related to K. pneumoniae, from which it is distinguished by being indole-positive; it also has slightly different growth characteristics in that it is able to grow on melezitose, but not 3-hydroxybutyrate.
CRISPR (/ˈkrɪspər/) (an acronym for clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea.[2] These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and ...
Omega−3 fatty acids, also called Omega−3 oils, ω−3 fatty acids, Ω-3 Fatty acids or n−3 fatty acids, [1] are polyunsaturated fatty acids (PUFAs) characterized by the presence of a double bond, three atoms away from the terminal methyl group in their chemical structure. [2] They are widely distributed in nature, being important ...
