  1. AceticOf, relation to, or producing vinegar, (acetic acid).
  2. Acetic acid The acid most commonly associated with vinegar C2H4O2 is the most commercially important organic acid and is used to manufacture a wide range of chemical products, such as plastics and insecticides. It is produced naturally by Acetobacter, but except for making vinegar, is usually made through synthetic processes.
  3. Acetobacter Acetobacter is a genus of rod-shaped, flagellated or non-motile Gram-negative bacteria that oxidize ethanol to acetic acid. These bacteria are commonly found on fruits and vegetables, and although they are used commercially to produce vinegar (especially Acetobacter aceti), they're considered pests by brewers and vintners.
  4. Acidic Sour; having a pH of less than 7.
  5. Acidosis A pathologic condition resulting from accumulation of acid or loss of base in the body, and characterized by increase in hydrogen ion concentration (decrease in pH.)
  6. Aerobic A process requiring oxygen or free air; conditions in which oxygen is present.
  7. Aflatoxin A fungal toxin which is a powerful liver carcinogen. It is produced by Aspergillus flavus and A. parasiticus, which grow easily on beans, grain, and peanuts which are inappropriately stored in warm, humid conditions. The presence of aflatoxins in contaminated food supplies is thought to contribute to the high levels of liver cancer in undeveloped and developing countries.

Mother of vinegar A film or membrane which is developed on the surface of fermented alcoholic liquids, such as vinegar, wine, etc., and acts as a means of conveying the oxygen of the air to the alcohol and other combustible principles of the liquid, thus leading to their oxidation. The film is composed of a mass of rapidly developing microörganisms of the genus Mycoderma, and in the mother of vinegar the microörganisms (Mycoderma aceti) composing the film are the active agents in the conversion of the alcohol into vinegar. When thickened by growth, the film may settle to the bottom of the fluid. See Acetous fermentation, under Fermentation.
  163. Vitamin B
  164. Vitamin B1 (thiamin) A water-soluble vitamin the body needs to make enzymes to break down carbohydrates. It is found in foods such as beans, green vegetables, egg yolk, liver, corn, and brown rice.
  165. Vitamin B12 (cobalamine) This ring-shaped, cobalt-containing vitamin is a crucial part of the entry of amino acids and fatty acids into the Krebs cycle. It is the only biomolecule known to have a carbon-metal bond.
  166. Vitamin B2 (riboflavin, lactoflavin) A water-soluble vitamin that serves as a hydrogen carrier in coenzymes involved in oxidation-reduction metabolic processes.
  167. Vitamin B3 (pantothenic acid) A vitamin found in all human cells which is a constituent of coenzyme A; it is a vital nutrient for some animal species, but humans don't seem to show any ill effects from a dietary deficiency of this vitamin.
  168. Vitamin B6 (pyridoxine, pyridoxal phosphate) Any of the various derivatives of pyroxidine; this water-soluble vitamin is a critical coenzyme in the metabolism of amino acids. It is found in most foods such as meats, liver, vegetables, whole-grain cereals and egg yolks.
  169. Vitamin B7 (niacin, nicotinic acid) This vitamin is necessary for the synthesis of various enzymes and acts to reduce blood cholesterol. A deficiency in this vitamin causes pellagra, which is characterized by dermatitis, diarrhea, and inflammation of the mucous membranes.
  170. Yeast Any of many small, single-celled fungi in the phylum Ascomycota that reproduce by budding; the yeasts used to produce alcohol through fermentation or to leaven bread are all in the genus Saccharomyces.
  171. Saccharomyces cerevisiae (baker's yeast, brewer's yeast, budding yeast) A species of yeast which is an important model organism for biological study, particularly for genetics and molecular biology. The entire genome of this species has been base sequenced and it is used to do research on the basic cellular mechanics of replication, recombination, cell division and metabolism. S. cerevisiae is also economically important in the food industry, where it is used to ferment grain sugars to make beer and as baker's yeast for baking bread or making other food which requires rising by gas bubbles of carbon dioxide. It is also sometimes taken as a vitamin supplement for protein, the B vitamins, and folic acid.
  172. Schizosaccharomyces pombe (fission yeast). S. pombe is a species of yeast, also called fission yeast, which is used as a model organism for biological and medical study. They are useful because most of the time they are haploid so that both recessive and dominant mutations in the genome will result in a mutant phenotype (since each individual yeast cell has only one copy of each gene, unlike in diploid organisms where a normal copy of a gene can make up for recessive mutations, resulting in mutant phenotypes only for dominant mutations).
  173. Killer yeast A yeast that secretes a toxin that can kill other yeasts.
  174. Zinc A bluish white metallic chemical element that tarnishes only slightly in moist air at ordinary temperatures and is used especially as a protective coating for iron.
  175. Zooglea.[zoogloea] A jelly like mass of bacterial cells produced by species such as Zooglea ramigera. These masses are often used in the treatment of raw sewage.
  176. SCOBY Acronym for Symbiotic Colony Of Bacteria and Yeast. (the pellicle, the "mother" colony, the "baby" colony.)
