    EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x ). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x ). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2 .

Leuconostoc - Heterofermentative cocci, oval or spherical, occur in pairs or chains. 2. Pediococcus - Homofermentative cocci, often found in tetrads. 3. Lactobacillus - Homofermentative or heterofermentative rods, found singly or in chains. These organisms are gram positive, catalase negative, nonsporing cocci, coccobacilli or rods. They are microaerophilic that means they grow well under conditions of low oxygen content. Since they can grow under low oxygen conditions, they can grow throughout the wine (as opposed to on the surface of the wine) even though the container is kept full. The bacteria can metabolize sugars, acids and other constituents in wine and produce several compounds. Some of these are undesirable and constitute spoilage.
