The lactic acid bacteria (LAB) isolated from wine are located in two families and three genera (with several species and strains). The Lactobacillaceae, represented by the genus Lactobacillus, includes rod-shaped Gram-positive species and their respective strains (see Fig. 1-1), whereas the Streptococcaceae represented by the genera Pediococcus and Leuconostoc, includes Gram-positive coccoid- or coccobacilloid-shaped isolates (see Figs. 1-2 and 1-3). Both groups may grow as somewhat characteristic aggregations of cells. These may include chains of lenticular or sausage-shaped cells, in the case of Leuconostoc oenos, filamentous chains (Lactobacillus fructivorans), and tetrads that result from division in two planes (Pediococcus damnosus).
