Resumo: 	After the enumeration of hétérotrophie bacteria from mediterranean and atlantic lagoons water and sediment by means of cultural methods, the qualitative study of each bacteria is carried on with the help of the API 20 B standardized microbiological method. The distinctive characteristics of bacteria of each communities are coded so that to build matrix of binary data. The grouping of bacteria is realized by means of both linnean systematic and numerical taxonomy. The communities structure they constitute found expres­sion in a systematic dominance index (D2), a Shannon taxonomic regularity index (J) and a "functionnal" regularity index (E). To have a better description and interpretation of the main ecological features of bacterial communities, it seems useful to associate to the simultaneous utilization of those three indexes, the parameters of systematic composition, metabolic potentiality and relative abundance of the communities. Through the proposed methodology, a first description of bacterial communities structure in lagoon sediments allows to compare their demographic patterns to those of K type.
