الملخص
The lactic bacteria represent a very heterogeneous group from the phenotypic point of view.This group ischaracterized by commoncriteria: the type of Gram, the absence of catalase on theWhole production of lactic acid. The recently created genus Lactococcus includesNon-haemolytic and homofermentary streptococci Our theme is devoted to the isolation,purification and identification of lactococcus species.Fromtwosamples of goatmilkweisolated 60 isolates with a negative catalase gram-positivehomofermental profile from which 30 isolates were selected from this collection of shells basedon the resultants of the test Sherman bleu, only 15 representative isolates of the dominat floraWere fully identified by phenotypic methods.The results of the biochemical, physiological and fermentation tests carried out on isolated andPurified strains have made it possible to identify the following species:-V27, V6, V10, Lactococcusplantarum-V13, v16, Lactococcusraffinolactis-V21, v7, v33, v19, v8, Lactococcuslactissubsp. lactis-V31, v9, v25, Lactococcuslactissubsp.lactisbiovar. diacetylactis-V27, v3, Lactococcuslactissubsp. CremorisThe results of the technological aptitude assessment indicate that mostst strains exhibit goodproteolytic potency
