Physical and chemical environmental factors’ influence on the proteolytic potential of probiotic microorganisms’ individual representatives
This work is devoted to the study of sanitary and hygienic monitoring of fishery water use objects in Murmansk region. The paper presents assessment of the ecological and sanitary conditions of fishery reservoirs in the Arctic region of the Kola and Tuloma rivers for the period 2016-2018 based on th...
