Primary screening of the acidification ability of lactic acid bacteria in seaweed media (SM). Each thin line represents one replicate of the total number of bacteria within species (n) used in the assay (n is mentioned in the legend). The control (uninoculated media) was tested in triplicate (n = 3). Bold lines represent the mean of each species group, and the filled colored area represents the standard deviation of all monitored acidification curves per species group
