Summary: This research was the first to investigate the effects of Haematococcus pluvialis microalgal biomass and colour pigment astaxanthin for the enhancement of the functional characteristics of water kefir. Kefir was evaluated for physicochemical, biochemical, and lactic acid bacteria (LAB) content after fermentation using biomass (0.25%; 0.50% with and without sugar) and astaxanthin (0.50%, no sugar) for 30 h. The addition of 0.25% biomass (W1) and astaxanthin (W4) to water kefir increased the C16:0 content almost three times and the protein content increased by 58% in W2 sample. Nanopore sequencing provided thorough insights into LAB content, revealing that in kefir containing 0.50% biomass replacing sugar (W3), Liquorilactobacillus nagelii proliferated from 8.05% to 46.57% and Lactobacillus hordei increased 15 times, while 0.25% biomass addition (W2) increased Lactococcus lactis abundance 13 times. H. pluvialis biomass was found to be an alternative prebiotic source, and it increased LAB content of water kefir. [ABSTRACT FROM AUTHOR] |
