2.7. Ability of biogenic amine production
LAB isolates were grown separately in presence of the following
amino acids-histidine, tyrosine, lysine and ornithine (Marco,
Zacarías, Vinderola, Reinheimer, & Quiberoni, 2014). The amino
acids were procured from HiMedia, India. After incubation at 37 C
for 72 h, biogenic amine production was confirmed by indicator
colour changes in response to amine formation.
