organism, this parameter did in fact vary only from 0.30–0.31 N
after D1 to 0.33–0.35 N after D7 (results not shown); therefore, it
was almost negligibly influenced by the storage time. This result
is consistent with the well-known fact that St is the microorganism
responsible for yoghurt firmness and explains why it is used in
industrial preparations in much higher enumeration than the other
lactic bacteria.
