Abstract:
Dair y and fish isolates of Lactococcus garvieae were tested for their ability to utilize lactose and to grow in milk. Fish
isolates were unable to assimilate lactose, but unexpectedly, they possessed the ability to grow in milk. Genetic studies, carried
out constructing different vectorette libraries, provided evidence that in fish isolates, no genes involved in lactose utilization were present. For L. garvieae dair y isolates, a single system for the catabolism of lactose was found. It consists of a lactose
transport and hydrolysis depending on a phosphoenolpyruvate-dependent phosphotransferase system combined with a phospho-
