Lipoproteolytic deteriorating potential and X gene of spp. in raw goat milk.

This Research Communication describes the frequency of occurrence of , and in raw goat milk stored at 4 and 9°C, to evaluate the spoilage potential and capacity of these species and the presence of the X gene, responsible for the synthesis of metalloprotease aprX. Samples of raw goat milk stored at 4 and 9°C for 72 h were plated on CFC agar base (25°C for 48 h). The presence of , , and X gene were confirmed by polymerase chain reaction.
