Principal component analysis of t-RFLP datasets. Principal component analysis of t-RFLP datasets of the bacterial flora derived from periodic sampling of cod loins in a shelf life experiment. Labels correspond to days of storage (e.g. D6 for six days), packaging method (Air or MAP), storage temperature (0, -2 or -4°C) and salt content (low salt, LS and high salt, HS). A box has been added around the samples clustering tightly together for clarification.
