I've found the best way of extending shelf life of just about anything in the fridge is use a vacuum sealer (bag or container). I find cheese generally lasts at least twice as long as normal. And lemons/limes that would normally dry out in a week in the fruit bowl, last for a couple of months in vacuum bags (they go a bit soft but fine for zesting and/or juicing). Vacuum pack meat and freezer-burn is history. My vacuum packer comes second only to my Tmx as a "must have" in the kitchen.
PS You can even vacuum pack silver to stop it tarnishing!
