|Lysozyme is an enzyme extracted from white egg that catalize the breakdown of
the union N-acetilmuramic and N-acetilglucosamine of bacterial wall polisaccharydes.
This litic action is highly effective agains Gram+ bacteria ( Clostridium spp
) and agains some Gram- bacteria ( E.Colli, Salmonella spp, Shigella spp, etc...) but do
not affect to lactic acid bacteria, because do not change the growth rate nor
acidification power nor enzymatic activities ( proteases, lipases, etc..)
Clostridium spp. is responsible for late bloting of
cheeses. Lysozyme makes its litic action agains the vegetative form of the bacteria and
during its spora germination phase. It is not effective agains spore forms.
