Handbook of Culture Media for Food and Water Microbiology
(ii) Lecithinase activity (egg yolk reaction). The lecithinase reaction is weakly
positive for B. anthracis, whereas it is usually strongly positive for B. cereus and B
. mycoides. However, it should be noted that occasionally lecithinase-negative or
...

When lecithinase- forming organisms grow on a solid medium containing LV, the
lecithinase diffuses into the agar and produces zones of opalescence around
individual colonies. This reaction can be inhibited by adding certain antitoxic or ...

This medium tests for lecithinase C activity, lipase hydrolysis, lactose
fermentation and proteinase activity. Lecithinase C activity: Seen as an opacity in
the medium due to the breakdown of lecithin in the egg yolk. Lipase hydrolysis:
Seen as a ...
Egg yolk is a rich source of lecithin and this may be incorporated into agar media
in order to demonstrate lecithinase activity. Colonies that produce lecithinase
produce a halo of opalescence due to the precipitation of diglyceride which is ...

Purpose This test is performed to differentiate Clostridium perfringens from other
Clostridium spp. based on the neutralization of lecithinase C activity by the
presence of antitoxin. Principle Bacterial lecithinase breaks down lecithin in egg
yolk, ...
