Cans of tinned food sometimes begin to bulge and lose their shape. infer what is happening inside the can. would you eat the food contained in tis can? explain your answer.

[sachin]

The answer is related to;

Mould formation and oxygen usage and lowering of pressure....

Home work hints are enough for the answer...

[mith]

Hmm, I'm dunno the answer but does bulging indicate lowering of pressure or increase?

Check out how Botulinum bacteria work (I may have the Latin ending wrong).

[canalon]

Yep Keywords would be:

Clostridium botulinum
anaerobiosis
and of course: "food spoilage"

[Nu_Crow]

some anaerobic bacterias can obtain energy directly from the "fermentation" of aminoacids in the food producing gases increasing the preasure of the can.
