Ask the extremophiles why they do so. May be they have nothing else to do..... No. No. No, in thermophilic conditions (i.e. above 55C) one does not see so much of monomers or oligomers of carbohydrates and for the survival of these extremophiles they have to produce extracellular polymer-degrading enzymes to break these down to monomers so that it can be easily transported inside the cells.

I agree with Shirley. Note these organisms are growing under extreme conditions of nutrients availability. Hence, to summarily say that the only way to get nutrients would be by breaking down large molecules and then metabolizing these.

Dear Shirley and Jai,

Thanks for your answers. Would you please refer any references about this?

Regards,

Sherry

Dear Sharareh : One of my student got Ph.D. under my supervision on such a type of enzymes. I am attaching one of the reference for your reference:

Dear Jai,

Thanks for your kindness.
