Hi there;
I've read somewhere that growing in high temperatures is an advantage for industrial microorganisms; but unfortunately I couldn't find any reason for this in related articles!
Is there anyone to help me with this issue???
Thank you :)
if an organism can grow in higher temperature ,most of its metabolites are stable in that condition.In case of industry temperature stable bioproducts are more useful because they can withstand the harsh conditions of the industrial process.
i) By working at increased temperature in a bioprocess you lower the risk of contaminations by other organisms and reduce sterilization efforts.
ii) Often involved enzyme activites and product yields can be increased, as biomass formation is reduced.
iii) To increase the fitness of your producing organims at higher temperatures evolutive adaptation (e.g. in serial batches or continous culture) is recommended.
Dear Michael and Arunkumar;
Thank you both for your helpful answers :)
I was wondering if you would mind me introducing any reference on this issue.
Thanks :)
Little add-on:
iv) Stirring in bioreactors and the consequent power input, as well as cell growth lead to evolution of heat. Using thermo-resistant strains, that work efficiently at 40°C and more reduces cooling requirements.
v) This is even more important, when production sites are situated in hot countries (close to cheap carbon sources), e.g. southeast asia or south america.
Dear Raheleh, I have attached the book and article about thermophilic Microbes in Environmental and Industrial Biotechnology.
