i am requested to design a reactor for hydrolysis stage as well as bioreactor for fermentation. however, i need to know the concentrations that will be suitable for microorganism to convert fermentable sugars into ABE fermentation broth. this level will help in finding resident times as well as amount of acid concentrations and temperatures.
Dear Itumeleng,
It depends on which microbial strain you are using for ABE fermentation. I don't know about the levels in g/Kg but bacterial strains can tolerate HMF/furfural 1-5 g/L, unless they are engineered ( Article Genome-wide RNAi screen reveals the E3 SUMO-protein ligase g...

)I hope it helps.

Dear Olifant
Our research group also work on this issue. We have studied effect of various biomass derived inhibitors i.e. furfural, HMF and vanillin etc on microbial growth and fermentation. We have studied E.coli, Streptomyces, Ralstonia, Rhodococcus microbes. Microbes can grow in 0.5 g/L furfural and HMF without showing any inhibition. Vanillin is most toxic for all the microbe. You can read our recent article on this issue, it will help you to design your experiment.

Thanks Mr Bhatia. I will have a look on your recent article. Any ideal how i can convert this value to g/kg without volume. Is there any correlation formula can be used in this case? actually the whole of this project is to design a reactor and concetrations of my feed is in g/kg and i will have to find resident time, however, i am guarded by concentrations of inhibitory products.
