摘要： It is disclosed a non-naturally occurring microbial organism comprising at least one exogenous nucleic acid encoding an enzyme, or a portion thereof, selected from the group of ammonia lyase. Preferably, the enzyme is PAL3, and the at least one exogenous nucleic acid is obtained from
Arabidopsis thaliana . The non-naturally occurring microbial organism has an increased resistance to biochemical stress compared to the starting microbial organism, as induced for instance by oxidative stress or organic acid stress. Preferably, the non-naturally occurring microbial organism is a yeast and it may be used for fermenting a carbon source obtained from a ligno-cellulosic feedstock.
