Large scale production of succinic acid by fermentation of sequential inorganic salt pretreated oil palm empty fruit bunch

The abundance of accumulated oil palm wastes has led to their usage as substrate in the production of organic acid such as succinic acid (SA). For the first time, oil palm empty fruit bunch (OPEFB) which was pretreated using inorganic salts was utilized for SA production in a large-scale fermenter....
