Dear Prof. Istadi
We would like to submit the following manuscript for consideration for publication in Bulletin of Chemical Reaction Engineering & Catalysis.
Title: Solid state fermentation parameters effect on cellulase production from empty fruit bunch Corresponding authors: Vita Wonoputri
Other authors: Subiantoro, Made Tri Ari Penia Kresnowati, Ronny Purwadi Type of manuscript: Original research articles
Description of research: In this study, we studied the fermentation condition needed for the utilisation of empty fruit bunch (EFB) as carbon source/cellulose source for cellulase production. Cellulase demand was predicted to increase further due to its ability to break down cellulose into smaller sugar units needed for bioethanol fermentation. It was predicted that economical production of second/third generation of bioethanol is highly dependent on cheaper cellulase cost that can be trigger by the use of cheaper carbon source, such as agriculture waste, during the fermentation process. One of such method is known as solid state fermentation, whereby microorganism were grown on solid substrate in the absence of free flowing water. Therefore, solid state fermentation was used to produce cellulase from the EFB waste. The operation condition, i.e. solid to liquid ratio, temperature, and pH, which produce the highest cellulase activity was investigated using two different cellulase producer organism, Trichoderma viride and Trichoderma reesei. This research provide a database for further research on utilisation of EFB for the production of added value chemical.
We believe the scope and quality of our paper meet the requirements for Bulletin of Chemical Reaction Engineering & Catalysis as we have developed a scheme to produce a biocatalyst, i.e. cellulase, from the abundant EFB waste in Indonesia. We confirm that neither this manuscript nor any parts of its content are currently under consideration or published in another journal.
Thank you in advance for considering our submission and we look forward to receiving the reviewer’s reports in due course.
Sincerely,
Vita Wonoputri
