Abstract

ABSTRACT: Renewable fermentation feedstock from a freshly cut oil palm frond (OPF) is a promising medium for bacterial cellulose (BC) production. Herein, this study assessed its suitability as a solitary medium for the production of BC using Acetobacter xylinum 0416 in a static culture. The proximate composition and components analysis revealed up to 36.2 g/L of fermentable sugars and vital nutrients were available in OPF juice. Meanwhile, the effect of OPF juice concentration and initial pH arrangement shows that the maximum yield of BC (2.33 g/L) was obtained using 60% v/v of OPF juice concentration at initial pH 3.5 and incubated at 30℃ for 14 days. Besides, pure OPF juice showed a minimum in BC production due to the presence of inhibitory component suspected to be the lignin content. The kinetic study was elucidated for BC produced from OPF juice and compared with coconut water medium. The FT-IR and XRD spectra, and FE-SEM micrograph analysis for the BC showed the typical peaks represent in cellulose with a crystallinity index of 82.4% and threadlike microfibrils structure ranging from 35.6.5 nm to 77.5 nm. Thus, OPF juice is a solely sufficient medium that offers a positive alternative to BC production.
