In this study, poly(3-hydroxybutyrate) (PHB) production from a newly isolated obligate alkaliphilic Bacillus marmarensis DSM 21297 was investigated to evaluate the ability of obligate alkaliphilic strain to produce a biopolymer. Additionally, electrospun nanofibers from B. marmarensis PHB (Bm-PHB) were generated using Bm-PHB/polycaprolactone (PCL) blend to evaluate the applicability of Bm-PHB. According to the experimental results, the metabolic activity of B. marmarensis decreased the pH of the medium by generating H+ ions to initiate Bm-PHB production, which was achieved at pH below 9.0. Regarding medium components, the addition of MgSO4 center dot 7H(2)O and KH2PO4 to the medium containing 1% glucose enhanced the amount of Bm-PHB synthesis, and an approximately 60% increase in PHB concentration was obtained in the presence of mineral salts.
