Bacterial cellulose (BC) has recently gained much attention in the research realm for its potential applications in various fields, especially; their biomedical and cosmoceutical features are of considerable interest. These applications require BC in the film form, which can be produced only under static cultivation. The amount of BC produced in static conditions is lower compared to agitated/shaking culture conditions. In the present study, BC membranes were produced by G. hansenii PJK under static culture conditions in jar fermenters using chemically-defined medium in fed-batch cultivation. Fed-batch enhanced the BC production compared to the batch cultivation. The produced BC membranes were characterized using various techniques including field-emission scanning electron microscopy (FE-SEM), X-ray diffractometry (XRD), gel permeation chromatography (GPC), CP/MAS (13C-NMR), and Fourier Transform Infrared Spectroscopy (FTIR). The physico-mechanical characteristics of BC membranes were investigated by measuring its water holding capacity, water release rate and mechanical strength (stress-strain and elasticity). These results of production and characterization of BC membranes obtained in fed-batch cultivation will be presented in comparison to batch cultivation.
