FTIR Spectral and Microarchitectural Analysis of Cellulose Produced by Lactococcus lactis Under Agitated Condition

Journal of Pure and Applied Microbiology, 2017
The demand for cellulose is accelerating in the paper making industry. Alternate sources of cellulose has to be traced in order to reduce the demand for plant cellulose. Hence, in this study bacterial cellulose has been chosen as an option. In this study,

Bacterial Cellulose for Osmometer Membranes [PDF]

Nature, 1946
IN the investigation of the mechanism of polymerization reactions, it is essential to be able to count the number of polymer molecules produced. This implies that the number average molecular weight has to be measured. The best method is to use an osmometer, taking precautions with regard to the extrapolation of measurements to infinite dilution ...

Ultrasound‐assisted swelling of bacterial cellulose [PDF]

Engineering in Life Sciences, 2017
AbstractBacterial cellulose (BC) was obtained by static cultivation using commercial BC gel from scoby. BC membranes (oven dried and freeze‐dried) were swelled with 8% NaOH, in the absence and in the presence of ultrasound (US), for 30, 60, and 90 min. The influence of swelling conditions on both physico‐chemical properties and molecules entrapment was
