Biodegradability of Banana and Plantain Cellulose Microfibrils Films in Anaerobic Conditions
Abstract
<p>Currently, cellulose microfibrils are being investigated as nanofillers for polymers to increase their biodegradability. However, until now there has been no report on their degradability by microorganisms. In this work the anaerobic degradation of cellulose microfibril films extracted from banana and plantain plant rachis residues has been studied. Samples were exposed to burial tests in nature compost during 14 days. Changes due to the degradation process were investigated by techniques as optical microscopy, tensile tests, viscosity measurements, ATR-FTIR spectroscopy, X-ray diffraction and thermogravimetric analysis. Biodegradability was higher for cellulose microfibril films extracted from banana (BCMF) than plantain films (PCMF). Growth of microorganism colonies on BCMF films and just yellowing on PCMF films was observed by microscopic analysis. New bands characteristic of aldehyde functional groups due to the breaking of β-(1,4)-glycosidic bonds were observed in infrared spectra. This breakage was also responsible for the fall-down of mechanical properties and polymerization degree. X-ray diffraction and thermogravimetric analysis showed that BCMF films were at the first stage of degradation for the used burial test times because the microorganisms only attacked the amorphous cellulose leading to a slight increase in crystallinity. In the case of PCMF films this variation remained practically invariant.</p>
