376-381The
potentials of white-rot fungi namely Coriouls versicolor NRRL 6102, Phanerochaete
chrysosporium NRRL 6359, P. chrysosporium NRRL 6361 and P. chrysosporium NRRL
6370 are evaluated for brightness of banana waste. The banana fruit stalk is
used as a sale carbon source under sterilized solid state fermentation (SSF) at
35°C for one month. Of these, P. chrysosporium NRRL 6370 cultured supported maximum
brightness (30.5 per cent than under control 117.8 per cent). This fungus
degrades lignin and hemicellulose with does not effect on cellulose fibres
(55.4 per cent than under control 40.01 per cent). The three useful types of
paper are prepared from biopuling banana fruit stalk. The two types of them are
bleached by hydrogen peroxide (writing and printing 40 SoR and greasy
paper 80-82 SoR). While the board is prepared from unbleached
biopulping in 25 SoR. The strength properties of biopulping
increases from 15-20 per cent for the hand-made sheet. Also the brightness is
higher,. i.e., > 20 per cent than under control. Results show that biopulping
controls yield and avoids losses in viscosity and strength properties
