Abstract
The existence of lignin in lignocellulosic fibers increases the loss in breaking tenacity and elongation of fibers when they are exposed to heat and light. Delignification by sulfonation helps to remove some of the lignin from the fibers without affecting the breaking tenacity. The delignified fibers have higher resistance to heat and light exposure compared to the raw fibers. The effect of lignin on the heat and light resistance of kenaf and cornhusk fibers with three different lignin contents was studied in comparison to cotton at various periods of heat and light exposure. The changes in the breaking tenacity, breaking elongation and yellowness of the samples were studied.

We conclude that further experiments are necessary to determine whether the very strong indirect evidence for boundary segregation can or cannot be supported directly by experiments on polonium in lead-bismuth alloys.
## Abstract The influence of the residual lignin remaining in the cellulosic rich component of pretreated lignocellulosic substrates on subsequent enzymatic hydrolysis was assessed. Twelve lignin preparations were isolated by two isolation methods (protease treated lignin (PTL) and cellulolytic enz
