Abstract | ||||
Two new lignin products, desulfonated lignin and Lignin alkali were tested as W protectant additives to Spodoptera littoralis nucleopolyhedrovirus (SpliMNPV) in comparison with magnesium lignosulfonate, Fluorescent brightener 28, Berberine and Nu-Film. Desulfonated lignin and lignin alkali exhibited a high rate of protection to SpliMNPV (3.1 fold) compared with the other tested W lignin protectant additives. In contrast, Nu-Film did not show any rate of protection. The study recommends desulfonated lignin and lignin alkali as a natural UV protectant to be used for the improvement of virus formulations. The mechanism of the protection by lignin could be due to the dark color, which prevent penetration of the W light that inactivate the virus. The study demonstrates the potential of desulfonated lignin and lignin alkali as UV protectant additives to baculoviruses and the mechanism of protection. | ||||
