Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The orthogonal matrix method with three factors each at three levels was employed to optimize the extraction of polysacchride from Bombyx batryticatus. Optimization results show that the optimum ultrasonic treatment time was 50 min, extraction temperature 100°C and extraction time 1 h. The effects of different granularity on extraction were comparatively studied. The results showed that with the optimized condition the Bombyx batryticatus milled through 160 size mesh produced optimal results, whose polysaccharides content reached high up to 11.55±0.69 mg/g. Content changes of polysaccharides were also investigated in the silkworm bodies after surface inoculation by Beauveria bassiana. The results showed that polysaccharides content had increased significantly from 2.07±0.24 up to 11.84±0.44 mg/g during 7 days.
