Scanning electron microscopy (SEM), bamboo shoot particles (BSPs) components and reducing sugar content in cultures after in vitro treatment. a–c SEM for raw BSPs; d–f SEM for BSPs in the control group; g–i SEM for BSPs after 72 h of treatment in CCJ; j–l SEM for BSPs after 72 h of treatment in XCJ; m–o SEM for BSPs after 72 h of treatment in YCJ; p amount of reducing sugar in the culture after 6 days of treatment; q cellulose, hemicellulose and lignin degradation efficiency of BSPs after 6 days of treatment. CCJ: gut symbiotic microbiota of female; XCJ: gut symbiotic microbiota of male; YCJ: gut symbiotic microbiota of larvae. Descriptive data were expressed as mean ± Standard Error of Mean; the different normal letters indicated significant difference at different developmental stage at 0.05 level (n = 3); the different capital letters indicated significant difference in different components at 0.05 level (n = 3)
