^aData was obtained from independent experimental replicate
^b% of eluted protein was calculated from eluted protein (μg) × 100/initial protein existed in column (μg)
^cNegative control represent to a column condition containing crude proteins without LC3 expression bait for protein of B. pseudomallei WT strain
ND represent to no determination because protein concentration could not be detected based on Bradford assay
