Abstract：Embedding a carbendazim degrading bacteria with sodium alginate (SA) and polyvinyl alcohol (PVA), the optimal embedding conditions and the efficiency of degradation after embedding were studied. The optimal SA embedding condition is that the bacteria were mixed with 2% SA (1:5) and cross-link in 4% CaCl2for 24h at room temperature. The optimal PVA embedding condition is that the bacteria were mixed with 10% PVA (1:5) and cross-link in 3% CaCl2under the same condition. After 48h activation, at pH6and 30℃, the degradation rate of SA embedding carbendazim degrading bacteria can reach 80.4%, and the degradation rate of PVA embedding bacteria can reach 76.3%.
