Effects of acuC on the morphology and sporulation of S. spinosa, S. spinosa-ΔacuC and S. spinosa-acuC. A Scanning electron morphological observation of wild-type and mutant strains after 48 h; B The morphological comparison of wild-type and mutant strains on different solid media. The sporulation capacities of S. spinosa-ΔacuC and S. spinosa in three culture media were obviously stronger than that of S. spinosa-acuC. The S. spinosa-acuC produced only a few spores on CSM medium and almost no spores were produced on TSB and BHI medium
