Scheme of a systematic strategy for expression system construction of P. oxalicum. The secretory background of host was reduced by knocking out the Amy13A protein and selecting the starch as carbon source (a) (b). The promoter Pamy15A strength were further improved by overexpression the transcription activator AmyR (c) and deletion of putative depressor CreA (d)
