*Statistical analysis was carried out to assess the significant difference between C. beijerinckii_SDR and C. beijerinckii_wildtype and the different medium compositions for each parameter. Same letter superscripts represent no significant differences between C. beijerinckii_SDR and C. beijerinckii_wildtype and across the different medium compositions.
