H YDROGEN (H 2 ) is expected to become the most sustainable and promising clean alternative fuel in the future. This study evaluated the potential of a new facultative anaerobic bacterium isolated from cow rumen to produce H 2 from sugarcane molasses. The bacterial isolate RM122 produced 451.67 ±12.14 and 387.67 ±19.23mL/L H 2 on 6% glucose and 6% molasses sugar, respectively. RM122 was characterized phenotypically, identified genotypically by 16S rRNA sequence analysis as Escherichia marmotae, and deposited in NCBI GenBank database with the accession number OP345936. H 2 production was improved to 1670.00 ±40.41mL/L by application of optimization experiments design and kinetic study. Sugarcane molasses was used as a fermentation substrate and the optimum sugar concentration was 4%, The recorded maximum hydrogen production (H max ) was 560.00±25.98mL/L with R max (maximum hydrogen production rate) of 31.43 ±2.14mL/L/h, R max (MGM) of 30.73 mL/ L/h and λ (lag phase) of 15.19h for 52.43 fermentation time. H max of 646.67 ±23.33mL/L with R max (Exp) of 35.28 ±2.65mL/L/h, R max (MGM) of 31.90mL/L/h, λ of 13.92h and R 2 of 0.9999 were obtained at the optimum pH 8. At the optimum fermentation temperature (35°C), λ of 4.12h was achieved to maximize hydrogen production to 828.33 ±21.67mL/L with R max (MGM) of 27.98mL/L/h, and R 2 of 0.9594. At the optimum inoculum size (10%, v/v), the recorded H max was 1670.00 ±40.41mL/L with R max (Exp) of 60.00 ±2.04mL/L/h and λ of 13.50h. These findings suggest using E. marmotae RM122 as a prospective biohydrogen producer from cheap agro-industrial wastes.

F USARIUM oxysporum strain F2 was isolated from the soil. It was morphologically and molecularly identified. The isolate showed promising thermotolerance characteristics. This was shown through the production of permanent proteins after 120min of pre-thermal exposure at 40°C, as detected by SDS-PAGE. On the other hand, the RAPD marker revealed higher genetic variations produced by Fusarium oxysporum than the ISSR marker. Thirteen ISSR primers yielded 137 total bands, of which 81 were polymorphic bands with a percentage of 59.12%. While 18 RAPD primers yielded 223 total bands, 141 of which were polymorphic bands with a percentage of 63.23%. Notably, elevated temperatures triggered the isolate to enhance the production of hydrolytic enzymes. Fusarium oxysporum strain F2 produced more cellulolytic and pectinolytic enzymes until 120min pre-thermal exposure at 40°C, displaying 3.262 and 1.797 (IU/mL), with corresponding percentages of activation 82.031% and 73.288%, respectively. This promising yield of cellulolytic activity could be employed in biofuel production.
