Further characterization of the biofuel was carried out using FTIR and GC-MS. Theresults indicated that octane number, calorific value, and specific gravity of the corn straw bioethanol obtainedwere significantly higher (p<0.05) compared to rice straw bioethanol. Meanwhile, no statistically significantdifference (p˃0.05) was observed in the flash point, refractive index, pH, pour and cloud points of thebioethanol produced from the two lignocellulosic substrates. Furthermore, the results reveal that pH, octanenumber, specific gravity and flash point are within the ASTM standards while refractive index, cloud and pourpoint were slightly outside the ASTM standard.

Powdered pods of Acacia nilotica wereextracted with ethanol and distilled water separately. The extracts were tested for antibacterial activities against thetest isolates using Agar Well Diffusion method. The extracts were further subjected to qualitative phytochemicalscreening to detect secondary metabolites present using standard procedures. The minimum inhibitory andminimum bactericidal concentrations of the extracts were also detected using standard procedures. Thephytochemical screening revealed certain metabolites (steroids, saponins, terpenoids, tannins, flavonoids, andalkaloids) in the ethanol and aqueous extracts, except for steroids, which were present only in ethanol extract. Theresult of the sensitivity test showed that ethanol pod extract produced the highest and least zone of inhibition againstPseudomonas aeruginosa (22 mm) and S. typhi (15 mm) respectively at 50mg/ml while the aqueous extract of thepod exhibited activity against S. typhi (20 mm) and E. coli (12 mm) at 50 mg/ml.
