Antimicrobial Activities of Bio-Oil and Bio-Tar Obtained from Pyrolysis of Cocoa Pod Husk (Theobroma Cacao L.) on Some Selected Pathogenic Organisms
Abstract
Abstract The use of synthetics antibacterial and antifungal activities of bio tar and biological oil obtained via cocoa pod husk were investigated on seven selected bacteria; Erwinia carotovora, Corynebacterium sopedonium, Staphylococcus aureus, Pseudomonas solanacearium, Salmonella typii, Xanthomonasphaseoli, Clavbactermichinganensi and five selected fungal; Phytophthora megacarrier, Fusarium vasinfectum, Collectotrichum lindinuthianum, Glomerella gossypii, Cercospora sojina isolates, employing the procedures for food poisoning and agar culture dispersion, accordingly, Findings from antimicrobial activity indicated that the bio-oil as well as the bio-tar performed reasonably well against all the isolates with a zone of inhibition ranged from19.17 ± 1.04g to 35.77 ± 0.25c mm. The results of antifungal activities showed that the percentage of mycelia growth inhibition ranged from 80.35 to 99.33% against the isolates compared to the standard Mancozeb (control). The biological oil and biotar from cocoa pods husks were pyrolyzed at 400°C and their antifungal activity was noticeably higher than their antibacterial activity.
