AbstractThe study considers the economics of the oil palm (Elaeis guinensis) to rural farmers in a rural community in south-eastern Nigeria. It compares the economic benefits of all products of the oil palm industry – palm oil, palm kernel, timber, palm wine and brooms. It posits that the most important product of the oil palm to the Enugu Ezike farmer is oil palm wine. This contrasts with the view that holds palm oil and palm kernel as the chief products of the oil palm. In a study conducted in Enugu Ezike, findings reveal that annual revenue from palm wine surpasses the six-yearly income from palm oil, palm kernel and brooms together. The study employs an eclectic framework of data collection, involving oral interviews, focus group discussions, participant observation, and the use of secondary sources. The oil palm is by every standard the most economically important tree crop and proceeds from it have positively influenced the socio-economic life of the rural communities, and as a result it has improved their living conditions.

Abstract Background: High serum cholesterol is a risk factor for cardiovascular disease (CVD), leading to many fatalities. Probiotic supplementation improves health benefits by lowering serum cholesterol. African oil palm (Elaeis guineensis) wine and corn beer have been described as potential sources of probiotic bacteria, but their cholesterol lowering activity has not been extensively investigated. Therefore in this study, we isolated and characterized lactic acid bacteria with probiotic and cholesterol lowering properties from these sources.Methods: A total of fifty lactic acid bacteria (LAB) were isolated from palm wine and corn beer using de Man Rogosa and Sharpe (MRS) agar by pour plate method. Catalase negative and Gram positive colonies were considered as presumptive LAB. For probiotic properties and selection, acid and bile salt tolerance were evaluated based on viable colony count on MRS agar and cholesterol assimilation from culture media was performed by spectrophotometry. The data analysis was performed by One Way Analysis of Variance and p value< 0.05 was considered significant. The isolates with excellent cholesterol assimilation properties were selected and identified with species of morphology and biochemical analysis using API 50 CHL kit and genotypic identification by sequencing of 16 S rRNA gene.Results: Fifty isolates had morphological features similar to LAB. They were catalase negative and Gram positive colonies. Among the fifty isolates, five were considered as acid and bile tolerant (viable count exceeded 6logCFU/ml), with two isolates having excellent cholesterol assimilation property (>80%). The result obtained using API 50 CHL kit did not agree with the genotypic identification which was used to confirm the identity of the isolates as most closely related to Lactobacillus brevis ATCC (Accession No.NR116238) and Enterococcus faeccium NBRC (Accession No. NR113904).Conclusions: The two strains isolated from traditionally fermented drinks in Buea can be considered as potential probiotics. They can therefore be used to formulate food supplement needed to lower cholesterol in hypercholesterolemia patients.

Palm wine is a very important alcoholic beverage whose consumption is limited because it spoils easily. The study was designed to isolate Acetobacter aceti from palm wine, then extract, purify and characterize alcohol dehydrogenase (AD) from the A. aceti. Muller Hilton agar was used as medium for the growth of A. aceti for 48 h. The cells were harvested and subjected to ultrasonication using 500 watt ultrasonicator. Enzyme assay was carried out in both the supernatant and pellet. The enzyme was precipitated by polyethelene glycol 6000 while gel filtration was used for purifying the enzyme. The effects of pH, temperature and substrate concentration on AD were evaluated. The isolated A. aceti was gram negative, rod shaped, catalase positive, oxidase negative and was able to oxidize acetic acid to CO2 and H2O. Triton X-100 (0.3%) was the most effective concentration in solubilizing the protein (AD), while 15% polyethelene glycol 6000 was the most effective concentration for the precipitation of AD. An optimal pH of 5 was obtained with an optimal temperature of 50 °C. The most appropriate to solubilize and precipitate AD were 0.3% triton X-100 and 15% polyethelene glycol 6000 respectively, while AD activity was reduced under acidic pH, as well as for low and high temperatures.

Background: African oil palm (Elaeis guineensis Jacq.), a perennial crop that originated from Tropical rainforest of West Africa, is one of the most important economic oil crops in Nigeria providing income for rural and semi-urban folks. This study described the ethnobotany of the plant and evaluated the extent to which it contributes to the livelihood strategies of the Ikale and Ilaje speaking people of Ondo State, Nigeria. Methods: Interviews were conducted in the local language and questionnaires were administered to willing respondents. Photographs of tools/machines used in the production of palm oil and allied products were taken. Drawings of the tools were generated on site. Results: The plant is the principal source of palm oil. Major processing tools of palm oil include cracker, presser, digester, and boiling trough. Other products that are derived from oil palm parts are palm kernel oil, kernel meat (for livestock feed), kernel shells (for fuel), palm wine, broom, fish trap, and traditional soap. All these products are made using indigenous methods. They feature in medicinal preparations, traditional ceremonies and are important household commodities. Conclusions: The products derived from oil palm tree serve as means of livelihood in the study communities and are local resources used in everyday activities of the people. The indigenous production methods observed further emphasize the role these products play in the economy of oil palm product makers and sellers. Sustainable tapping of palm wine should be encouraged in order to derive maximum benefits from oil palm tree. Keywords: Ethnobotany, Economic Botany, African Oil Palm, Ondo State, Nigeria

The present study aimed to evaluate antimicrobial activity of ethanol, methanol, schnapp (40% alcohol), oil palm wine and Raffia palm wine extracts of moss species Archidium ohioense, Pelekium gratum and Hyophila involuta against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Candida pseudotropicalis. The antimicrobial activities of the alcoholic extracts were tested against selected microorganisms using agar well diffusion method. Minimum inhibitory concentrations (MIC) of the extracts were determined using standard methods. The antimicrobial test of the extracts on selected organisms revealed that the methanolic and ethanolic extracts of the mosses studied were inactive against all the bacteria and fungi screened, while the schnapp, Oil palm wine and Raffia palm wine extracts showed significant activity against the selected organisms. The minimum inhibitory concentration (MIC) value of the extracts on the test organisms ranged from 1.25 to 40 mg/ml. The study concluded that the extracts of the mosses studied contain pharmacologically active constituents which may be responsible for their antimicrobial properties.
