Effect of Starter culture on Anti-Nutritional Factors and Shelf Life of Fermented Smoked Cassava (Pupuru): An African Fermented Staple

Adeyemo, S.M*, Bamidele, K.F

Lactic acid bacteria (LAB) are widely employed in food fermentation processes for the biosynthesis of certain important products or metabolites which helps in breaking down anti-nutritional factors in some food. This study investigated the role of LAB in extending the shelf life and reduction in anti- nutritional factors of ‘pupuru’ produced with selected LAB strain with the best technological...

Effect of Different Preservatives on Microbial Load of Zobo Drink and Molecular Characterization of its Bacterial Flora

Awe, Sunday*, Abdulmumini, Shakirat Afodun

The potentials of various combinations of three preservation techniques: the use of chemical preservative (sodium benzoate), pasteurization and lime to preserve zobo drink at room temperature (28±2 ºC) were evaluated over six days. The samples were treated and stored for six days during which the proximate composition, physiochemical and microbiological properties of the zobo drink were determi...

Bioethanol Production from Bitter Yam (Dioscorea dumetorum) and Water Yam (Dioscorea alata) Peels

Banjo T.T.*, Ogbonna, C.B., Banjo, T.O., EZE, O.I

Bioethanol which is an alternative source of fuel to fossil fuels can be produced from renewable crops. However, some of these renewable feedstocks are food competitive. Hence, this study therefore investigated the production of bioethanol from bitter yam and water yam peels. Strains of Aspergillus spp and Saccharomyces cerevisiae were obtained from the Microbiology laboratory of the University...

Evaluation Of Bacterial Profile And Proximate Analysis Of Corn Waste

Obasi, Nnenna Patric*, Ayogu, C.V

Corn waste contains moisture, cellulose, hemicellulose and lignin which make it a good raw material for making substrate in the production of organic acids with the aid of bacteria. These bacteria, during metabolism are able to produce acids that can be used as solvents. The proximate analysis of corn waste (corn cob) was determined using AOAC methods. The bacteria were isolated and identified ...

Antidermatophytic Activity of Stem Back Extracts of Khaya senegalensis (Desr.) A Juss.

Abdullahi Nuhu*, Mukhtar, M.D., Bukar, A.

The high prevalence of Dermatomycoses coupled with the residual side effect associated with orthodox medicine, treatment failure and cost of the chemotherapeutics, have necessitated exploration of new avenues of controlling these diseases with the use of plant such as Khaya senegalensis which is cheap and available, so that potent and efficacious candidate drugs could be identified. Therefore, ...

Physicochemical Properties and Shelf life Stability of ‘Tybo’ Drink Preserved with Acetic acid and Sodium Benzoate

Ahaotu, I.*, Uchendu, C.G.,, Maduka, N., Odu, N. N.

Freshly prepared tybo drink has a short shelf life which could be extended using chemical preservative. In this study, 0.1 % and 0.3 % concentration of sodium benzoate and acetic acid were incorporated into tybo drink which constitute zobo drink and tigernut milk mix together in the ratio 1:1, 3:1 and 1:3. Tybo drinks without preservative were the control samples. All the products were stored a...

Microbiological Quality of Over-The-Counter (OTC) oral Drug Preparations Obtained From Some Retail Pharmacies in Katsina State, Nigeria

Mukhtar G.L.*, Mukhtar, M.D., Magashi, A.M.

Over the counter (OTC-drugs) oral preparations being classified as non-sterile pharmaceutical products are easily prone to microbial contamination. The presence of microbial contaminants in these products may cause spoilage resulting in physical and chemical changes, as well as risk of infection or potential health hazard to the patients. A study aimed at evaluating the microbiological quality ...

Aflatoxin Contamination In Some Fresh Vegetables And A Spice Sold At Samaru Market Zaria, Nigeria

Haruna, M*, Saleh, A., Dangora, D. B., Zongoma, A. M, Ali, M.

Aflatoxin is a common contaminant of agricultural produce resulting from the growth of Aspergillus species under conditions of favourable temperature and moisture. This study was conducted to assess the level of aflatoxin contamination in fresh vegetables and tamarind used on daily basis by the populace. A total of 9 different fresh vegetables and tamarind samples were randomly collected in new...

Identification Profile of Micrococcus luteus Cs Associated with Fermented Corn-Soybean Wastes-Meal

Nwachukwu Ujunwa Felicia*, George-Okafor, Uzoamaka Ogechi, Ojiogu, Doris Ada

Micrococcus spp were among the predominant organisms isolated from earlier developed fermented corn-soybean wastes meal meant for human consumption. Hence the study was aimed at identifying the Micrococcus isolates to their species level. The Micrococcus spp were first subjected to phenotypic analysis and thereafter followed by genotypic analysis using 16SrRNA sequencing method after their DNA ...

Trypanosome Infections in Tsetse Flies Caught in Selected Areas of Southern Kaduna

Anchau R.G.*, Umar Y.A, Denwe S.D, Daudu M, Abdulrahim S., Ogar M.U, Dauda H., Saminu A., Tambuwal Z.A, Rabiu A.I.

Detection of trypanosomes in selected areas of southern Kaduna; Pantaki, Kagarko LGA of Kaduna state was carried out between 2016 - 2017. One hundred and thirty-nine (139) Glossina palpalis palpalis and 69 Glossina tachinoides were dissected and examined for trypanosome infection using dissection and light examination (Olympus) microscopes. A total of 47 infections (22.6%) out of the 208 flies ...
