Biostimulation of Hydrocarbon-Utilizing Bacteria in Soil Amended with Spent Engine Oil Using Citrullus lanatus and Citrus sinensis Peels Agro-Wastes

Yusuf, K^*, Yahaya, S

Soil contamination by spent engine oil from mechanical parts of machines is a growing concern in many countries. Biostimulation of contaminated soil with agro-waste like Citrullus lanatus (water melon) and Citrus sinensi (orange) peels offers an environmentally friendly and cost-effective method for remediating the contaminated soil. In this study, biostimualtion of 200g soil contaminated with 20 ...

Antibiotics-resistance pattern of bacteria isolated from fish ponds in Ikorodu, Lagos State, Nigeria

Aina, O.R^*, Olaleye, O.N.

Aquacultures are practised in different water confinements which include plastic ponds, concrete and earthen and are known to harbour pathogens. In aquaculture (fish rearing) the use of antibiotics is on the increase where they are used as disease eradicators and as growth promoters. This study sought to investigate the antibiotic resistance pattern of bacteria isolated from fish ponds in Ikorodu,...

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 determined...

Microbiological and Nutritional Compositions of Garri Produced using Traditional Fermentation and Instant Mechanical Methods with and without added Palm Oil

Obi, C. N.^*, Eze, P. C, Ukoha, P. C.

Garri is a granular pre-gelatinized cassava starch with slightly fermented flavour and slightly sour taste made from grated, fermented fresh cassava tubers. It serves as staple food in many parts of Nigeria. This work studied the effect of fermentation and palm oil on the nutritional compositions of garri produced by traditional fermentation Method (TFM) and Instant Mechanical Method (IMM). Cassav...

Prevalence of Helicobacter pylori in Nigeria (2010-2023)

Mohammed O. A.^*

Helicobacter pylori the aetiologic agent of peptic ulcer, also associated with gastritis and gastric mucosa-associated lymphoid tissue lymphoma, has been reported to be prevalent in some developing countries. Taking into consideration its mode of transmission which is faecal oral, it is important for developing countries to be alert on the nation’s own prevalence, as a high rate could facilitate i...
