Biochemical, enterotoxigenicity and antibiogram profiles of Staphylococcus aureus isolated from intestines of snails
To evaluate the prevalence of enterotoxigenic Staphylococcus aureus in intestines of land snails and to determine the antibiogram of the isolates, samples for culture were obtained from ninety-nine different land snail species. Isolates of S. aureus were tested for enterotoxin production using the SET-RPLA and their antibiotic susceptibilities were determined by disc diffusion methods...

Utilisation of crude oil and gasoline by ten bacterial and five fungal isolates
This study investigated the abilities of ten bacterial and five fungal isolates indigenous to polluted mechanic soils to utilise and degrade crude oil and gasoline. Of all the bacterial and fungal isolates obtained in this study Pseudomonas sp. Bacillus sp. and Aspergillus sp. were found to be more predominant in the polluted mechanic soils. The growth...

Utilisation and biodegradation of atrazine and primextra
The abilities of twelve bacterial isolates to utilise atrazine and primextra and the degradation dynamics of the two herbicides in soil was determined in this study. Soil treatments were carried out in triplicates using the completely randomized blocked design. Utilisation of atrazine and primextra were determined by monitoring growth rates of the bacteria, actinomyces and streptomyces via viable counts,...
