MICROBIAL RESPONSE TO PLANTS' ROOTS AND HYDROCARBON CONTAMINANTS IN DIESEL-OIL IMPACTED TROPICAL SOIL

Adieze, Ifechukwu E.^*, Onogbou, C. D., Ihejirika, C. E., Nwabueze, R. N.

Microbial response to plants' roots and contaminants in diesel-oil impacted soils were assessed in a greenhouse study. Two plants, Pueraria spp. and Panicum maximum were planted in 6% w/w polluted and control soil samples to obtain contaminated planted and uncontaminated planted pots. Contaminated control and uncontaminated control pots were also maintained. Periodically, from week zero to 8 ...

A preliminary investigation on the emergence of antibiotic resistant bacteria resulting from inappropriate use of antibiotics in the purification of Algal cultures

Peekate, L. P.^*, Abu, G. O

Cultures of algal species are often needed for research purposes. These cultures are frequently accompanied by bacteria that are picked up from the environment together with the algal cells, thus the practice of purifying algal cultures using antibiotics. Water sample from fish pond having algal bloom was inoculated into BG-II medium supplemented with 62.5 μg.ml-1 Chloramphenicol and 100 μg.ml-1 N...

Mbachu, I. A. C^*

Rhodobacter Sphaeroidesw as isolated from four environmental samples, lake, mud, soil andstream by specific enrichment. Identification of the isolate by cultural characteristics, Gram stain, sugar fermentations and sulfide oxidation showed that it is Rhodobacter Sphaeroidesby Bergey'scriteria. R. Sphaeroidescan produce hydrogen gas as a product of metabolism, and previous studies have shown th...

MICROFLORA OF THE SHELLS OF READY-TO-EAT CONOPHOR (Tetracarpidium conophorum) NUTS ON RETAIL SALE IN OWERRI

Emeka Nwabunnia^*, Chiotna C. Otogbor

A study was undertaken to determine the bacterial population and diversity of the shells of ready-to-eat conophor (Tetracarpidium conophorum ) nuts retailed in Owerri, Imo State, Nigeria. Fifty samples (5 nuts per sample) of ready-to-eat conophor nuts were purchased from 50 retailers in Ekeonunwo market (EM), Okigwe road motor park (ORMP), Arugo motor park (AMP), New market (NM) and Relief mar...

COMPARATIVE ASSESSMENT OF HARVESTED RAINWATER QUALITY FROM DIFFERENT ROOFING MATERIALS IN PETROLEUM PRODUCING COMMUNITY, EGBEMA, RIVERS STATE, NIGERIA

Gwuorah, A.U.^*, Egbu, A.U, Eze, M.U., Nwaugo, V.C.

A comparative study of the quality of rain water from different roofing materials was carried out in Egbema, an oil producing community in Rivers State. While SO4, P04, NO3, turbidity and hardness of the rain water samples were more in asbestos and concrete roofs, the metallic ions, Zn, Fe, Al. Mn and Pb were statistically (p=0.05) more in corrugated iron and aluminum roofs which also had high...

EFFECT OF ESSENTIAL OILS FROM THE LEAVES OF Ocimum gratissimum, Callistemon rigidus, peels of Citrus paradisi and extract of C. paradisi seeds on Staphylococcus SPECIES FROM CLINICAL SPECIMENS.

Ndubuisi F.N.^*, Axjinde B.A., Eiiabulele O.Ι

Essential oils from grapefruit (Citrus paradisi), scent leaf (Ocimum gratissimum) and bottle brush (Callistemon rigidus) were obtained by steam distillation. Hot water extract of the grape seed was also obtained. They were screened for antimicrobial activity against 115 clinical isolates of Staphylococcus spp and a locally isolated antibiotic sensitive strain of S. aureus using the agar-well diffu...

DIVERSITY OF POLYAROMATIC HYDROCARBON UTILIZING MICROBES IN AN ABANDONED CRUDE OIL POLLUTED FARMLAND

Anekzue E. C^*, Chikere C. B

Polvcyclic aromatic hydrocarbons (PAHs) are hydrophobic organic compounds known to he highly toxic and recalcitrant in the environment and are present in hydrocarbon contaminated soil and sediment. This study was investigated to selectively ascertain the prevalence of anthracence utilizing microbes in a chronically polluted site. Samples were collected from crude oil contaminated sites in Obag...
