This study was performed with a laboratory-scale fixed-bed bioreactor degrading a mixture of aromatic compounds (Solvesso100). The starter culture for the bioreactor was prepared in a fermentor with a wastewater sample of a care painting facility as the inoculum and Solvesso100 as the sole carbon source. The bacterial community dynamics in the fermentor and the bioreactor were examined by a con...

Green extracellular synthesis of the Fe2O3 nanoparticles by a native marine bacterium, Alcaligenes sp. strain NV06

The rate of mortality poultry as a result contaminated feeds is the increase in recent times. This study was carried out to determine level contamination, microbial loads and spoilage selected south west Nigeria. Rabiu Feeds, Caps Ayo Best Feeds Top were sampled. Standard pour plate methods used for analyses. Results obtained revealed average range total viable count, coliform counts, Staphyloc...

PAHs are widely distributed in the environment and pose a serious threat to ecological security human health. The P&A (Pseudomonas aeruginosa Alcaligenes faecalis) bacterium consortium obtained this study comes from oily sludge is reused for degradation of mixture sludge. Few articles pay attention reuse its degradation. solution efficient bacterial under different environmental conditions,...

The antibacterial activity of guava (Psidium guajava) and neem (Azadirachta indica) extracts against 21 strains of foodborne pathogens were determined--Listeria monocytogenes (five strains), Staphylococcus aureus (four strains), Escherichia coli O157:H7 (six strains), Salmonella Enteritidis (four strains), Vibrio parahaemolyticus, and Bacillus cereus, and five food spoilage bacteria: Pseudomona...

Soil microorganisms are important sources of the nitrogen trace gases NO and N2O for the atmosphere. Present evidence suggests that autotrophic nitrifiers such as Nitrosomonas europaea are the primary producers of NO and N2O in aerobic soils, whereas denitrifiers such as Pseudomonas spp. or Alcaligenes spp. are responsible for most of the NO and N2O emissions from anaerobic soils. It has been s...
