a research was conducted at kauma oxidation ponds, a sewage water treatment plant found in lilongwe, malawi with an aim of establishing the efficiency of these sewage treatment ponds in treating sewage wastewater. water samples from the effluent discharging points in the maturation ponds were collected and analysed in the labouratory for, bod, coliform bacteria, total nitrogen (tn), phosphorous...

Special high-protein foods suitable for diabetics must be treated to ensure the complete absence of microorganisms and bacteria. It is also important achieve that this treatment does not change nutritional value product. Among new decontamination technologies, low-energy electron-beam has proven an effective technique inactivating bacteria with minimal impact on food quality. The paper aims ana...

The use of chemicals in food plant sanitation for removing and killing microorganisms could be reduced by the use of alternative nonchemical interventions. Supercharged negative air ionizers have shown potential to effectively reduce airborne and surface microorganisms. In our earlier studies, a small chamber, controlled at 85% relative humidity and supercharged with a −25 kV electrostatic spac...

High mortality and hospitalization rates have seen Listeria monocytogenes as a foodborne pathogen of public health importance for many years and of particular concern for high-risk population groups. Food manufactures face an ongoing challenge in preventing the entry of L. monocytogenes into food production environments (FPEs) due to its ubiquitous nature. In addition to this, the capacity of L...

Bacteriophages have been researched as a new alternative to antibiotics. These viruses inject their genetic material into bacteria and use their host machinery to multiply themselves. The research of bacteriophages in Brazil will certainly provide low-cost treatment of multidrug resistant bacteria, new microbiological diagnosis and advantages for the Brazilian food industry.
