1. Adaptação de equipamento de geração de gases oxidantes para aplicação na desinfecção de água / Adaptation of generator oxidant gases equipament to aplication in water disinfection
Human consumption of water outside of the microbiological standards for drinking constitutes a health and disease risk factor. Through the process of infiltration in the soil, groundwater may be contaminated by the waste generated by human activity and deposited in the soil, waterways or air. The consumption of water in natura, captured in a spring, may lead

2. Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal
In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only t

3. Development and evaluation of a biosafe automatized system for treatment, recycling and discarding of clinical microbiology residues / Desenvolvimento e avaliação de um sistema automatizado biosseguro para o tratamento, reciclagem e descarte de resíduo de microbiologia clínica
In Brazil, daily, 2.3 tons of potentially contaminated cultured medium with microorganisms are discarded. The RDC 306 resolution from the Brazilian National Health Department rules out that residue must be treated prior to discart in order to reduce microbial load. Two methods were developed to evaluate the sensitivity, efficiency and ideal concentration of

4. Avaliação comparativa entre águas residuárias de serviços de saúde e águas residuárias urbanas: um estudo em Montes Claros - MG
Nowadays there is a concern regarding the waste from Healthcare Facilities, mainly related to solid waste. Nevertheless, the liquid portion of it has not been thoroughly studied so far. The disposing of the Healthcare Facilities waste water into the municipal sewage without any kind of treatment is a common practice. Currently there is a growing interest in

5. Decontamination of laboratory microbiological waste by steam sterilization.
A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were

6. Microbiological Degradation of Malodorous Substances of Swine Waste under Aerobic Conditions
Phenol, p-cresol, and volatile fatty acids (VFA; acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids) were used as odor indicators of swine waste. Aeration of the waste allowed the indigenous microorganisms to grow and degrade these malodorous substances. The time required for degradation of these substances varied according to the waste us

7. Procurement and Maintenance of Germ-Free Swine for Microbiological Investigations1
Germ-free swine were routinely procured by both hysterectomy and hysterotomy (Caesarian section). By means of light-weight portable equipment, piglets could be obtained and transported to the laboratory (without contamination) over distances in excess of 100 miles. The isolators employed in rearing were constructed of stainless steel and flexible plastic fil
