A biological process, called BIOSOL, developed in our laboratory, efficiently reduces metals and reduces pathogenic indicator bacteria in sewage sludges in a single-stage system to levels meeting Ontario Ministry of the Environment (OME) requirements for land application of biosolids. Since the requirements for unrestricted use of compost are 10 to 50 times (depending on the metal involved) mor...

The detection of pathogenic microorganisms in aquatic environments is extremely relevant in terms of public health. As these laboratorial methodologies are usually difficult, expensive and time-consuming, they are frequently replaced by the assessment of fecal indicator bacteria, such as Escherichia coli. This study aimed to assess the presence of E. coli in fecal samples from Neotropical otter...

Background and purpose: Lactic acid bacteria (LAB) play an important role in human and other organisms life. Some of LABs kill pathogenic and other harmful microorganisms. Enterococcus are, gram-positive, catalase-negative, cocci forming, non-sporogenesis, and facultative anaerobic bacteria. This study was done to identify and isolate possible probiotic bacteria with benefits to human health fr...

BACKGROUND Bacteria used as indicators for pathogenic microorganisms in water are not considered adequate as enteric virus indicators. Surface water from a tropical high-altitude system located in Mexico City that receives rainwater, treated and non-treated wastewater used for irrigation, and groundwater used for drinking, was studied. METHODS The presence of enterovirus, rotavirus, astroviru...

A sanitary indicator has been proposed to gather informations about the presence of CFU (colony forming units) of bacteria capable of causing hemolysis of sheep blood cells, known as hemolytic bacteria, in a sewage sludge sample. A group of hemolytic, heterotrophic bacteria, which are differentiated in terms of their phenotypes and genotypes, includes many species and types. As follows from lit...
