Passive air monitoring is usually done using special type of Petri dish plates known as settle plates. These culture plates are standard Petri dishes (measuring about 90 mm in diameter) that containing appropriate culture media that are opened and exposed for a given time and then incubated to allow visible colonies to develop and be […]

Quality assurance (QA) is a planned and systematic process used for evaluating and monitoring the quality and appropriateness or suitability of a product or given service. QA is related but different from quality control (QC). It is mainly geared towards finding a problem that is associated with a given product and managing it so that

Quality control (QC) is defined as a monitoring system that is used for detecting and correcting analytical errors by establishing performance limits. QC is a procedure or set of procedures intended to ensure that a manufactured product including pharmaceutical and medical products or performed services adheres to a defined set of quality criteria or meets
Untreated municipal solid wastes cause several environmental and health problems including the release of methane gas that contribute to greenhouse effect and the contamination of groundwater by the leachate released from the landfill sites. Leachate is the fluid portion of municipal solid wastes that squeezes out from the dumpsites and finds its way into groundwater

Anaerobic digestion is simply defined as the anaerobic breakdown of complex materials of animal or plant origin to simpler substances by microbes. It is the process in which complex organic matter are completely degraded to a mixture of solid and gaseous end products in the absence of oxygen and with the help of a diverse

Microorganisms are ubiquitous and they play several roles in the degradation of recalcitrant organic and inorganic materials in the environment. The degradation of these materials that constitute environmental hazards in the environment can be carried out under aerobic and anaerobic conditions; and these processes leads to the production of several environmentally-friendly substances and compounds that

Environmental & Soil Microbiology
Microorganisms are ubiquitous and are thus found everywhere including the soil. The soil no doubt is inundated with a wide variety of microorganisms including those that are pathogenic to humans, plants and animals and even microbes that are of immense industrial and economic importance to mankind and his environment. For example, the first commercial antibiotic

A host-parasite relationship is an association that exists between two organisms known as the host and the parasite, in which both organisms either derive benefit from the relationship or is harmed in the process. Microorganisms are ubiquitous, and they often exist in association with other forms of life in their ecological niches including man, plants

Environmental microbiology is the study of microbial processes in the environment, microbial communities and microbial interactions with other living organisms in the environment. Environmental microbiology is the branch of microbiology that studies the role of microorganisms in the maintenance of a healthy, quality, and sustainable environment. It is the study of the composition and physiology
