The main aim of laboratory work with Escherichia coli and soil sample was to introduce students to bacterial growth in pure culture and soil microbial flora. The experiment of bacterial growth in pure culture using optical density measurement‚ plate count and DAPI direct count‚ showed that Plate Spread method was more precise to understand bacterial population growth tendency and counting generation time. During laboratory work with soil sample were

Vehicular Pollution problems in India There are three broad sources of air pollution from human activities: stationary or point‚ mobile‚ and indoor. In developing countries especially in the rural area‚ indoor air pollution from using open fires for cooking and heating may be a serious problem. Industries‚ power plants etc. are the cause of stationary air pollution. But in urban areas both developing and developed countries‚ it is predominately mobile or vehicular pollution that contributes to

Global Warming Is Debatable‚ But Global Pollution Is a Fact When we hear the term global warming we tend to think of the enormous hole in the ozone layer‚ but what it really is the earth’s average measured temperature and why it changes. Scientists explain that green house concentrations‚ solar variation‚ and volcanoes negatively affect our earth. This isn’t including the human aspects in which we are damaging our earth’s atmosphere. There are several reasons why researchers state that humans
