The current publication comprises 15 chapters, including techniques for isolating microorganisms from various sources and assessing their growth, as well as analyses of air, soil, and water microbes. Designed to assist graduate and postgraduate students in microbiology, biochemistry, and biotechnology, this text offers practical instruction on procedures outlined in their course syllabi. To facilitate comprehension, the authors have provided flowcharts and diagrams alongside the instructions. They anticipate that this resource will be beneficial in helping students perform the laboratory assignments required in their coursework.
