Standard Techniques and Methods for Isolating, Selecting and Monitoring the Growth of Microalgal Strain
The characterisation of microalgae is based on features, such as morphology, cell ultrastructure, pigments, photosynthetic products, reproduction, growth patterns, biomass and cellular proximate composition. These features are essential in identification, isolation, selection and cultivation of various microalgae for nutrition and as renewable resources, such as biofuels and biochemicals for human and animals. Although various methods have been used to isolate, select and monitor the growth of microalgal strain as described in the literature, few methods have limitations and not appropriately presented to users. Reviewing the standardised and validated methods for isolating and evaluating the characteristics of microalgae and providing a complete and simple report for the end users are necessary. This study aims to provide a complete and easily accessible guideline with all necessary standards and validated laboratory methods related to applied phycology, which can be used as reference by students and researchers who handle microalgae. In this chapter, major standard techniques for isolation and selection and calculation methods for monitoring microalgal growth are discussed with substantial number of flow charts and diagrams as the working manual in the field of applied phycology. The information provided in this chapter will be helpful for any users from the laboratory for the biomass production of commercial scale microalgae.
