Full text not available from this repository. (Request a copy)Abstract
Rampant environmental pollution of the aquatic ecosystems worldwide has been posing a severe threat to the marine biota, as is evident from the sharp decline in aquatic ecosystem productivity and species diversity. The challenge faced by all growing economies worldwide is the management of wastewater containing a mix of domestic and industrial sources. Handling such mixed wastewaters and their treatment for reuse through conventional technologies is economically prohibitive. In this regard, growing diatoms in wastewater renders multiple benefits, including economical remediation, with the prospects of biofuel and value-added bioproducts. Diatoms are emerging as excellent phyco-remediation tools to bioremediate wastewaters due to their extraordinary remediation capability and unique cellular machinery. Oxygen released by diatoms during photosynthesis acts as a stimulant in bacterial proliferation, thus enhancing the organic pollutant and heavy metals degradation of wastewater. Diatom biomass produced through assimilation of wastewater nutrients is being sourced as feedstocks for a range of value-added products such as aquaculture feed, omega-3 fatty acids, immunomodulatory essential oils in nutraceutical and pharmaceutical products in addition to biofuels. This chapter discusses the advantages of integrating diatom cultivation technology with wastewater resource recovery while growing diatoms in wastewater, and comprehensively reviews various feasible downstream processing technologies for converting diatom biomass into valuable bioproducts. © 2024 selection and editorial matter, Archana Tiwari, Ashok Pandey, Pau Loke Show, Binod Parameswaran; individual chapters, the contributors.
