Determining Indigenous Microalgae Species in Malakand Water Bodies for Potential Use as a Biofuel Production Source

Abstract

As a renewable energy source, microalgae have wide interest as a potential tool to produce biofuel and bioproducts. Prevailing in the local habitat, indigenous microalgae are more successful for wastewater treatment processes. Integrated microalgae-based biofuel and bioproduct production with wastewater treatment is a successful practice of modern research. This report describes the isolation and identification of 61 microalgal strains from lakes, springs, ponds, creeks, and rivers of the gigantic area of Malakand, Pakistan. Our study involves the seasonal existence of Chlorophyta in the area, with most dominant flora identified in the summer season followed by spring, autumn, and winter seasons, respectively. The highest ratio of microalgae was found in stagnant waters followed by slow-running water and running water, respectively. However, algal species were reported from all water bodies throughout the year. Commercially important genera like Chlorella, Scenedesmus, and Chlamydomonas were also reported,

Conversion of Vegetable Waste to Lipid Feedstock for Biodiesel Production Aided with Nano Catalyst Using RSM Software

“…Initially biodiesel was derived from edible oil and non-edible oil [3] by the process of transesterification. Then it was produced from algae [4]. Oleaginous organisms are able to store more intracellular fat in nitrogen limited conditions [5].…”

Optimization conditions for native microalgal strains grown on high ammonia-containing wastewater and their biomass utilization

“…Microalgae cultivation has attracted the attention of researchers because of its high photosynthetic rate of CO 2 fixation and for its ability to grow in a variety of eutrophied water which is unfit for agriculture, animal or human use. Algae do not require any arable land and are able to remove the contaminants and nutrients from wastewaters efficiently (Duffy et al 2009;Abinandan and Shanthakumar 2015;Hussain et al 2017;Hussain et al 2019). Microalgae can grow rapidly on non-arable land containing wastewa-ters, provide a good source of biomass and high-value bioproducts and biofuels (Cheng et al 2008;Savage 2012;Atiku et al 2016;Fatmei et al 2016;Shah et al 2019), as well as bio-fertilizers (Tripathi et al 2008;Garcia-Gonzalez and Sommerfeld 2016;Din et al 2017).…”
