Abstract

Marine microalgae species was isolated and identified from its native condition of sea water discharge canals at the TNB Janamanjung Sdn Bhd’s coal-fired power station. The species was expected to be a robust one based on the prevalent harsh upstream conditions and processes the survived ones endured. The isolation involves streaking-plating method as well as serial dilution and liquid media culture propagation. Morphological and molecular identification were both carried out before satisfactory identification of Chlorella sp. be made. This species was later mixed with marine Isochrysis sp. with varying volumetric proportions and cultured in five separate air-lift bubbling column photobioreactors, as part of the experiment to determine which optimum volumetric culture ratio is best to fix CO 2 from the power plant. Results indicate that a more dominant ratio of Chlorella sp. 75% and Isochrysis sp. 25% by volume provide gives a better growth profile and indicates a better CO 2 fixation rates.

Highlights

MATEC Web of Conferences of utmost concern is the CO2 fixation rate by microalgae species, often expressed as grams of CO2 fixed per culture volume per culture duration (e.g. gCO2/(L.day)).there are few issues and challenges regarding algae-based fixation and one of them is low productivity

Other results from National Center for Biotechnology Information (NCBI) showed that several microalgae which were isolated from South China Sea were confirmed to be Chlorella species

Summary

Introduction

MATEC Web of Conferences of utmost concern is the CO2 fixation rate by microalgae species, often expressed as grams of CO2 fixed per culture volume per culture duration (e.g. gCO2/(L.day)).there are few issues and challenges regarding algae-based fixation and one of them is low productivity. MATEC Web of Conferences of utmost concern is the CO2 fixation rate by microalgae species, often expressed as grams of CO2 fixed per culture volume per culture duration (e.g. gCO2/(L.day)). One of the means to improve productivity is by using microalgae consortia, as it was reported to have better growth rate as it complement the metabolic activities of one another to grow and reproduce [6]. Quests on finding a robust and high fixation rate microalgae species has been one of research focuses in this biological endeavour. This work expresses some results out of the effort in identifying robust indigenous microalgae consortia from the 3 x 700 MW coal-fired Sultan Azlan Shah Power Station in Manjung, Sitiawan, Perak Darul Ridzuan (TNBJ)
