“…Protein content was calculated using a nitrogen-to-protein conversion factor of N × 4.78 [27] and also by calculating species-specific nitrogen-toprotein conversion factors (N × k) for each species based on their individual amino acid contributions [28]. Fatty acids were extracted by methanolic HCl in-situ transesterification [29] and the corresponding fatty acid methyl esters (FAMEs) were separated and quantified by gas chromatography with flame ionization detection (Omegawax 250 column, Agilent 7890 GC-FID). Individual fatty acids, along with an internal standard (C19:0; methyl nonadecanoate, Fluka), were identified by comparing retention times to two standard mixtures (Supelco 37 and PUFA No.…”

“…Potentials of the microalgae cultivated in municipal wastewater effluent in batch and continuous mode have been reviewed. Many previous studies have reported the treatment of industrial, municipal and agricultural wastewater by micro algal culture systems (Franchino et al, 2013;Ji et al, 2013;Lau et al, 1995;Lau et al, 1998;McGinn et al, 2012;Singh et al, 2012;Srinivasan & Subramaniam, 2009;Talbot & delaNoue, 1993;Tam & Wong, 1989;Williams, 2003). Such type of schemes has significant applications in the reduction of nutrient release in associated streams by assimilatory uptake of nitrogen that in turn decreases the rate of eutrophication of receiving streams and also provides oxygen for nitrification and biological organic matter oxidation (Kothari et al, 2013;Mata et al, 2010;Park et al, 2010;Wolanski et al, 2009).…”

“…wastewater was introduced for the microalgal biomass production and could be used as a culture medium as well as a source of water. A recent report indicates that practices involve the use of algae for bioremediation (Mahapatra et al, 2014;McGinn et al, 2012;Saratale et al, 2010;Subashchandrabose et al, 2012;Yu et al, 2009). A recent report indicates that mixotrophic chlorophycean members (Chlorococcum sp.)…”

The present study investigates the possibility of integrating an existing industrial large scale biomass production with the treatment of waste water in which a mixture of organic and inorganic rich pollutants was used as a medium. This study suggests that the replacement of a defined medium with a complete mixotrophic medium gives a significant statistical difference in terms of growth parameters i.e. biomass production and specific growth rate.The green microalga C. pyrenoidosa was cultivated under different mixotrophic conditions for evaluation of biomass production. Inorganic defined fog's medium supplemented, with raw dairy wastewater led to 1.37g/L biomass production in comparison to 1.2g/L obtained with pure glucose revealing 14.16% increase. The study also involves the supplementation of raw dairy wastewater as an organic carbon source in an inorganic medium comprising municipal treated water and reverse osmosis (RO) treated wastewater and attained 2.4g/L and 1.6g/L of biomass respectively, as compared to 0.3g/L and 0.16g/L obtained in the wastewaters alone revealing 700% and 900% increase respectively. Mixotrophic regimen cells as analyzed by a 2D Fourier transform infrared (FTIR) spectroscopy for its biochemical content revealed that fog's blended raw dairy waste (RDW) regimen cells had maximum

“…Research on anaerobic digestion of micro-algal biomass goes back more than 50 years [6] and the subject has been revisited a number of times since then [7][8][9][10][11][12][13]. More recently digestion has been considered as a means of improving the overall energy balance of biodiesel production [14][15][16]; as a substrate for co-digestion to improve volumetric biogas yields in digestion of less favourable substrates [17,18], or with other carbon-rich wastes [19]; or as an adjunct to wastewater treatment [20,21].…”

Roberts, Sonia Heaven, Charles J. Banks Faculty of Engineering and the Environment, University of Southampton, Southampton, SO17 1BJ, UK (Email K.P. Roberts@soton.ac.uk, S.Heaven@soton.ac.uk, C.J.Banks@soton.ac.uk) Abstract Although digestion of micro-algal biomass was first suggested in the 1950s, there is still only limited information available for assessment of its potential. The research examined six laboratory-grown marine and freshwater micro-algae and two samples from large-scale cultivation systems. Biomass composition was characterised to allow prediction of potentially available energy using the Buswell equation, with calorific values as a benchmark for energy recovery. Biochemical methane potential tests were analysed using a pseudo-parallel first order model to estimate kinetic coefficients and proportions of readily-biodegradable carbon. Chemical composition was used to assess potential interferences from nitrogen and sulphur components. Volatile solids (VS) conversion to methane showed a broad range, from 0.161-0.435 L CH 4 g -1 VS; while conversion of calorific value ranged from 26.4-79.2%. Methane productivity of laboratory-grown species was estimated from growth rate, measured by changes in optical density in batch culture, and biomass yield based on an assumed harvested solids content. Volumetric productivity was 0.04-0.08 L CH 4 L -1 culture day -1 , the highest from the marine species Thalassiosira pseudonana. Estimated methane productivity of the large-scale raceway was lower at 0.01 L CH 4 L -1 day -1 . The approach used offers a means of screening for methane productivity per unit of cultivation under standard conditions.
