“…Previous report suggested that municipal, agricultural and industrial wastewater showed great potential for microalgal growth (Chiu et al, 2015). Though, the combined environmental benefits of wastewater treatment and microalgal CO 2 fixation provide economic incentives to society (Wang et al, 2008; Qi et al, 2017).…”

The coupling of Chlamydomonas reinhardtii biomass production for nutrients removal of Escherichia coli anaerobic broth (EAB) is thought to be an economically feasible option for the cultivation of microalgae. The feasibility of growing microalgae in using EAB high in nutrients for the production of more biomass was examined. EAB comprised of nutrient-abundant eﬄuents, which can be used to produce microalgae biomass and remove environment pollutant simultaneously. In this study, C. reinhardtii 21gr (cc1690) was cultivated in different diluted E. coli anaerobic broth supplemented with trace elements under mixotrophic and heterotrophic conditions. The results showed that C. reinhardtii grown in 1×, 1/2×, 1/5× and 1/10×E. coli anaerobic broth under mixotrophic conditions exhibited specific growth rates of 2.71, 2.68, 1.45, and 1.13 day-1, and biomass production of 201.9, 184.2, 175.5, and 163.8 mg L-1, respectively. Under heterotrophic conditions, the specific growth rates were 1.80, 1.86, 1.75, and 1.02 day-1, and biomass production were 45.6, 29.4, 15.8, and 12.1 mg L-1, respectively. The removal efficiency of chemical oxygen demand, total-nitrogen and total-phosphorus from 1×E. coli anaerobic broth was 21.51, 22.41, and 15.53%. Moreover, the dry biomass had relatively high carbohydrate (44.3%) and lipid content (18.7%). Therefore, this study provides an environmentally sustainable as well economical method for biomass production in promising model microalgae and subsequently paves the way for industrial use.

“…Algal biomass is not only a potential source of high-value bio-oils but also yields chemicals, foods, food additives, therapeutic materials and animal feeds [5]. Moreover, algal culture in wastewaters always ensure the recovery of lost nutrients [6] and during the culture water is cleaned by means of phycoremediation. Among microalgae Chlorella species are proved to be highly industrially valuable for the production of lipids and biomasses [7], tolerant to high concentrations of CO 2 [8], adaptable to various environmental conditions [9], useful in the treatment of industrial effluents [10] [11] and purification of waste-water systems [12].…”

Green algae represent the fastest producible source of biomass that has diverse uses as biofuel, food, feed-stocks and the like. The biomass is rich in oils, which can be used as biofuel and the cultivation may be used to purify water as well. Productivity and quality of algal biomass depends on species and strains as well as environmental conditions of growth. Therefore, identification of new species and strains as well as standardization of media composition and environmental conditions for optimum yield of specific products, especially oil has a high relevance in algal technological research. In this connection, biomass productivity and oil yield of a local strain of Chlorella lobophora in BBM and modified BBM media are compared. Chemical characterization of the oil and feasibility of biodiesel production from the extracted oil is also assessed. Biomass productivity and the lipid productivity of the alga in both the media are found to be significantly different (P < 0.05). Fatty acid profiling of the oil extracted from the dried algal biomass using GC-MS analysis reveals that Palmitic acid (16:0) and Oleic acid (18:1) are the major fatty acids and nutraceutically important fatty acids are also present. The oil can be effectively transesterified to methyl esters. FTIR spectroscopy confirms the quality of the biodiesel produced. As the potentials of this local algal strain for biomass production and oil yield is confirmed, further standardization of environment conditions for better oil yield and quality biomass production is progressing to optimize its value as globally competent nutraceutical and biofuel resource.

“…It could also be used for the production of liquid biofuels [18,19] and Oedogonium biomass containing Al at similar concentrations is a suitable feedstock for bioenergy and biochar production through thermal conversion techniques such as pyrolysis and gasification [20,21]. A similar rationale can be found for linking biomass production of algae for liquid biofuel production with waste water utilisation or treatment [22,23], including marine algae for coastal systems [24] Oedogonium is also a source of carotenoids with strong anti-oxidant properties [25] which, given that other commercially important algae containing bioactives have been cultured in diverse waste waters [26,27], provides further potential for high-value application. With a mean productivity of 12.1 g DW m −2 day −1 , which is the same annualised productivity when this species is cultured at large-scale integrated with waste water at industry sites [28], annual biomass yields of 44 tonnes ha −1 could be expected at scale, offering a significant source of biomass for regional applications in agriculture and bioenergy production.…”

Abstract:Conventional water treatment processes use aluminium sulphate (alum) as a coagulant in the production of potable water. While alum is an inexpensive and reliable means of treating water, the process generates waste water containing dissolved Al. This waste water is primarily dealt with via on-site retention. In this study we investigate the cultivation of the freshwater macroalga Oedogonium as a means to sequester dissolved Al from waste water from a conventional water treatment plant. Furthermore, we examine the use of CO 2 to manipulate the pH of cultivation as a means of enhancing the sequestration of Al by either increasing the productivity of Oedogonium or increasing the bioavailability of Al in the waste water. The relative bioavailability of Al under conditions of CO 2 and no-CO 2 provision was contrasted by comparing Al uptake by Diffusive Gradients in Thin Films (DGTs). Oedogonium was able to grow rapidly in the waste water (12 g dry weight m −2 day −1 ) while consistently sequestering Al. The Oedogonium-treated waste water had a sufficiently low Al concentration that it could be used in unrestricted irrigation in the surrounding region. When CO 2 was added to the waste water containing concentrations of Al up to 8 mg L −1 , there was a slight increase (~10%) in the rate of sequestration of Al by Oedogonium relative to waste water not receiving CO 2 . This was due to two concurrent processes. The provision of CO 2 increased the productivity of Oedogonium by 15% and the bioavailability of Al by up to 200%, as measured by the DGTs. Despite this strong effect of CO 2 on Al bioavailability, the increase in Al sequestration by Oedogonium when CO 2 was provided was modest (~10%). Al was sequestered by Oedogonium to concentrations below permissible limits for discharge without the need for the addition CO 2 . The cultivation of Oedogonium in waste water from conventional treatments plants can simultaneously treat waste water for re-use and provide a biomass source for value-added applications.
