“…The microalgae cultured in the BBM control showed a protein content of 37.2%, almost 2-fold higher than the value for the BBM + DC (20.0%). The reduced protein content in C. vulgaris cultured in BBM + DC is most likely due to a redirection of available energy towards processes such as osmoregulation rather than towards the synthesis of proteins (Lawton et al, 2015;Matos et al, 2017).…”

“…In an open raceway ponds system, two key factors determine the suitability of a microalga for biomass production: the areal productivity (the amount of biomass per unit area (m 2 ) per unit time (day)) (Lawton et al, 2015) and the biochemical composition (Batista et al, 2013;Tibbetts et al, 2015). The microalgae commonly cultivated in raceway ponds include Nannochloropsis sp., Chlorella sp., Tetraselmis sp., Arthrospira (Spirulina) platensis, Dunaliella salina, Scenedesmus sp.…”

In this study, we investigated the outdoor production of a microalga C. vulgaris cultured in two different media under autotrophic cultivation: Bold Basal Medium (BBM) as the control and BBM supplemented with desalination concentrate (BBM + DC) using open raceway ponds (8 m 2). Data were collected on the growth, biomass productivity and biochemical composition. The culture developed in BBM + DC showed a biomass productivity of 6.8 g m-2 day-1 , while for the BBM control it was 8.5 g m-2 day-1. Intracellular protein was the main algal component (~28.6%), followed by carbohydrate + fiber (~26.0%) and lipids (~5.0%). The predominant fatty acids were mainly α-linolenic (~19.5%), palmitic (~16.5%) and linoleic (~10.0%) acids. This study demonstrates the feasibility of culturing C. vulgaris in an alternative medium based on DC in order to valorize the desalination wastewater through its application to algal mass production.

“…Soil quality is an important factor for sustaining plant and animal productivity, maintaining/ enhancing water and air quality, and supports the life of people on the earth, now and in the future. Traditional strategies for improving soil quality includes increasing physical properties like aggregation or optimizing particle size distribution (Herrick et al 2001), lowering salinity (Lawton, 2015;Kalliola et al, 2016), adjusting extremely low or high pH to more neutral values, increasing plant coverage (Laird and Chang, 2013) and enhancing microbial community activity in the rhizosphere (Lamers et al, 2012;Wang et al, 2013).…”

Petroleum and petrochemical hydrocarbons for some places are serious sources of environmental pollutants. To remediate these contaminants, phytoremediation, a relatively low cost and an environmental friendly technique is recommended more widely, now more than ever. Successful and effective applying of hydrocarbons phytoremediation depends mainly on the soil and plant types and conditions and microbial activities and the interactions between these three factors. Although for the last several decades, various plant and organism's species for the phytoremediation processes have been extensively studied, evaluating and characterizing soil properties, as an important objective for sustainable remediation and land use management, which had negligible considerations. An ideal soil for phytoremediation should have proper physical, chemical and biological characteristics to let the plant grow well and produce biomass as high as possible. It also should provide favorable conditions for microbial activities to perform efficient remediation. Soil physical characteristics such as texture, structure, water status and aeration are important factors affecting the microbial activities and consequently the degree of remediation potential. A better understanding of soil physical properties in conjunction with proper soil-plant-microbe management could be exploited to enhance the remediation of hydrocarbon contaminated soils and thus sustainable healthy environment.

“…Several researches have proposed the use of nutrient limitation as an effective strategy to increase lipid accumulation. Various cultivation conditions such as nutrient stress (Griffiths et al 2014), high light intensity, temperature (Roleda et al 2013), and salinity stress (Lawton et al 2015) were observed to increase the lipid content in microalgae. Under these stress conditions, many microalgae respond by significantly increasing the lipid content capacities, commonly ranging from 30 to 60 % of the dry cell weight (Hsieh and Wu 2009).…”

“…Surprisingly, under nutrient stress conditions, many microalgae species can accumulate both starch and triacylglycerol (TAG) enabling microalgae to endure these adverse conditions (Griffiths et al 2014;Lawton et al 2015). During nutrient stress conditions, the cell growth slows down and syntheses of new membrane compounds are reduced.…”

Untreated wastewaters have been a great concern and can cause major pollution problems for environment. Conventional approaches for treating wastewater involve tremendous capital cost, have major short comings and are not sustainable. Microalgae culture offers an interesting step for wastewater treatment. Microalgae serve the dual purpose of phycoremediation along with the production of potentially valuable biomass, which can be used for several purposes. The ability of microalgae to accumulate nitrogen, phosphorus, heavy metals and other toxic compounds can be integrated with wastewater treatment system to offer an elegant solution towards tertiary and quaternary treatment. The current review explores possible role of microalgal based wastewater treatment and explores the current progress, key challenges, limitations and future prospects with special emphasis on strategies involved in harvesting, boosting biomass and lipid yield.
