BACKGROUND Marine microalgae are among the most promising lipid sources for biodiesel production because they can be grown on nonarable land without the use of potable water. Marine microalgae also harvest solar energy efficiently with a high growth rate, converting CO2 into lipids stored in the cells. Both light intensity and nitrogen availability strongly affect the growth, lipid accumulation...

OBJECTIVE The aim of this study was to investigate the effects of simultaneous supplementation of laying hens with alpha-linolenic acid (ALA) resources (flax, perilla, and Eucommia ulmoides [E. ulmoides] seeds) and eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) resources (Schizochytrium sp.) on egg quality and n-3 polyunsaturated fatty acids (PUFA) profile. METHODS Dietary treatments we...

Introduction: Mixotrophic microalgae systems have great potential for bioenergy production and wastewater treatment. Anaerobic-treated wastewater supplemented with carbon can improve biomass yield and quality, as it presents low carbon content. Alternative carbon sources in microalgae cultivation, such as glycerol, are essential for minimizing the economic and environmental impacts caused by bi...

The remediation of leachate from (municipal) landfills is becoming an increasing challenge for many government authorities. There is mounting interest in using bioremediation as a means of stripping these contaminants from the leachate and concentrating it within biological material, typically microalgae. Additionally, there is significant interest in the production of lipids from waste streams...

Microalgae have great potential to be a feedstock for producing biofuel. One of the major impediments towards the industrial-scale manufacturing of biofuel from microalgae is the ineffective separation of microalgae from water. In this communication, we first carried out froth flotation tests to harvest freshwater microalgae (Chlorella sp. BR2) and marine microalgae (Tetraselmis sp. M8) from di...

oil pollutions are widespread environmental pollutants. most of the studies have been focused on the biodegradation of these pollutions. unfortunately, the information on the microflore of the polluted regions especially for microalgae is limited. in this research, we have focused on masjed soleiman; one of the most oil polluted cities in iran. soil and water samples were collected from differ...

background: microalgal lipid is a promising feedstock for biodiesel production. the aim of the present study was to investigate the effects of cultivation temperature on the growth and lipid accumulation properties of nannochloropsis oculata microalgae. methods: nannochloropsis oculatacan grow in a wide range of temperatures (5 ~ 35°c). late in the stationary growth phase of microalgae, biomass...

Microalgae biomass has garnered significant attention as a renewable energy feedstock and alternative to petroleumbased fuels. The diverse metabolism of green microalgae species additionally provides opportunities for recovery of products for feed, food, nutraceutical, cosmetic, and biopharmaceutical industries. Recently, the concept of using microalgae as part of a biorefinery model has been a...

Rising oil prices and concerns over climate change have resulted in more emphasis on research into renewable biofuels from microalgae. Unlike plants, green microalgae have higher biomass productivity, will not compete with food and agriculture, and do not require fertile land for cultivation. However, microalgae biofuels currently suffer from high capital and operating costs due to low yields a...
