The production of different species of microalgae in consortium with other micro-organisms from wastewaters may represent an alternative process, to reduce the costs, for obtaining biofuels. The aim of this study was to evaluate the influence of pre-ultraviolet disinfection (UV) in the production of lipids from biomass produced in high rate ponds. Two high rate algal ponds were evaluated: a pon...

Bloom of Dunaliella salina was observed naturally in stagnant puddles of water off Kuwait's Bubiyan Island on 4 July 2004. In order to closely monitor this bloom, alga were collected and maintained as pure culture of the locally isolated D. salina. Set of experiments was conducted to study and evaluate the optimum culture conditions required for two samples of D. salina (one locally isolated an...

Biodiesel-derived glycerol is a promising substrate for mixotrophic cultivation of oleaginous microalgae, which can also reduce the cost of microalgal biodiesel. The objective of this study is to investigate the potential of using glycerol and glucose as a complex carbon substrate to produce microalgal biomass and biochemical components, such as photosynthetic pigments, lipids, soluble carbohyd...

The green microalga Haematococcus pluvialis accumulates the red pigment astaxanthin accompanied by morphological changes under stress conditions, including nutrient depletion, continuous light and high temperature. To investigate the physiological state of the algal cells, we developed the digital image-processing software called HaematoCalMorph. The software automatically outputs 25 single-cel...

Reef-building corals depend for much of their energy on photosynthesis by symbiotic dinoflagellate algae (genus Symbiodinium) that live within their gastrodermal cells. However, the cellular mechanisms underpinning this ecologically critical symbiosis, including those governing the specificity of symbiont uptake by the host, remain poorly understood, in part because of the difficulties of worki...

introduction one of the important events that usually occur in seas and large water bodies’ concurrent with the change of season is the growth and species increase of phytoplankton. in the natural environment, this event does not result in imbalances of water ecosystems. however, pollution caused by human activities results in excessive growth and reproduction of phytoplankton and other opportu...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

provides in-depth information on various strategies and large-scale cultivation of algal biomass with updated state-of-art information and knowledge by the internationally recognized experts and subject peers in various areas of algal biofuels. Algae biofuel (Chisti, 2007) has been currently recognized as the alternative and clean energy source that attracted the interests of many researchers a...

Since increasing the NO3 and NH4 make eutrophication in waterbodies, microalgae tolerance tohigh concentrations of NO3 and NH4 and their growth in these levels indicate the bioremediationpotential of nitrogen-rich wastewaters and produce efficient algal biomass in freshwaterenvironments. To evaluate the tolerance of green algae, Scenedesmus quadricauda to different NO3and NH...
