The increasing requirement of food neutral biofuels demands the detection of alternative sources. The use of non-arable land and waste water streams is widely discussed in this regard. A Cyanobacterium was isolated on the area of a possible algae production side near a water treatment plant in the arid desert region al-Wusta. It was identified as Cyanobacterium aponinum PB1 and is a possible lipid source. To determine its suitability of a production process using this organism, a set of… 

Influence of light and temperature on growth and high-value molecules productivity from Cyanobacterium aponinum

Interestingly, this strain also had the ability to accumulate other high-value compounds such as phycocyanin, zeaxanthin, and β-carotene suggesting that C. aponinum can be used for the industrial production of multiple molecules of biotechnological interest.

Detection of weed algae in open pond cultures of Cyanobacterium aponinum using PAM

The potential use of non-arable land in the al-Wusta region of the Sultanate of Oman for the production of algae biomass was examined and a detection limit of one weed algae cell in a hundred cells was achieved.

Stoichiometrically balanced nutrient management using a newly designed nutrient medium for large scale cultivation of Cyanobacterium aponinum

The first commercial nutrient medium for Cyanobacterium aponinum is developed and a process for large scale cultivation of cyanobacteria is established by combining economical medium, pre-emptive nutrient feeding strategy, and semi-continuous mode of cultivation.

Responses of a new isolated Cyanobacterium aponinum strain to temperature, pH, CO2 and light quality

A new strain of cyanobacteria was isolated from seawater samples collected near Jimo hot springs, Qingdao, China, and was identified as Cyanobacterium aponinum by 16S rDNA analysis. This study

Open pond cultures of indigenous algae grown on non-arable land in an arid desert using wastewater

The algae production on non-arable land in the al-Wusta region of the Sultanate of Oman was evaluated and weed algae, mainly Cyanobacteria and diatoms were detected microscopically in all cultures by the first to seventh day of growth.

Changes in chlorophyll fluorescence parameters during desiccation and osmotic stress of Hassallia antarctica culture

Hassallia antarctica is a terrestrial cyanobacterium colonizing various habitats in Antarctica such as soil surface, microbiological mats and seepages. H. antarctica represents one of the

Optimization of freshwater microalgal biomass harvest using polymeric flocculants

In the present study, 15 polyelectrolytes were tested for their potential to harvest algal biomass and the biocompatibility of an efficient flocculant was tested in a recycling experiment over a period of 8 weeks.

Secretomics: a biochemical footprinting tool for developing microalgal cultivation strategies.

The secretomes-based footprinting tool is the first comprehensive growth study of exometabolite at the molecular level at variable biomass densities and may be utilized in analyzing and directing microalgal cultivation strategies and reduction in overall operating costs.

Isolation and Characterization of New Temperature Tolerant Microalgal Strains for Biomass Production

In this study 130 environmental samples collected in Germany, Spain, Italy and Portugal were investigated for fast growing thermotolerant photosynthetic species and molecular identification revealed that the isolates were all chlorophytes belonging to four different families.



NaCl induced metabolic changes in the diazotrophic cyanobacterium Anabaena cylindrica

NaCl induced changes in fatty acid composition and nitrogenase, glutamine synthetase (GS) and nitrate reductase (NR) activities have been studied in a diazotrophic cyanobacterium Anabaena cylindrica.

Synechococcus sp. Strain PCC 7002 Transcriptome: Acclimation to Temperature, Salinity, Oxidative Stress, and Mixotrophic Growth Conditions

Global transcriptome profiling via RNAseq has been used to perform a comparative and integrated study of global changes in cells grown at different temperatures, at different salinities, and under mixotrophic conditions, when a metabolizable organic carbon source was present.

Characterization of PSII photochemistry in salt-adapted cells of cyanobacterium Spirulina platensis.

It is suggested that modifications in PSII photochemistry in salt-adapted Spirulina cells maintained a high conversion efficiency of excitation energy, such that no significant change was observed in either the trapping flux or the electron transport flux per PSII reaction centre.

There is overwhelming evidence that microalgae would be the logical source of oils for biodiesel production, the best option for CO2 sequestration and numerous other applications, but when extrapolating volumetric rates from laboratory or small- scale outdoor cultures to large-scale outdoor areal production rates, it becomes apparent that many of the potential claims are either misleading or still only a dream.

Genetic engineering of the unsaturation of fatty acids in membrane lipids alters the tolerance of Synechocystis to salt stress.

The role of unsaturated fatty acids in membrane lipids in the tolerance of the photosynthetic machinery to salt stress was studied and it appears that the activity and synthesis of the Na+/H+ antiporter system might be suppressed under high-salt conditions and that this effect can be reversed, in part, by the unsaturation of fatty acid in membranes lipids.
