A comparative study of the growth of Tetraselmis sp. in large scale fixed depth and decreasing depth raceway ponds
( Elsevier Ltd , 2016 , Article)In this study, an alternative approach was proposed where excess seawater would be added only during inoculation (DD) rather than daily addition (FD). Growth and metabolite contents of Tetraselmis sp. weren't affected for ... -
A feasibility study of utilizing hydrothermal liquefaction derived aqueous phase as nutrients for semi-continuous cultivation of Tetraselmis sp.
( Elsevier Ltd , 2020 , Article)The feasibility of substituting 50% nutrients by aqueous phase liquid (APL), derived from hydrothermal liquefaction of Tetraselmis sp. biomass, in a semi-continuous cultivation of Tetraselmis sp. was studied. Growth ... -
Effect of harvesting methods on the energy requirement of Tetraselmis sp. biomass production and biocrude yield and quality
( Elsevier Ltd , 2019 , Article)A halo-tolerant Tetraselmis sp. was grown in a 100,000 L raceway pond in the Qatari desert environment. As the biomass density reached 0.679 g/L, after 7 days, five different harvesting methods (i.e., cross-flow filtration, ... -
Enzymatic pre-hydrolysis of organic fraction of municipal solid waste to enhance anaerobic digestion
( Elsevier Ltd , 2019 , Article)Enzymatic pretreatment was proposed to enhance the anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW). Enzyme cocktails were produced at laboratory scale from Aspergillus niger fermentation on wheat ... -
Factors affecting the induction of UV protectant and lipid productivity in Lyngbya for sequential biorefinery product recovery
( Elsevier Ltd , 2019 , Article)With objective to design cyanobacterial biorefinery, taking Lyngbya as a model organism, a detail sequential protocol has been developed for production of UV protectant and lipids. This study addresses ultra violet radiations ... -
Long-term semi-continuous cultivation of a halo-tolerant Tetraselmis sp. using recycled growth media
( Elsevier Ltd , 2019 , Article)In this study, a halotolerant Tetraselmis sp. was selected for 11-month outdoor semi-continuous cultivation in one sq. m raceway tank in the Qatari desert. A fraction of the culture was harvested using ferric chloride, and ... -
Microalgae harvesting by pH adjusted coagulation-flocculation, recycling of the coagulant and the growth media
( Elsevier Ltd , 2016 , Article)Coagulation-flocculation can be considered as one of the least energy intensive microalgae biomass harvesting processes. However, cost of the coagulant and biomass contamination are two critical issues that need to be ... -
Study of microbial communities and environmental parameters of seawater collected from three Tunisian fishing harbors in Kerkennah Islands: Statistical analysis of the temporal and spatial dynamics
( Elsevier Ltd , 2022 , Article)Surface seawater, collected from three fishing harbors during different seasons of the years 2015, 2016 and 2017, were assessed for physico-chemical analyses. Results showed that seawater was mainly polluted by hydrocarbons ... -
The effect of culture salinity on the harvesting of microalgae biomass using pilot-scale tangential-flow-filter membrane
( Elsevier Ltd , 2019 , Article)In this study, the effect of culture salinity (4–6% NaCl) on the harvesting of two microalgal strains (i.e., Picochlorum sp., and Tetraselmis sp.) was investigated using pilot-scale TFF membranes. The cultures of these two ...
