Summary
Indigenous Algerian microalgae, Chlorella vulgaris and Coelastrella thermophila var. globulina, show high biomass and lipid yields for sustainable biodiesel production. Their fatty acid profiles and predicted quality meet international standards, indicating significant biofuel potential.
Area of Science:
- Biotechnology
- Renewable Energy
- Environmental Science
Background:
- Microalgae are a sustainable feedstock for biofuels, offering a solution to global warming and pollution from fossil fuels.
- Algeria possesses indigenous microalgae strains with potential for biodiesel production.
Purpose of the Study:
- To identify and analyze local microalgae strains (Chlorella vulgaris and Coelastrella thermophila var. globulina) from Algeria for biodiesel production.
- To evaluate the growth characteristics, biomass yield, and lipid content of these strains.
Main Methods:
- Molecular identification of microalgae strains.
- Cultivation and biomass yield measurement.
- Lipid content analysis and fatty acid profiling.
Main Results:
- Local Chlorella vulgaris and Coelastrella thermophila var. globulina demonstrated good growth and high biomass yield.
- Lipid content varied, with local Chlorella vulgaris reaching 31.39%.
- Fatty acid profiles indicated suitability for biodiesel, with predicted quality meeting ASTM6751 and EN14214 standards.
Conclusions:
- Indigenous Algerian microalgae strains show significant potential for sustainable biodiesel production.
- Further optimization of cultivation is needed to enhance large-scale biomass and lipid yields.

01:28Overview of Algae
The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...
01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
01:19Other Algae
The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
01:26Microbial Bioremediation of Hydrocarbons
Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
01:25Biofuels
The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
