Microalgal Fertilizer Production

Microalgae are composed of large amounts of carbohydrates, lipids, and fatty acids. Some microalgal species have extracellular polysaccharides that coat their cells. In addition to nitrogen fixation, cyanobacteria can produce growth-promoting substances, vitamins, organic acids, and antagonists, which play a key role in nutrient cycling. Microalgae, including cyanobacteria, are highly efficient at sequestration and assimilation of inorganic phosphorus to produce their biomass. They are also known for releasing some secondary metabolites such as vitamins, carotenoids, and amino acids, which help promote plant growth. Microalgal biomass may be a potential source for the production of slow-release biofertilizers. It not only improves soil fertility and plant growth but also helps to improve soil physicochemical parameters such as water-holding capacity and soil particle agglomeration. Microalgae can be cultivated in open systems or closed systems. Microalgae -based fertilizers have the potential to improve agricultural sustainability, and CD BioSciences has been providing customers with innovative and high-quality microalgal fertilizers based on extensive knowledge of marine plants, modern testing, and production techniques.

Our Services

CD BioSciences' R&D department focuses on optimizing all aspects of microalgae production and improving the biochemical and functional properties of the final product. All development work is designed to meet the specific needs of business and research partners. Our team can provide various types of microalgal fertilizer products from seawater, freshwater, or wastewater, including the following:

  • Nostoc Fertilizer Production
  • Dunaliella Fertilizer Production
  • Euglena Fertilizer Production
  • Chlorella Fertilizer Production
  • Schizochytrium Fertilizer Production
  • Micrococcus Fertilizer Production
  • Spirulina Fertilizer Production

Cutting-edge Microalgae Culture Technology

Light, temperature, and pH, as well as the concentrations and ratios of the major nutrients carbon, nitrogen, and phosphorus, limit the growth of microalgae in large-scale cultures. Our scientific department produces microalgae on a large scale using supercritical extraction, pressure or microwave-assisted extraction, ionic liquids, novel (less toxic) solvents, enzyme-assisted extraction or aqueous biphasic systems.
