AlgaXperts has cultivated select species of FFGA in municipal wastewater in both open and closed reactors. The cultivated FFGA have been harvested and processed into dry algal plugs. Algal cellulose in dry state allows for indefinite storage with no adverse effect on cellulose quality. The dry cellulose plugs can be milled and wetted into paste consistency or simply milled and used as dry powder. The method of algal production and biomass processing is proprietary.
Industries involved in manufacturing products listed below may be able to incorporate algal cellulose fibers and various grades of algal crystalline cellulose.
Following products can incorporate algal cellulose fibers to algal crystalline cellulose in manufacturing:
- Films and flexible packaging
- Compostable replacements for plastic films
- Trash bags and grocery bags
- High-quality paper and paperboard products
- Super-strong pulp
- Mineral paper
- Strong tissue products
- Wood fibre composites
- Wood panels
Following products may incorporate algal crystalline nanocellulose in manufacturing:
- Paints, varnishes, coatings
- Reinforced bio-polymer
- Synthetic fibres and textiles
- Cosmetics and pharmaceuticals
- Optical devices
- Viscosity modifiers and flow aids
- Mesoporous films and membranes
- Flexible displays
- Printed films
- Building products
AlgaXperts’ core knowledge is in phycology. We have also developed considerable knowledge base in algal bioremediation of wastewater. Based on these areas of expertise, we provide professional services including laboratory analysis of algae, cultivation studies, field investigations, algal pilot plant design-construction-operation, technical and economic feasibility studies, and algal assessment of water treatment plants.

- Sampling, microscopic identification and annotation of freshwater algal populations from ponds, lakes, and constructed environments. Standard services include use of inverted microscopy to make identifications to the highest taxonomic level possible, which will be species in many cases. At a higher level of service, identifications can be made using molecular markers and phylogenetics.
- Sampling, identification, isolation, and culture of naturally occurring algal species for industrial cultivation. We are experienced in the isolation and cultivation of all groups of freshwater eukaryotic algae. We are experienced in optimizing conditions for large-scale cultivation of eukaryotic algae.
- Lipid and cellulose extraction and quantification from eukaryotic algal biomass, as mixed collections or unialgal batch cultures. We are experienced in fatty acid analysis and production of cellulosic microcrystals
- Amplification of existing algae – We have experience in assessing and amplifying existing growth of algae at municipal wastewater treatment plants (typically FFGA dominated periphyton community). This approach developed by AlgaXperts assesses seasonal growth of different algal species and determines nutrient uptake capacity of existing growth in process units such as final settling tanks and outfall channels. Enhancement of uptake capacity is often possible by simple changes made to growth environment. Amplification of existing algae is a cost effective way to uptake low levels of residual nutrients remaining in the final effluent prior to discharge.
- Nutrient removal from treated secondary effluent – We have experience in using pond cultivation and algal turf scrubber cultivation to remove nutrients from secondary effluent.
- Oxygenation – We have developed a method of open pond algae cultivation in which high dissolved oxygen concentration water resulting from photosynthesis is captured and recirculated into the aeration zone of an activated sludge system. Recirculation helps to maintain D.O. levels at the target concentration and reduces energy consumption by allowing turning down or turning off the air blowers.
- Technical and economic feasibility study – We have prepared technical and economic feasibility study for integrating algal cultivation into existing wastewater treatment plant for carbonaceous waste and nutrient removal.
Algal Assessment of Water Treatment Plants
- Sampling, microscopic identification and annotation of freshwater algal populations in influent water supply, process basins, filter backwash, and treated storage basins. Standard services include use of inverted microscopy to make identifications to the highest taxonomic level possible, which will be species in many cases. At a higher level of service, identifications can be made using molecular markers and phylogenetics. Scanning Electron Microscope (SEM) may be used to identify algae that can not be identified with conventional microscope.
- Process evaluation to assess factors contributing to algal regrowth in water treatment plants.
