Green microalga supplier specification
Nutrition BioTech is a bulk green microalga ingredient supplier and manufacturer, supplying whole-cell microalgal powder and microalgal extract with species identity, marker and assay method specified per order, produced by controlled cultivation, harvesting and drying, for B2B nutraceutical and beauty-from-within formulation.
Green microalga is a whole-cell botanical material rather than a single molecule, so identity rests on genus and species, cultivation route, cell-wall treatment and the agreed marker assay instead of a CAS number. Every lot ships with a Certificate of Analysis stating species identity, marker content, the analytical method and the assay basis.
| Ingredient name | Green microalga (microalgal biomass powder, or microalgal extract) |
|---|---|
| Synonyms | Green algae powder; green microalgal biomass; Chlorophyta biomass; microalgal powder |
| CAS number | Not applicable — a multi-component whole-cell microalgal material, identified by genus, species and cultivation route rather than by a single CAS number. Where a single standardised marker is required, that marker’s CAS number is stated on the specification sheet. |
| Molecular formula | Not applicable (multi-component biological material) |
| Molecular weight | Not applicable (multi-component biological material) |
| Assay / purity | Standardised to the agreed marker, for example total chlorophyll or total carotenoids, by UV or HPLC; the exact marker, method and specification range are confirmed per order. Grade options available on request. |
| Source / production route | Cultivated green microalga (division Chlorophyta). Genus and species, cultivation system, harvesting method, any cell-wall treatment and the drying route are confirmed per order and stated on the specification sheet. |
| Identity confirmation | Species identity is confirmed per lot; because commercial green microalgae are not interchangeable in composition, colour or sensory profile, the species should be fixed in the specification before formula lock |
| Appearance | Green to dark green fine powder with a characteristic algal odour |
| Solubility | Dispersible in water as a suspension rather than truly soluble; whole-cell powders sediment on standing. Particle size, dispersion behaviour and colour carry-over should be confirmed for the intended dosage form. |
| Sensory note | Colour and algal taste and odour transfer readily into finished formats, so taste, odour and colour fit should be checked at the intended use level before formula lock |
| Typical applications | Capsules, tablets, sticks and sachets, and greens or beauty-from-within powder blends for B2B nutraceutical manufacturing |
| Documentation | Download public specification sheet Public sheet prepared from the current product-page specification block; not a batch-specific Certificate of Analysis. Lot-specific COA and supporting records are available for qualified buyer review when appropriate. |
| Quality system | ISO 22000:2018, FSSC 22000, HACCP and GMP (certificates provided on request) |
| Supplier | Nutrition BioTech, 1601 W. Mission Blvd, Suite 103 (DL#29), Pomona, CA 91766, United States |

Specification FAQ
Does Green microalga have a CAS number?
Not applicable — a multi-component whole-cell microalgal material, identified by genus, species and cultivation route rather than by a single CAS number. Where a single standardised marker is required, that marker’s CAS number is stated on the specification sheet.
What purity is Green microalga supplied at, and by which method?
Standardised to the agreed marker, for example total chlorophyll or total carotenoids, by UV or HPLC; the exact marker, method and specification range are confirmed per order. Grade options available on request.
Is Green microalga soluble in water?
Dispersible in water as a suspension rather than truly soluble; whole-cell powders sediment on standing. Particle size, dispersion behaviour and colour carry-over should be confirmed for the intended dosage form.
How is Green microalga produced and where does it come from?
Cultivated green microalga (division Chlorophyta). Genus and species, cultivation system, harvesting method, any cell-wall treatment and the drying route are confirmed per order and stated on the specification sheet.
Published research context
Green microalgae have a substantial peer-reviewed literature on species identity, standardisation and analytical methods — the axes that matter for a whole-cell material specified by genus, species and marker assay rather than a CAS number. The studies below are provided as technical context for formulators evaluating this raw material. These entries summarise what the cited publications report. They are not claims about Nutrition BioTech material, and no health, therapeutic or cosmetic outcome is claimed or implied for any finished product. Buyers are responsible for the claims they make on their own labels and for confirming what is permitted in their market.
- Species authenticity of commercial Chlorella productsReported MALDI-TOF MS N-glycan profiling of 172 commercial Chlorella products: although 36% were labelled Chlorella vulgaris, only 9% presented an N-glycan pattern consistent with C. vulgaris, while 41% fell into one of four recurring glyco-types and 26% showed unique or rare patterns — evidence that stated species designations on commercial microalgal products frequently do not match the biomass supplied, and why species identity should be verified per lot rather than assumed from the label.Mócsai R et al. Foods. 2024;13(19):3182. PMID 39410217. DOI 10.3390/foods13193182. source
- DNA barcoding for genus- and species-level identityReported that the full nuclear ITS region, obtained by Sanger sequencing, can serve as a single molecular marker to differentiate Tetraselmis and Chlorella species, supported by alignment comparison and phylogenetic analysis — one documented route to the species-level identity confirmation on which whole-cell microalgal specifications depend.Fathy WA et al. Front Microbiol. 2023;14:1228869. PMID 37680531. DOI 10.3389/fmicb.2023.1228869. source
- Protein assay and nitrogen-to-protein conversion factorsReported protein measurements of microalgal and cyanobacterial biomass comparing the Lowry method after mechanical cell disruption, the Kjeldahl method and elemental nitrogen analysis, deriving nitrogen-to-protein conversion factors of 5.95 for Kjeldahl nitrogen and 4.44 for total nitrogen by elemental analysis, with protein at 30-55% of dry biomass — the conversion factor chosen materially changes a declared protein value.López CV et al. Bioresour Technol. 2010;101(19):7587-91. PMID 20494571. DOI 10.1016/j.biortech.2010.04.077. source
- Cell-wall disruption and carotenoid bioaccessibilityReported that ball milling at 30 Hz significantly improved in vitro carotenoid bioaccessibility (INFOGEST digestion protocol) from wild-type Chlorella sorokiniana, while milder ball-milling or ultrasound conditions were more effective for phytoene-enriched and alginate-encapsulated samples; freeze-drying and encapsulation also improved bioaccessibility relative to fresh biomass, and cis isomers were more bioaccessible than their trans counterparts.Morón-Ortiz Á et al. Food Chem. 2026;519:149627. PMID 42172752. DOI 10.1016/j.foodchem.2026.149627. source
