Società Agricola Serenissima srl produces microalgae and cyanobacteria with photobioreactor technology of the latest generation, the GWP®-II (patents WO 2011/013104 and WO 2004/074423).

This technology was studied and developed by Prof. Tredici, world-renowned luminary in the field of the study of microalgae and tenured professor of Microbiology at Florence University, and is marketed by Fotosintetica & Microbiologica S.r.l., a spin-off of Florence University.

It is an innovative patented technology that envisages the cultivation of photosynthetic micro-organisms in plastic bags, arranged vertically, which contain pure water enriched with mineral salts, and with CO2: air is continuously blown into the culture chambers, so as to achieve the dual aim of moving the water, and with it the microalgae that it contains, and of favouring the photosynthesis of chlorophyll, and eliminating the oxygen produced by the photosynthetic activity. When an adequate concentration of the culture medium is reached, the alga is separated from the water (thanks to the use of membranes of the latest generation), and the biomass is dehydrated at temperatures not exceeding 30°C (so as not to alter the active ingredients). The whole extraction procedure takes place mechanically, therefore ensuring the total purity and sterility of the end product.

The microalga thus produced therefore has a high degree of purity, maintaining all its nutrients. These characteristics are not found in most of the spirulina-based products available on the Italian market today.

To give our product even more quality, the production activity is constantly supported and monitored by our in-house biologist and, thanks to a computerised connection, by the experts at Fotosintetica & Microbiologica S.r.l., a spin-off of Florence University.

Each phase of our production is thus controlled 24 hours a day, safeguarding the absolute excellent quality of the product. This guarantees the conditions that maintain the “well-being” of our algae during their growth, which sometimes influences the constancy of quality of their nutrients.

In addition, our structure is equipped with a reserved experimental area, where we can study any evolutions in the development of the microalgae, or even new types of microalgae. For this particular feature we are included in the Erasmus community exchange project for university students from different EEC countries: microbiology students come to our structure so that they can have “on-site” experience of the real behaviour of microalgae and cyanobacteria.
