Claims (14)
1. Werkwijze voor het verkrijgen van korrels van fototrofe micro-organismen, hetwelk werkwijze de stappen omvat van het onderwerpen van een startcultuur van fototrofe micro-organismen aan selectieve druk in een groeimedium, en het verwijderen van niet-bezinkende culturen uit het genoemde medium, terwijl culturen die bezinken binnen het genoemde medium in het genoemde medium mogen blijven.
2. Werkwijze volgens conclusie 1, waarbij de genoemde fototrofe micro-organismen algen zijn, bij voorkeur microalgen.
3. Werkwijze volgens één der voorgaande conclusies, die een cyclus van stappen omvat van het verwijderen van niet-bezinkende biomassa, totdat de genoemde culturen korrels vormen.
4. Werkwijze volgens één der voorgaande conclusies, die een cyclus van stappen omvat waarbij bezinkende biomassa selectief wordt behouden over niet-bezinkende biomassa, tot de genoemde culturen korrels vormen.
5. Werkwijze volgens één der voorgaande conclusies, die een cyclus van stappen omvat waarbij biomassa met een hogere bezinkingssnelheid selectief wordt behouden over biomassa met een lagere bezinkingssnelheid, tot de genoemde culturen korrels vormen.
6. Werkwijze volgens één der voorgaande conclusies, waarbij er naast fototrofe micro-organismen andere micro-organismen aanwezig zijn in de genoemde korrels.
7. Werkwijze volgens één der voorgaande conclusies, waarbij de genoemde niet-bezinkende culturen in de vorm van vlokken zijn.
8. Werkwijze volgens één der voorgaande conclusies, waarbij de genoemde korrels worden onderworpen aan condities die de productie van opslagverbindingen bevorderen.
9. Werkwijze volgens één der voorgaande conclusies die een deel vormt van een afvalwaterverwerkingswerkwijze.
10. Werkwijze volgens één der voorgaande conclusies die een deel vormt van de productie van op maat gemaakte chemische producten of andere verbindingen met een hoge waarde.
11. Korrel die kan worden verkregen door de werkwijze volgens één der voorgaande conclusies.
12. Korrel volgens de voorgaande conclusie, met een bezinkingssnelheid van ongeveer 20 — 100 cm/minuut.
13. Korrel volgens conclusie 11 of 12 met een densiteit van ongeveer 1030 - 1100 g/dm3.
14. Korrel volgens één der conclusies 11 tot en met 13 met een grootste dimensie van 0,02 tot 2 mm.
