Methods of algal culturing

Jednostanične alge (mikroalge) i makroalge igraju važnu ulogu u ekologiji planeta jer su odgovorne za gotovo 45% globalne produkcije kisika te su osnova hranidbenih lanaca u vodenim ekosustavima. Ipak, vrlo je teško odrediti njihov kvantitativni doprinos ekološkoj dinamici i biogeokemijskim kruženjima. U ovome radu opisane su najčešće tehnike uzgoja algi u kulturama, te su u globalu podijeljene na tehnike izolacije mikroalgi i makroalgi. Razvijeni su različiti mediji za izolaciju i kultivaciju slatkovodnih i morskih algi, a za neke se vrste koristi agar. Kako bi se odabrao povoljan medij, potrebno je poznavati ekologiju i fiziologiju vrste. Eksperimenti sa kulturama jesu i ostat će iznimno bitni za razumijevanje važnosti i uloge algi u ekosustavu.Single – celled algae (microalgae) and macroalgae have a vital role in the ecology of the planet, being responsible of for roughly 45% of global productivity supporting food webs in water ecosystems. However, trying to quantify their contribution to ecological dynamics and biogeochemical cycles remains a daunting process for various reasons. In this work most common algal culturing techniques are presented, with the focus to isolation techniques as well as maintenance of micro- and macroalgae cultures. Various culture media, as well as agar plates have been developed and used for isolation and cultivation of freshwater and marine algae. It's important to know the ecology and physiology of each species in order to choose right medium. Experiments with cultures are and will remain crucial in a processes of understanding how algae responses to environmental variability
