Such cultures can still run stably (e.g. 98% \u003cem\u003eTetraselmis\u003c\/em\u003e with 1% Rhodomonas \u0026amp; 1% \u003cem\u003eNannochloropsis\u003c\/em\u003e each; the latter never prevails, however) and can be fed and bred normally. Nevertheless, under new cultivation conditions (different lighting, etc.) it can happen that the previously \"suppressed\" species finally prevails and at some point, for example, only \u003cem\u003eNannochloropsis\u003c\/em\u003e is cultivated.\u003c\/p\u003e\n\n\u003cp\u003e Especially when cultivating sensitive phytoplankton species, it can be useful to start with sterile cultures.\u003c\/p\u003e","brand":"Coralaxy","offers":[{"title":"Default Title","offer_id":44796892217598,"sku":"52-002-231224","price":99.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/5345\/9454\/products\/17434.jpg?v=1710241309","url":"https:\/\/coralaxy.live\/en\/products\/sterilkultur","provider":"Coralaxy","version":"1.0","type":"link"}
