Abstract
Description
1)容器は、処理対象の微細藻類/水溶液混合物を受容することができる。これは、水循環によりサーモスタット制御できる二重壁容器である。
2)ポンプは、システム内の混合物の循環を一定流量に調整する。
3)超音波プローブは発電機に接続されており、所望の超音波出力を固定することができる。プローブは2/3が処理される液体に浸漬され、それ自体特定の固定周波数(約20kHz)を放射する。
4)超音波反応器には2つの壁が装備されており、サーモスタット制御された水の循環により、混合物をサーモスタット制御できる。環境に超音波を送るために、超音波プローブを反応器に入れる。
5)バルブは、混合物の循環に抵抗を加えることにより、システム内での圧力を増大させることができる。超音波反応器の上流にある圧力計の圧力のこの変動を視覚的に監視することができる。
バイオマス(アルスロスピラ・プラテンシス)を、1/20の比率(つまり、20gの水溶液に対して1gのバイオマス)に従って抽出水溶液(リン酸緩衝液、pH7)と混合する。この場合、4gのスピルリナを80mLの水溶液に導入する。20℃に温度調節して、10分間、混合物を低超音波出力の超音波(30W)にさらす。システムに圧力は加えられていない。次に、抽出物を8000rpmで10分間遠心分離し、ブフナー(気孔率8μm)でデッドエンドろ過を行い、存在する可能性のある懸濁粒子を除去する。
