High-throughput extraction of β-carotene from Blakeslea trispora based on a newly developed setup

Rapid and efficient extraction of bioactive compounds from biomass for sample analysis presents one of the major challenges in high-productive strain screening and bioprocess development. In this work, a high-throughput method based on a new setup was developed for the extraction of β-carotene from Blakeslea trispora. After the cell was completely disrupted by high-throughput machinery grinding, β-carotene was completely extracted by chloroform and dimethylsulfoxide (1:1, v/v). According to the experimental results, the newly developed high-throughput extraction (HTPE) method could simultaneously process 96 samples within 30 Min, and only 5-mL solvent was used for each sample. The sufficient extraction of β-carotene by the HTPE method, which was confirmed by the conventional reference extraction method, further demonstrated that the newly developed HTPE method was more efficient and economical than the methods developed previously for the extraction of β-carotene.
