  • Patent number: 6268183
    Abstract: The invention discloses a two-step process for recovery of thuringiensin, comprising adsorbing the thuringiensin from fermentation broth by calcium silicate, and dissociating the thuringiensin by dibasic sodium phosphate.

  • Patent number: 6221223
    Abstract: Quantitative analysis for thuringiensin by capillary electrophoresis (“CE’) was demonstrated. CE is a suitable separation technique for thuringiensin because of its high resolution, great efficiency, rapid analysis and small consumption of sample. Tryptophan, an aromatic amino acid sharing a similar UV absorptive spectrum as thuringiensin, was used as an internal standard to avoid some inaccurate results caused by the questionable stability of purified thuringiensin. A mixed amount of tryptophan was mixed with varied amount of newly made thuringiensin standards for CE analysis. The electropherograms showed that the peak of tryptophan appeared around 8 minutes, which is 6 minutes earlier than the peak of thuringiensin. The peak area ratio between thuringiensin and tryptophan is proportional to the amount of thuringiensin in the mixture. The linear regression has been established to assess the peak area ratio that can be used to quantify the concentration of thuringiensin.
