An additional review by March 2024 focused on the works of Jiang, et al. constituting "a breakthrough in the field of metabolic engineering of natural products" due to their identification of some missing and recalcitrant enzymes of paclitaxel biosynthesis as seen in . June of this year utilized the fungus Alternaria alternata to improve paclitaxel production using a medium containing sucrose 5% (w/v) and ammonium phosphate 2.5 mM at pH 6.0. The addition of pectin also significantly enhanced the growth and taxoid yield in paper .
