Katrin Neumann et al. have recently shown that transgenic tobacco and potato plants can accumulate high levels of cyanophycin, a possible source for poly-aspartate. This work opens the way to the future production of biodegradable plastics using a plant-based production system. Several problems need to be overcome first, such as growth retardation as a result of cyanophycin accumulating in the cytosol, and a co-production system needs to be developed for economical reasons.
卡特琳·诺伊曼等人最近表明，转基因烟草和马铃薯植株能够积累高水平的蓝藻素，这是聚天冬氨酸的一个可能来源。这项工作为未来使用基于植物的生产系统生产可生物降解塑料开辟了道路。首先需要克服几个问题，比如由于蓝藻素在细胞质中积累导致的生长迟缓，并且出于经济原因需要开发一种联产系统。
