生物技术创业公司绿光生物科学有了不用微生物细胞就能生产化学制品的技术。生物技术学家用转基因细菌和其他转基因微生物,利用可再生来源生产生物燃油和化学物。但是这些生物中复杂的代谢通路很难被控制,而且需要的产物也许对微生物有毒。如果干脆不用活细胞会怎么样呢?波士顿地区的创业公司绿光生物科学(Greenlight Biosciences)改造不同的微生物,让它们生产多种能制造化学物质的酶,然后再打开细菌,收集这些酶。科学家不需要从其他细胞物质中分离出这些酶,
Biotech startup Green Biotech has the technology to produce chemicals without microbial cells. Biotechnology scientists use genetically modified bacteria and other genetically modified microorganisms to make bio-fuels and chemicals from renewable sources. However, the complex metabolic pathways in these organisms are difficult to control and the desired product may be toxic to microorganisms. What if it were simply not using living cells? Greenlight Biosciences, a startup in Boston, reworked different microbes to produce multiple enzymes that make chemicals and then opened the bacteria to collect the enzymes. Scientists do not need to separate these enzymes from other cellular materials,
