Unlocking Streptomyces spp. for Use as Sustainable Industrial Production Platforms by Morphological Engineering 下载免费PDF全文
Gilles P. van Wezel Preben Krabben Bjrn A. Traag Bart J. F. Keijser Rob Kerste Erik Vijgenboom Josef J. Heijnen Barend Kraal 《Applied microbiology》2006,72(8):5283-5288
Filamentous actinomycetes are commercially widely used as producers of natural products (in particular antibiotics) and of industrial enzymes. However, the mycelial lifestyle of actinomycetes, resulting in highly viscous broths and unfavorable pellet formation, has been a major bottleneck in their commercialization. Here we describe the successful morphological engineering of industrially important streptomycetes through controlled expression of the morphogene ssgA. This led to improved growth of many industrial and reference streptomycetes, with fragmentation of the mycelial clumps resulting in significantly enhanced growth rates in batch fermentations of Streptomyces coelicolor and Streptomyces lividans. Product formation was also stimulated, with a twofold increase in yield of enzyme production by S. lividans. We anticipate that the use of the presented methodology will make actinomycetes significantly more attractive as industrial and sustainable production hosts. 相似文献

Although the flood of cell biological knowledge rises relentlessly, many databases face an uncertain future. Unless funding for essential bioinformatic resources is set in stone, the next storm may wash away the foundation of future cell biology research. 相似文献
