Generation of high-yield rapamycin-producing strains through protoplasts-related techniques
Abstract Rapamycin is a 31-member ring macrolide produced by Streptomyces hygroscopicus and has many applications in clinical medicine.

520 | |a Abstract Rapamycin is a 31-member ring macrolide produced by Streptomyces hygroscopicus and has many applications in clinical medicine. In the present work, several protoplasts-related techniques including protoplasts mutation, intraspecies and interspecies protoplasts fusion were tried to improve the rapamycin productivity in S. hygroscopicus. Although mutation and fusion of different protoplasts of S. hygroscopicus did not improve the productivity of rapamycin significantly, the interspecies fusion of protoplasts of S. hygroscopicus D7-804 and Streptomyces erythreus ZJU325 could have brought about one high-yield (345 mg/L) rapamycin producer with 23.6% higher than that of the parental strain. Then, with seven mutants of S. hygroscopicus with different features and rapamycin productivities as the parental strains, only one-round genome shuffling has generated a high-yield rapamycin-producing strain with an outstanding yield of 445 mg/L. The systematic research of protoplast-related techniques has established an applicable way to generate high-yield strains from original microorganisms which can only produce low amount of expected natural products, without information of target gene clusters and gene sequences. | ||

In the present work, several protoplasts-related techniques including protoplasts mutation, intraspecies and interspecies protoplasts fusion were tried to improve the rapamycin productivity in S. hygroscopicus. Although mutation and fusion of different protoplasts of S. hygroscopicus did not improve the productivity of rapamycin significantly, the interspecies fusion of protoplasts of S. hygroscopicus D7-804 and Streptomyces erythreus ZJU325 could have brought about one high-yield (345 mg/L) rapamycin producer with 23.6% higher than that of the parental strain. Then, with seven mutants of S. hygroscopicus with different features and rapamycin productivities as the parental strains, only one-round genome shuffling has generated a high-yield rapamycin-producing strain with an outstanding yield of 445 mg/L. The systematic research of protoplast-related techniques has established an applicable way to generate high-yield strains from original microorganisms which can only produce low amount of expected natural products, without information of target gene clusters and gene sequences.

In the present work, several protoplasts-related techniques including protoplasts mutation, intraspecies and interspecies protoplasts fusion were tried to improve the rapamycin productivity in S. hygroscopicus. Although mutation and fusion of different protoplasts of S. hygroscopicus did not improve the productivity of rapamycin significantly, the interspecies fusion of protoplasts of S. hygroscopicus D7-804 and Streptomyces erythreus ZJU325 could have brought about one high-yield (345 mg/L) rapamycin producer with 23.6% higher than that of the parental strain. Then, with seven mutants of S. hygroscopicus with different features and rapamycin productivities as the parental strains, only one-round genome shuffling has generated a high-yield rapamycin-producing strain with an outstanding yield of 445 mg/L. The systematic research of protoplast-related techniques has established an applicable way to generate high-yield strains from original microorganisms which can only produce low amount of expected natural products, without information of target gene clusters and gene sequences.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Protoplast fusion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Rapamycin</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Genome shuffling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wei, Peilian</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fan, Limei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Dong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Xiangchen</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shen, Wenhe</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xu, Zhinan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cen, Peilin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied microbiology and biotechnology</subfield><subfield code="d">Berlin : Springer, 1975</subfield><subfield code="g">83(2009), 3 vom: 01.

Generation of high-yield rapamycin-producing strains through protoplasts-related techniques |
abstract |
Abstract Rapamycin is a 31-member ring macrolide produced by Streptomyces hygroscopicus and has many applications in clinical medicine. In the present work, several protoplasts-related techniques including protoplasts mutation, intraspecies and interspecies protoplasts fusion were tried to improve the rapamycin productivity in S. hygroscopicus. Although mutation and fusion of different protoplasts of S. hygroscopicus did not improve the productivity of rapamycin significantly, the interspecies fusion of protoplasts of S. hygroscopicus D7-804 and Streptomyces erythreus ZJU325 could have brought about one high-yield (345 mg/L) rapamycin producer with 23.6% higher than that of the parental strain. Then, with seven mutants of S. hygroscopicus with different features and rapamycin productivities as the parental strains, only one-round genome shuffling has generated a high-yield rapamycin-producing strain with an outstanding yield of 445 mg/L. The systematic research of protoplast-related techniques has established an applicable way to generate high-yield strains from original microorganisms which can only produce low amount of expected natural products, without information of target gene clusters and gene sequences. © Springer-Verlag 2009 |
