The physiology of erythromycin biosynthesis in cyclic fed batch culture [PDF]

Microbiology, 1995
Antibiotic production in Saccharopolyspora erythraea was significantly enhanced in cyclic fed batch culture (c.f.b.c) compared to batch culture, whereas chemostat culture resulted in reduced production. C.f.b.c. allowed the specific growth rate to be varied, with time, according to an asymptotically decreasing trajectory without the necessity for ...

Defining lncRNAs Correlated with CHO Cell Growth and IgG Productivity by RNA-Seq

iScience, 2020
Summary: How the long non-coding RNA (lncRNA) genome in recombinant protein producing Chinese hamster ovary (CHO) cell lines relates to phenotype is not well described. We therefore defined the CHO cell lncRNA transcriptome from cells grown in controlled
