A fiber-optic retroreflective turbidimeter for continuously monitoring cell concentration during fermentation

Autor: L. H. Thacker, E. F. Phares, C. W. Hancher

Publikováno v: Biotechnology and Bioengineering. 16:475-484

A fiber-optic retroreflective turbidimeter has been developed to automatically and continuously assay the cell concentration in a fermentor by measuring the turbidity of the solution as a function of the light scattered at 180° to the incident light

Publikováno v: Archives of Biochemistry and Biophysics. 33:448-458

Experimental evidence has been presented for an aerobic biosynthesis of lactate from a C2-precursor. The data indicate that the C4-dicarboxylic acids function as intermediates; oxygen is essential. The aerobic process occurs concomitantly with glycol

[1] Large-scale fermentation of Escherichia coli and recovery of transfer ribonucleic acids

Autor: E. F. Phares, C. W. Hancher, A.D. Kelmers, G.David Novelli

Publisher Summary This chapter describes a large-scale method for the fermentation of 20–25 kg batches of Escherichia coli cells by a semi-continuous fermentation scheme, and the subsequent recovery of about 50-g batches of transfer ribonucleic aci
