Fig. 1From: Expression of Vitreoscilla hemoglobin enhances production of arachidonic acid and lipids in Mortierella alpina Transformant verification. a Scheme for expression of vgb in Mortierella alpina ATCC 32222; b PCR analysis of transformants of Mortierella alpina. The PCR product corresponding to VHb is 441Â bp (Lanes: M, 5000Â bp marker; 1, negative control, wild-type strain ATCC 32222; 2, transformant VHb-20; 3, positive control, plasmid pBIG-CBXB-VHb; 4, transformant VHb-10); c CO binding spectra of cell extracts from original strain ATCC 32222 and transformant VHb-20Back to article page
