Webcrude oil can be improved by adding requisite amount of flow improver. Johnston et al. (2009) described flow improvers or pour point depressants (also known as drag-reducing agents, DRAs) as long-chain, ultra-high-molecular-weight that reduces the level of turbulence in fluid streams. They are generally used to lower the pour WebAdditionally, random mutagenesis of high B-factor regions and directed evolution have been applied to improve enzyme stability in organic solvents (45, 46). However, targeted mutagenesis of high B-factor regions distal to the active site as a means of increasing catalytic activity toward a desired substrate has not been explored.
