Microorganisms can be genetically engineered
because their relatively large strands of genes can
be easily manipulated. As a result, microbial
pigment production can be increased in geometric
proportions through genetic engineering,
compared to the scaling up methods of chemists.
Microbes have also more versatility and
productivity over higher forms of life in the
industrial-scale production of natural pigments
and dyes. Fermentation process has been
increased by genetic engineering and further
research for nontoxic microbial pigment can make
quantum leaps in the economics of microbial
pigments
