Mechanical Cell Disruption Technologies for the Extraction of Dyes and Pigments from Microorganisms: A Review

The production of pigments using single cell microorganisms is gaining traction as a sustainable alternative to conventional syntheses, which rely, in no negligible proportions, on petrochemicals. In addition to depending on petroleum, these syntheses involved the use of toxic organic solvents, which may be inadequately disposed of across a range of industries, thus compounding the deleterious effects of fossil fuel exploitation. Literature suggests that notable research efforts in the area of sustainable pigment production using single cell microorganisms are focused on the production of pigments coveted for their interesting qualities, which transcend their mere capacity to dye various fabrics both natural and synthetic. As interest in sustainable pigment biosynthesis grows, the need to devise effective and efficient cell disruption processes becomes more pressing given that the viability of pigment biosynthesis is not only dependent on microorganisms' yield in terms of production, but also on researchers' ability to recover them. This review chiefly reports findings as to mechanical cell disruption methods, used individually or in various combinations, and their aptitude to recover biosynthetic pigments.

Automated summary

The production of pigments using single cell microorganisms is emerging as a sustainable alternative to conventional synthesis methods heavily reliant on petrochemicals. Research is focused on producing pigments coveted for their unique qualities beyond just dyeing abilities. Efforts are also directed towards developing effective cell disruption methods to ensure successful recovery of biosynthetic pigments.
