Waste to wealth: circular approaches for microbial pigment production.
Review in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The increasing demand for natural and sustainable colorants has accelerated interest in microbial pigments as alternatives to synthetic dyes. Diverse microorganisms, including bacteria, fungi, yeasts, microalgae, and actinomycetes, produce pigments such as carotenoids, melanins, prodigiosin, violacein, and phycobiliproteins with applications in food, pharmaceuticals, cosmetics, textiles, and biomedicine. Despite their potential, large-scale microbial pigment production remains constrained by high costs, refined substrate dependency, and downstream processing challenges. This review summarizes recent advances in microbial pigment production using agro-industrial residues, food processing wastes, lignocellulosic biomass, and other organic waste streams within a circular bioeconomy framework. Key microbial sources, waste-derived substrates, and bioprocess strategies are discussed alongside techno-economic, environmental, and regulatory considerations. Current bottlenecks and emerging approaches, including metabolic engineering, synthetic biology, and integrated biorefinery concepts, are highlighted as future directions to enhance sustainability and industrial scalability.
