Abstract (EN): Microalgae and cyanobacterial photosynthetic pigments possess immense potential for sustainable colouring applications in industries such as food, feed, cosmetics and textiles, primarily because of their vibrant colours, safety and eco-friendliness. These photosynthetic pigments align with the growing demand for eco-conscious products. However, substantial challenges persist at the industrial level, particularly in scaling up production and achieving acceptance in niche markets. This review highlights the critical roles of abiotic factors such as light quality, temperature, pH, nutrient availability and salinity in enhancing pigment production using conventional production methods. Additionally, issues related to the cost, purity and stability of the pigments must be addressed to facilitate broader acceptance. Looking forward, the focus must be on developing innovative cultivation techniques that optimise and define the abiotic conditions most favourable for maximum pigment production or even incorporate genetic engineering tools. Additionally, exploring untapped species from inhospitable environmental sources and integrating the residual biomass through biorefinery processes represent effective approaches for enhancing the sustainability of microalgae and cyanobacterial pigment production on an industrial scale. Overcoming these barriers utilising targeted research and industry collaboration as well as fostering market acceptance is essential for fully harnessing the potential of these natural pigments and driving the transition towards more sustainable industrial colouring practices.
