The discovery of biopigments has received considerable attention from the industrial sector, mainly for potential applications as novel molecules with biological activity, in cosmetics or if aquaculture food supplements. The main objective of this study was to increase the production of carotenoid pigments in a naturally pigmented yeast by subjecting the yeast to various cellular stresses using design of experiments. The fungal strain Rhodotorula mucilaginosa AJB01 was isolated from a food sample collected in Barranquilla, Colombia, and one of the pigments produced was β-carotene. This strain was subjected to various stress conditions, including osmotic stress using different salts, physical stress by ultraviolet (UV) light, and light stress using different photoperiods. The optimal growth conditions for carotenoid production were determined to be 1 min of UV light, 0.5 mg/L of magnesium sulfate, and an 18:6 h light/dark period, which resulted in a carotenoid yield of 118.3 µg of carotenoid per gram of yeast.

Considering that a large proportion of industrially used pigments are toxic and potentially mutagenic, with some having carcinogenic effects, it is essential to replace them as well as eliminate them from industrial effluents. The discovery of biopigments has received considerable attention from the industry sector. The main objective of this study was to increase the production of carotenoid pigments in naturally pigmented yeast by subjecting the yeast to various cellular stresses. The fungal strain Rhodotorula mucilaginosa/alborubescens AJB01 was isolated from a food sample collected in Barranquilla, Colombia, and one of the pigments produced was β-carotene. This strain was subjected to various stress conditions, including osmotic stress using different salts, physical stress by ultraviolet (UV) light, and light stress using different photoperiods. The optimal growth conditions for carotenoid production were determined to be 1 min of UV light, 0.5 mg/L of magnesium sulfate, and 18:6 h light/dark period, which resulted in a carotenoid yield of 118.3 µg of carotenoid per gram of yeast.

Abstract:Biodiesel has become more attractive in recent years because of its environmental benefits. One way to reduce the high cost of biodiesel is by lowering the cost of raw materials specially oils. Recently, much attention has been paid to the development of microbial oils through cultures of oleaginous microorganisms in inexpensive substrates as the wastewaters of some food industries and the crude glycerol from biodiesel production itself. Thus, cultivation of oleaginous yeasts in glycerolbased media is attracting great interest and natural biodiversity is increasingly explored to identify novel oleaginous species recycling this carbon source for growth and lipid production. Identification of oleaginous yeasts and the evaluation in glycerol and vinasse mixtures was employed to produce biomass enriched in microbial lipids and to remove nutrients from vinasse simultaneously. The fatty acid composition of the lipids was similar to that from plant oils and other microbial lipids therefore they can be used as raw material for feed additives and biodiesel production.
