“…The extraction process was repeated twice and the mix of the two supernatants was further analysed through HPLC. Quantification of individual carotenoids was performed in a Merck Hitachi HPLC equipped with UV-vis DAD detector as described by Rengel et al (2022), with a column flow rate that was maintained at 1 mL min − 1 using a RP-18 column. Carotenoid and chlorophyll detection was performed at 450 nm and the pigments were quantified using their correspondent standards.…”

Over the years, several studies have focused on integrally exploring lignocellulosic biomass to achieve satisfactory yields of different bioproducts and establish economically viable industrial processes. Among the bioproducts, levulinic acid (LA) has emerged as one of the top platform products derived from biomass, mainly owing to its expanding market economic position, which can stimulate viability and attract the attention of investors in the field. Considered a building block because of its versatile intermediate chemical structure, it can be used to synthesize many compounds with applications in fuels, pharmaceutical and cosmetics industries, food additives and solvents. The main synthesis route for obtaining LA is the degradation of cellulose via acid catalysis. In this context, lignocellulosic biomass is a promising and sustainable way of getting LA. Recent research has explored a potential path to full technological development associated with LA from various biomass and different catalysts. In this scenario, a comprehensive review concerning biomass for LA production and the challenges in the synthesis process is proposed. The primary studies conducted over the years and approaches to using and appreciating residual biomass are also discussed. This work also considers the use of technological tools to optimize the production of LA and seeks to contribute sustainable proposals still little explored, such as the intensification of the process and the use of fruit residues in the synthesis of this promising building block.

“…Natural carotenoid production is becoming increasingly popular in the food industry. Among carotenoids, β‐carotene is one of the widely distributed carotenoid and only 2% of total β‐carotene produced in the world is natural 19 . β‐carotene production by using microorganisms has been intensively studied to find an alternative way against synthetic carotenoids production.…”

Umbelopsis ramanniana was investigated to increase carotenoid production. Nine different carbon sources and six different nitrogen sources were evaluated for the maximum carotenoid production. The most effective nitrogen and carbon sources were KNO3 and lactose, respectively. Then, the optimization of medium components for enhancement of carotenoid production by Umbelopsis ramanniana was achieved using Plackett–Burman design. Box–Behnken response surface methodology was applied to further optimize carotenoid and biomass production. Carbon to nitrogen ratio, lactose concentration, and shaking speed were studied as variables in Box–Behnken design. The optimum conditions for carotenoid and biomass production were determined as 32.42 g/L of lactose concentration, 20:1 of carbon to nitrogen ratio, and shaking speed of 130 rpm. The maximum carotenoid and biomass production under optimized conditions were 1141 μg/L (β‐carotene‐Eq) and 13.14 g/L, respectively. When compared to the control fermentation, carotenoid, and biomass production were increased by about 2 and 1.3 folds, respectively.
