Current Advances in Carotenoid Production by Rhodotorula sp.

Fermentation, Journal Year: 2024, Volume and Issue: 10(4), P. 190 - 190

Published: March 30, 2024

Microbial carotenoids are pigments of lipophilic nature; they considered promising substitutes for chemically synthesized in the food industry. Their benefits human health have been demonstrated due to their antioxidant capacity. Yeasts genus Rhodotorula genotypic characteristics that allow them accumulate high concentrations carotenes under certain stress conditions. The present review includes recent information covering different aspects carotenoid production sp. fermentation. This focuses on fermentation strategies, describing various economic raw materials as sources carbon and nitrogen, capacity tolerance heavy metals, effect light, pH, salts accumulation carotenoids. Genetic modification strategies used obtain strains with increased described. Furthermore, using magnetic nanoparticles system, which could be a factor increases pigment production, is first time. potential source high-value applications cosmetics, pharmaceutical, industries.

Molecular Regulation of Carotenoid Accumulation Enhanced by Oxidative Stress in the Food Industrial Strain Blakeslea trispora

Foods, Journal Year: 2025, Volume and Issue: 14(9), P. 1452 - 1452

Published: April 23, 2025

Blakeslea trispora is a key industrial strain for carotenoid production due to its rapid growth, ease of cultivation, and high yield. This study examined the effects oxidative stress induced by rose bengal (RB) hydrogen peroxide (H2O2) on accumulation, achieving maximum yields 459.38 ± 77.15 μg/g dry cell weight (DCW) at 0.4 g/L RB 294.38 14.16 DCW 0.6% H2O2. These results demonstrate that promotes accumulation in B. trispora. To investigate underlying molecular mechanisms, transcriptional levels genes were analyzed under optimal conditions. In carotenogenic pathway, only HMGR showed upregulation, while ACC, linked fatty acid biosynthesis, remained unchanged. Within mitogen-activated protein kinase (MAPK) FUS3 transcription increased both conditions, MPK1 H2O2 stress, HOG1 exhibited no significant changes. Among heat shock proteins (HSPs), HSP70 elevated other HSP findings suggest enhances through distinct regulatory pathways. provides valuable insights into stress-adaptive mechanisms offers strategies optimize fungi.

Production of Carotenoids by Microorganisms

Fermentation, Journal Year: 2024, Volume and Issue: 10(10), P. 502 - 502

Published: Sept. 30, 2024

Carotenoids are one of the most studied groups biologically active compounds. They have antioxidant, anti-inflammatory, anti-cancer, and coloring properties particularly interesting for pharmaceutical, nutraceutical, food, feed, cosmetic, textile industries. Rapidly growing consumer demand natural products has led to a significant increase in research development opportunities their production from sources. Among sources carotenoids origin, various microorganisms greater interest. This mini-review briefly summarizes information published mainly during last decade about carotenoid-producing microorganisms, physiological importance microbial cells, possibilities improve biosynthesis. review also describes some new approaches/directions make biotechnological more efficient.

Integration of plant and microbial oil processing at oilcane biorefineries for more sustainable biofuel production

GCB Bioenergy, Journal Year: 2024, Volume and Issue: 16(11)

Published: Oct. 25, 2024

Abstract Oilcane—an oil‐accumulating crop engineered from sugarcane—and microbial oil have the potential to improve renewable production and help meet expected demand for bioderived oleochemicals fuels. To assess synergies of processing both plant oils, economic environmental implications integrating at oilcane sugarcane biorefineries were characterized. Due decreased yields that lead higher simulated feedstock prices lower biorefinery capacities, current prototypes result in costs carbon intensities than sugarcane. inform development, we calculated required biomass (as a function content) achieve financial parity with At 10 dw% oil, can sustain up 30% less yield still be more profitable all scenarios. Assuming continued improvements cane juice, achieving this target results minimum biodiesel selling price 1.34 [0.90, 1.85] USD∙L −1 (presented as median [5th, 95th] percentiles), intensity 0.51 [0.47, 0.55] kg CO 2 e L , total 2140 [1870, 2410] ha year .
