Growing concerns over food shortages and climate-related environmental issues have increased interest in technologies that recycle renewable resources add value to byproducts. Here, we report microbial upcycling of agricultural cabbage waste (ACW) into phytoene, a novel dietary carotenoid through rational metabolic engineering. To make the base strain, ability produce phytoene was initially tested various E. coli strains harboring crtB crtE genes are essential for synthesis. Next, mevalonate biosynthetic pathway gene cluster introduced further increase carbon flux toward production. Finally, poly(3-hydroxybutyrate) [P3HB] biosynthesis phytoene-producing strain storage capacity enhance photostability phytoene. The final engineered PHY4 produced 9.51 mg/L (5.6 mg/g DCW) with productivity 0.4 mg/L/h from 1% ACW hydrolysates, resulting approximately 22.1-fold titer compared PHY1 (0.43 ± 0.06 mg/L) 10 g/L glucose. Moreover, exhibited three-fold improvement strategies reported here will be useful high-valued natural products.

Coffee cherry waste, a byproduct of coffee production, presents significant environmental challenges due to its large volume—approximately 20 million tons annually. The disposal this which includes pulp and mucilage, often leads pollution land water systems, contributing degradation. Additionally, the high acidity organic content waste complicate management, making it crucial find sustainable solutions for valorization reuse in order mitigate these ecological impacts. purpose study is investigate efficiency selectivity various acid catalysts hydrothermal waste. procedures were conducted using liquid hot (LHW) treatment one hour with 1:20 biomass/catalyst ratio 1 mm biomass particle size at 180 °C 500 mL batch reactors modifying 10 different acids 0.02 M. Concentrations valorized products (HMF, furfural, levulinic acid, formic sugars) measured HPLC-IR. Among tested, adipic demonstrated highest efficiency, total yield 53.667%, showing towards (19.663%) (11.291%). In contrast, butyric was least efficient catalyst, yielding 17.395% minimal other compounds. Chloroacetic benzoic notable their sugars. Other catalysts, such as anthranilic propanoic succinic displayed moderate selectivity, balanced yields across These findings highlight importance catalyst selection optimizing process desired product outcomes.
