How Close Are We to the Production of Milk in Alternative Systems? The Fat Perspective

Foods, Journal Year: 2025, Volume and Issue: 14(5), P. 809 - 809

Published: Feb. 26, 2025

The growing demand for sustainable food systems has led to significant advancements in developing alternatives animal-derived products. Dairy products are an important dietary source of proteins and fats; however, their production raises environmental concerns, including greenhouse gas emissions, extensive land water usage, biodiversity loss. Therefore, there is a need develop sustainable, scalable solutions that will enable the quality replacements animal-based foods with reduced impacts. Recognizing replacing from single currently not feasible; high-quality sources ingredients can be combined mimic holistic product. In recent years, plant-based dairy have gained traction; inability replicate sensorial experience real milk-attributed largely unique composition structure milk fat-remains key limitation. Cow's fat distinctive characteristics, complex fatty acid profile, which rich short- medium-chain saturated acids specific positional distribution. These characteristics cow's play role delivering aroma, texture, mouthfeel Recent efforts focused on leveraging precision fermentation cellular agriculture these properties. This review explores lipid ruminant milk, biosynthesis fats, challenges replicating features non-mammalian systems. Emphasis placed short-chain chain-termination mechanisms synthesis. By integrating insights diverse biological systems, we aim contribute deeper understanding processes related

Tropical lakes as a novel source of oleaginous yeasts with lipid profiles for biodiesel, oleochemical, and nutraceutical applications

World Journal of Microbiology and Biotechnology, Journal Year: 2025, Volume and Issue: 41(3)

Published: March 1, 2025

Abstract Oleaginous yeasts have emerged as promising microbial cell factories for lipid production, offering sustainable alternatives to traditional sources of biodiesel and nutraceuticals. In this study, the accumulation potential yeast strains isolated from two freshwater aquatic ecosystems in Cali, Colombia, was evaluated identify novel candidates biotechnological applications. A total 56 were tested their oleaginous nature using a gravimetric assay with glucose carbon source. Of assessed strains, 46.15% exceeded 20% yields relative dry biomass. Seven selected glycerol source, but only five further characterized profiles. Molecular identification revealed diverse species, including Aureobasidium sp., Papiliotrema rajashtanensis, Rhodotorula spp., Clavispora lusitaniae . The demonstrated unique profiles, high proportions monounsaturated polyunsaturated fatty acids, such oleic acid (C18:1) linoleic (C18:2). particular, sp. accumulated uncommon acids petroselinic under conditions induced by glycerol. This acid, which has double bond position 6,7 melting point 33 °C, highlights its an alternative margarine well precursor sophorolipids, estolide esters, soaps, plastics. exhibited very long-chain docosadienoic docosatrienoic profile. These findings underscore value lentic systems producers, paving way innovations biofuels, nutraceuticals, oleochemicals.

Impacts of conventional and industrial wastewaters-based media on biomass production, nutrient dynamics, and fatty acid profile in a thraustochytrid culture

Preparative Biochemistry & Biotechnology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 14

Published: April 4, 2025

The rising demand for polyunsaturated fatty acids, coupled with the decline of traditional fish-based sources, highlights Ulkenia visurgensis Lng2, a newly isolated thraustochytrid strain, as promising alternative sustainable acids production. Using Response Surface Methodology to optimize medium composition and culture conditions, biomass production was improved 11.64 g/L-120% higher than previous studies-with 35% consisting total lipids. Of 40% corresponded including 27% docosahexaenoic acid, 4% eicosapentaenoic 7% arachidonic acid. Alternative media, such wastewaters from corn fish meal processing, were also evaluated. Biomass yields in wastewaters-based media (30% v/v) lower due limited nutrient availability, achieving between 2.96 g/L 2.28 g/L, strain showing mostly around 8% carbon nitrogen assimilation. Morphological changes, increased vegetative multinucleated cells, observed. Lipid content decreased wastewater-based cultures, yet PUFAs constituted 47% EPA nearly doubling, DHA remaining stable ARA content. These results shed light on how U. Lng2 adapts nutrient-limited environments offer valuable insights developing PUFA using industrial by-products media.
