Article Abstract

This study explored the impact of sodium acetate (Na-acetate) impact on lipid, carotenoid, and β-carotene production by the newly isolated strain . Batch and fed-batch bioreactor cultures were employed to optimize growth conditions and product yields. fed with Na-acetate in the yeast medium was evaluated in the batch bioreactor culture. The following merits were accomplished for the cell dry weight (5.02 gL), lipid content (65.73%), carotenoid (40.33 µgg) and β-carotene (17.63 µgg) consistently. The fed-batch reactor cultivation using yeast extract supplemented with Na-acetate yielded superior lipid content (68.58%), cell dry weight (5.92 gL), carotenoid (48.36 µgg), and β-carotene production (21.38 µgg) compared to batch cultivation. The fatty acid methyl esters (FAMEs) are produced from the lipids suitable for biodiesel production. These findings highlight the potential of as a promising organism for sustainable biofuel and high-value compound production. Further optimization of culture conditions and downstream processing could enhance the commercial viability of this approach.

Refractory cytomegalovirus (CMV) infection is a severe complication following umbilical cord blood transplantation (UCBT). Antiviral agents, the standard first-line therapy, are limited by toxicity and resistance without robust T-cell immunity. We evaluated third-party donor (TPD)-derived CMV-specific T cells (CMVSTs) as a treatment option.

Spirulina is considered a superfood due to its chlorophylls. Two new methods for the determination of chlorophylls and β-carotene were developed here, one based on in-tube solid-phase microextraction (IT-SPME) coupled online to nanoliquid chromatography (nanoLC) with diode array detection (DAD), and the other on ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS). A protocol to extract the pigments from spirulina was proposed using ethanol (1.

Davies Livestock Research Centre, School of Animal and Veterinary Sciences, The University of Adelaide, Roseworthy, South Australia, Australia.

As sheep production standards progress, and animals are bred for high production in terms of the number and weight of lambs weaned per ewe, research has identified a difference in the physiology of single lambs compared to multiple born lambs. The current study aimed to report the baseline amino acid (AA) profiles and blood gas concentrations in newborn, Merino single and twin lambs. From 120 days of gestation, 50 single-bearing and 50 twin-bearing, naturally mated Merino ewes were monitored for signs of approaching parturition.

The pathogenic soilborne and postharvest fungus , as newly reported pathogen in Serbia, caused significant disease symptoms on carrot roots and seedlings in inoculation assays. In October 2023, machine-washed and cold-stored carrot roots showed symptoms of black rot of patches and abundant sporulation. The influence of the postharvest treatment of machine washing was confirmed by additional sampling at the production site.

Shenyang Agricultural University, College of Plant Protection, Nematology Institute of Northern China, Shenyang, China;

Root-knot nematodes (Meloidogyne spp.) cause catastrophic yield losses in global agriculture. This study identified itaconic acid (IA), through comparative metabolomic analysis (the study of small molecules in biological systems), as a key virulence-related metabolite produced by the fungus Trichoderma citrinoviride Snef1910.
