Enhanced co-production of extracellular biopolymers and intracellular lipids by Rhodotorula using lignocellulose hydrolysate and fish oil by-product urea.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundA key objective in microbial biorefinery technologies is to identify resilient microorganisms capable of simultaneously synthesizing diverse bioactive metabolites. Among these, Rhodotorula yeasts emerge as promising candidates for converting various waste streams and by-products into high-value chemicals. Their industrial potential stems from their ability to accumulate significant amounts of lipids and carotenoids while also secreting extracellular polymers such as exopolysaccharides, polyol esters of fatty acids, glycolipids, and enzymes-many of which remain to be fully characterized.
resultsAmong the five Rhodotorula strains tested, three exhibited substantial exopolysaccharide production. Notably, Rhodotorula graminis CCY 20-2-47 strain was identified, for the first time, to produce two distinct extracellular biopolymers-exopolysaccharides or polyol esters of fatty acids-depending on the growth conditions. It was observed enhanced production of exopolysaccharides up to 7.2 g L
conclusionsIn conclusion, Rhodotorula yeasts demonstrate significant potential for microbial biorefineries due to their ability to efficiently convert diverse waste substrates into valuable biomaterials, including lipids and extracellular biopolymers. This study provides new insights into a potential metabolic switch in extracellular polymer biosynthesis, driven by Mn
