Lipases produced by a newly isolated Sporidiobolus pararoseus strain have potential catalytic ability for esterification reactions. After production, the enzymatic extracts (conventional crude and precipitated, 'CC' and 'CP', and industrial crude and precipitated, 'IC' e 'IP') were partially characterized. The enzymes presented, in general, higher specificity for short chain alcohols and fatty acids. The precipitated extract showed a good thermal stability, higher than that for crude enzymatic extracts. The 'CC' and 'CP' enzymes presented high activities after exposure to pH 6.5 and 40 °C. On the other hand, the 'IC' and 'IP' extracts kept their activities in a wide range of pH memory but presented preference for higher reaction temperatures. Preliminary studies of application of the crude lipase extract in the enzymatic production of geranyl propionate using geraniol and propionic acid as substrates in solvent-free system led to a reaction conversion of 42 ± 1.5%.

Rheumatoid arthritis (RA) is an autoimmune-mediated disease with the highest disability rate. Sporidiobolus pararoseus polysaccharides (SPP) have been demonstrated to have anti-rheumatoid and microbiota-modulatory effects; however, the underlying mechanisms remain unclear. This study employed collagen-induced arthritis (CIA) mice to explore the metabolic and genetic pathways.

Article Synopsis
- This study investigates how adding passion fruit peel pectin and red yeast cell walls to the diet of Nile tilapia affects their growth, immunity, and gut health over an 8-week period.
- The results showed that the combined supplementation led to significant improvements in growth metrics and immune responses compared to control and individual supplement diets.
- Analysis also revealed enhanced gut health, with better intestinal morphology and increased diversity of beneficial gut bacteria, suggesting these supplements could be beneficial alternatives in aquaculture practices.

Soy sauce is a traditional condiment that undergoes microbial fermentation of various ingredients to achieve its desired color, scent, and flavor. Sporidiobolus pararoseus, which is a type of Rhodocerevisiae, shows promising potential as a source of lipids, carotenoids, and enzymes that can enrich the taste and color of soy sauce. However, there is currently a lack of systematic and comprehensive studies on the functions and mechanisms of action of S.

Rheumatoid arthritis (RA) is becoming a prevalent autoimmune disease affecting people worldwide, necessitating the exploration of novel therapeutic approaches due to the associated adverse effects of conventional therapeutic drugs. Sporidiobolus pararoseus polysaccharide (SPP) has been shown to exhibit significant immune stimulation and antioxidant activities. In this study, we constructed a mouse model of type II collagen-induced arthritis (CIA) to investigate the effects and potential mechanisms of SPP intervention on RA.
