The gene YALI0F01562g was identified as an important factor involved in erythritol catabolism of the unconventional yeast Yarrowia lipolytica. Its putative role was identified for the first time by comparative analysis of four Y. lipolytica strains: A-101.1.31, Wratislavia K1, MK1 and AMM. The presence of a mutation that seriously damaged the gene corresponded to inability of the strain Wratislavia K1 to utilize erythritol. RT-PCR analysis of the strain MK1 demonstrated a significant increase in YALI0F01562g expression during growth on erythritol. Further studies involving deletion and overexpression of the selected gene showed that it is indeed essential for efficient erythritol assimilation. The deletion strain Y. lipolytica AMM∆euf1 was almost unable to grow on erythritol as the sole carbon source. When the strain was applied in the process of erythritol production from glycerol, the amount of erythritol remained constant after reaching the maximal concentration. Analysis of the YALI0F01562g gene sequence revealed the presence of domains characteristic for transcription factors. Therefore we suggest naming the studied gene Erythritol Utilization Factor - EUF1.

Objectives: To evaluate the change in salivary pH using xylitol- and erythritol-containing lollipops and chewing gums, and assess the correlation between sugar substitutes and change in pH levels of saliva.
Materials And Methods: The present crossover study was conducted in 60 children between 3 and 9 years of age from a private school who had not received any meal for 2 hours prior to examination. There were three groups in this study: group I, control group (rinsing with tap water); group II, experimental group (with sugar substitute lollipops); and group III, experimental group (with sugar substitute chewing gums).

Terpenoids, abundant and structurally diverse secondary metabolites in plants, especially in conifer species, play crucial roles in the plant defense mechanism and plant growth and development. In , terpenoids' biosynthesis relies on both the mevalonate (MVA) pathway and the 2-methyl-D-erythritol-4-phosphate (MEP) pathway, with 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase (HDS) catalyzing the sixth step of the MEP pathway. In this study, we cloned and conducted bioinformatics analysis of the gene from .

Mutual acquisition of phase-stability and controllable phase-transition becomes a predominant criterion of phase-change materials for the practical long-term energy storage but seems contradictory always. Here a strategy combining coordination and hydrogen bonds hierarchically to create a supercooled liquid in a core-shell coordination structure is reported, addressing that demand successfully. This new material is composed of a Mn-methylurea complex (MM) core and the hierarchically bonded erythritols shell.

Erythritol is a beneficial sugar alcohol that can be used as a sugar substitute for diabetic patients. Erythritol is a bioproduct produced by microorganisms as a response to high osmotic pressure and stress in the growth medium. High concentrations of carbon source substrate can increase the osmotic pressure and provide more nutrient supply for yeast growth and metabolism.

In this study, maltotriosyl-erythritol (EG) was synthesized as a novel prebiotic candidate via transglycosylation using recombinant amylomaltase (AMase) from Thermus sp. Tapioca starch served as the glucosyl donor, and erythritol as the acceptor. High-performance liquid chromatography (HPLC) revealed an EG yield of 14.
