Enhanced 2-Phenylethanol Production by Meyerozyma Strain YLG18

A unique Meyerozyma sp. strain YLG18 was isolated, capable of producing 2-phenylethanol via Ehrlich and Shikimate pathways. Response surface methodology optimization increased production to 2.55 g/L, a 104% improvement, and in situ product recovery further boosted it to 3.20 g/L. The research, led by Fengxue Xin of Nanjing Tech University, identified key genes like AroM and an aspartate aminotransferase involved in the synthesis pathways.

Use Cases

• Optimizing bioproduction conditions for 2-phenylethanol based on temperature, glucose, and L-phenylalanine concentrations.
• Comparing gene expression levels between the Shikimate and Ehrlich metabolic pathways.
• Evaluating in situ product recovery methods using fatty acid methyl ester as an extractant.
• Identifying novel microbial strains and enzymes for industrial biosynthesis.

Strengths

• Optimization led to a 104% increase in 2-PE production to 2.55 g/L.
• In situ product recovery achieved a final production level of 3.20 g/L.
• Specific genes (AroM, aspartate aminotransferase) were identified and their expression compared.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness is unverified as the last update date is unknown.
