In this study, Meyerozyma caribbica, an indigenously isolated oleaginous yeast, produced in media containing glucose a bioemulsifier that was partially characterized as a proteoglycan based on preliminary analysis. Optimization of carbon:nitrogen (C:N) ratio revealed 30:1 as the suitable ratio for enhanced production. Apart from higher emulsification activity (E24: 70-80%), this molecule showed strong emulsion stability over a wide range of pH (2.0-9.0), salinity (0.05%-10%, w/v) and temperature (- 80 °C to + 50 °C). The current study emphasizes on the determination of critical media parameters for improved and stable bioemulsifier production coupled with partial characterization and identification of the molecule. Thus, a proteoglycan-based bioemulsifier with such a stable emulsifying property can serve as a versatile and potential component in food, cosmetics and pharmaceutical formulations.

从油质酵母生产，部分纯化和鉴定蛋白聚糖生物乳化剂。

在这项研究中，Carybica Meyerozyma caribbica是一种原产地分离的油质酵母，在含有葡萄糖的培养基中产生了一种生物乳化剂，根据初步分析，该乳化剂的部分特征是蛋白聚糖。碳：氮（C：N）比的优化表明30：1是提高产量的合适比例。除了较高的乳化活性（E24：70-80％）外，该分子在广泛的pH值（2.0-9.0），盐度（0.05％-10％，w / v）和温度（-80° C至+ 50°C）。当前的研究着重于确定关键介质参数，以改善和稳定生产生物乳化剂，同时对分子进行部分表征和鉴定。从而，
