摘要

海洋酵母菌在工业、医疗和环境领域有着广泛的应用。然而，与陆生酵母菌和丝状真菌相比，它们很少受到关注。本研究利用内部转录间隔和核大亚基 rDNA 对 11 种海洋酵母菌进行了系统发育分析，并研究了它们的生物活性，如抗氧化、抗菌和抑制酪氨酸酶活性。经鉴定，这11种海洋酵母属于7个物种，包括Geotrichum candidum、Metschnikowia bicuspidata、Papiliotrema fonsecae、Rhodotorula mucilaginosa、Vishniacozyma carnescens、Yamadazyma olivae和Yarrowia lipolytica，其中3株候选为Aureobasidium属、Rhodotorula属和Vishniacozyma属的新物种。大多数提取物具有抗氧化活性，而 7 株菌株对枯草杆菌具有抗菌活性。11 个分离株中只有 Aureobasidium sp. US-Sd3 对酪氨酸酶有抑制作用。Metschnikowia bicuspidata BP-Up1 和 Yamadazyma olivae K2-6 具有显著的自由基清除活性，这是以前从未报道过的。此外，Aureobasidium sp. US-Sd3 的抗菌和抑制酪氨酸酶活性最高。这些结果表明，海洋酵母具有作为生物活性化合物来源的潜力，可改善工业应用。

Characterization and Biological Activities of Yeasts Isolated from Marine Environments

Marine yeasts have versatile applications in the industrial, medical, and environmental fields. However, they have received little attention compared to terrestrial yeasts and filamentous fungi. In this study, a phylogenetic analysis of 11 marine-derived yeasts was conducted using internal transcribed spacers and nuclear large subunit rDNA, and their bioactivities, such as antioxidant, antibacterial, and tyrosinase inhibition activities, were investigated. The 11 marine-derived yeasts were identified to belong to seven species including Geotrichum candidum, Metschnikowia bicuspidata, Papiliotrema fonsecae, Rhodotorula mucilaginosa, Vishniacozyma carnescens, Yamadazyma olivae, and Yarrowia lipolytica, and three strains of these were candidates for new species of the genera Aureobasidium, Rhodotorula, and Vishniacozyma. Most extracts showed antioxidant activity, whereas seven strains exhibited antibacterial activities against Bacillus subtilis. Only Aureobasidium sp. US-Sd3 among the 11 isolates showed tyrosinase inhibition. Metschnikowia bicuspidata BP-Up1 and Yamadazyma olivae K2-6 showed notable radical-scavenging activity, which has not been previously reported. Moreover, Aureobasidium sp. US-Sd3 exhibited the highest antibacterial and tyrosinase inhibitory activities. These results demonstrate the potential of marine-derived yeasts as a source of bioactive compounds for improving industrial applications.

期刊介绍： Microbiology Research is an international, online-only, open access peer-reviewed journal which publishes original research, review articles, editorials, perspectives, case reports and brief reports to benefit researchers, microbiologists, physicians, veterinarians. Microbiology Research publishes ‘Clinic’ and ‘Research’ papers divided into two different skill and proficiency levels: ‘Junior’ and ‘Professional’. The aim of this four quadrant grid is to encourage younger researchers, physicians and veterinarians to submit their results even if their studies encompass just a limited set of observations or rely on basic statistical approach, yet upholding the customary sound approach of every scientific article.
