Hai loài rong, U. reticulata và U. lactuca, có chứa nhiều loại acid amin và khoáng vi lượng, các chất này có lợi cho sức khỏe người sử dụng. Theo nghiên cứu Myonglae (2010), các dẫn xuất polysaccharid từ rong Ulva có ứng dụng rất lớn trong sản xuất thực phẩm chức năng và chế phẩm trong y học. Do những công dụng của rong Ulva, nghiên cứu kỹ thuật nuôi rong Ulva bằng công nghệ sạch để tạo ra nguyên liệu cho các ứng dụng rất có ý nghĩa thực tiễn. | Nghiên cứu kỹ thuật nuôi dinh dưỡng rong Ulva papenfussii TAP CHI SINH HOC 2019, 41(1): 91–99 DOI: A NUTRIENT METHOD FOR CUTIVATION OF MACROALGAE Ulva papenfussii Vo Thanh Trung1,*, Tran Van Huynh1, Tran Mai Duc1, Pham Duc Thinh1, Pham Trung San1, Nguyen Thanh Hang2 1 Nha Trang Institute of Technology Reasearch and Aplication, VAST, Vietnam 2 School of Biotechnology and Food Technology, Hanoi University of Science and Technology, Vietnam Received 26 May 2018, accepted 7 March 2019 ABSTRACT Macroalgae species of the genus Ulva are widely distributed in the wild, many species of this genus has been used as food as an attractive material for the study of materials, fuels, food etc In this paper, we are focusing on nutrient method for cultivation of Ulva papenfussii and A nutrient source for cultivation of U. papenfussii was also investigated with the perspective of utilizing the produced biomass for feed. U. papenfussii is fragmented into 1 × 1 cm size, then it keep in Ulva extract of g/l concentrate for 7 days. Then continue to keep fragments in the following conditions: 20 ml/l of PES medium, 700 μmol photon/m2/s of light, 25oC of temperature, 3% of salinity, 28 days of time. Under this condition the productivity U. papenfussii was g/l of weight and its growth rate was – day. Nutritional cultivation is successful for U. papenfussii speceies, which is of great importance to study the potential of producing seaweed varieties like blades for commercial application of seaweed species.
