The harvested algal biomass contained high nutritive compositions and was a suitable source for functional food ( % protein, % lipids and low heavy metal concentration). The obtained results indicated that the My An mineral water source is indeed a suitable water source for producing Spirulina platensis biomass as a functional food for human and animal feed. | Vietnam Journal of Science and Technology 55 (5) (2017) 548-556 DOI: EXPERIMENTAL CULTIVATION OF Spirulina platensis USING MY AN MINERAL WATER, THUA THIEN HUE PROVINCE Vu Thi Nguyet1, 2, *, Dang Dinh Kim1, 2, Nguyen Hong Chuyen1, Vu Thi Thanh Tam3, Tran Phuong Ha3, Pham Viet Cuong3, Ton That Huu Dat3, *, Hoang Phan Bich Ngoc3, Nguyen Thi Thu Thuy4 1 2 Institute of Environmental Technology, VAST, 18 Hoang Quoc Viet, Cau Giay, Ha Noi Graduate University of Science and Technology, 18 Hoang Quoc Viet, Cau Giay, Ha Noi 3 4 Mientrung Institute for Scientific Research, VAST, 321 Huynh Thuc Khang, Hue City Vietnam National University of Agriculture, Ngo Xuan Quang, Trau Quy, Gia Lam, Ha Noi * Email: tranvunguyet@ Received: 24 March 2017; Accepted for publication: 1 August 2017 ABSTRACT Spirulina platensis was experimentally cultivated by semi-continuous method at 20 m2 scale pilot for the effective use of the available bicarbonate and minerals in My An mineral water, Phu Vang district, Thua Thien Hue province in order to reduce production costs. Analysis results of My An water quality showed that this mineral water source was suitable to Spirulina platensis cultivation after removing H2S. The average yield of the alga reached 10 g dry biomass/. The harvested algal biomass contained high nutritive compositions and was a suitable source for functional food ( % protein, % lipids and low heavy metal concentration). The obtained results indicated that the My An mineral water source is indeed a suitable water source for producing Spirulina platensis biomass as a functional food for human and animal feed. Keywords: algal biomass, functional food, My An mineral water, semi-continuous cultivation, Spirulina platensis. 1. INTRODUCTION Spirulina platensis Geitl. (cyanobacterium) is a multicelular filamentous form, belonging to the Oscillatoriaceae, Cyanophyceae, Cyanophyta and is known as a rich-nutrient food source. Since
