Spirulina, real aid to development
World population in 1960 was about 3 x 109; today it is 5 x 109; and in the year 2000 it is expected to be about 7 x 109. Yes, there is need for protein, vitamins, and minerals — more than can be provided by conventional means. As farmland will be at an ever-increasing premium, non-conventional food sources such as bacteria and yeasts which require organic substrates can be excluded. Photosynthetic aquatic biomass is the only practical resource awaiting general exploitation. Microalgae, with their rapid growth rate, are the most efficient producers of such biomass. And Spirulina (Arthrospira), by virtue of its high available protein and vitamin content (Clément et al., 1967), relative ease of exploitation (Becker & Venkataraman, 1982; Umesh & Seshagiri, 1984), and long history of human consumption (Furst, 1978), is the favored microalga.
