Outdoor cultivation of Spirulina maxima. I. Winter
AbstractBiomass of photosyntethesizing microorganisms has a tremendous potential for both human and animal feeding due to their over 50% protein content on a dry matter basis. Cultures kept in laboratory require an artificial source of light for their satisfactory growth whereas the large scale production systems take advantage of solar light. Thus, these systems are also afected by environmental conditions such as ambiental temperature, culture temperature, relative humidity of air and rainfall.
The effect of these factors in winter season on production of Spirulina maxima biomass were evaluated. Also protein content as well as amino acids profile were determined. A biomass production graph plotted against
period of day (morning, afternoon and evening) indicated that the best production period was from 8:00 a.m. to 1:00 p.m. while a growth curve showed maximum yield of 8:08 g/square meter/day. Lack of rainfall and water losses due to evaporation required reposition of water equivalent to 72.14 mm of rain.
