Simplified Method for the Cultivation of Spirulina for Domestic use

Spirulina is a blue-green algae. There are three predominant species in India namely Spirulina platensis, Spirulina fusiformis and Spirulina maxima. All of them are profusely enriched with nutrients. As a consequence, Spirulina formulations are made available in the market for use. Unique attributes of Spirulina are autotrophic and alkallophyletic and hence the energy requirements to maintain its culture at home are almost nullified. The sunlight that we obtain at our homes is more than adequate for its growth and replication. Mineral replenishment only needs to be supplemented. Yet, another important ingredient in the culture medium is pH. Spirulina prefers to grow in extreme alkaline medium under sunlight that restrains from most of the facultative bacteria and fungi which otherwise contaminate the culture medium. Therefore, little sophistication is required for its maintenance at domestic premises. The medium composition tried in our lab led to the profuse growth of the culture as indicated through the intensity of the green colour in the wider plastic tubs and obtained biomass was processed for the preparation of dried flakes. Methods: A screening test for mild cognitive impairment: Montreal Cognitive Assessment (MoCA test), measurement of body composition by an inner scan monitor, and stress level tests were performed by measuring ？±-amylase levels in the saliva from the sublingual gland. For statistical evaluation of scores before and after each cognitive test intervention, t tests were used. To test for relationships between the score of cognitive test and measured value of body composition and ？± - amylase levels, Pearson a？？s correlation coefficient was used. Results: Significant improvements in cognitive function were detected after each intervention, with the strongest correlating variable with the cognitive function and body composition comparisons being blood vessel age. Furthermore, there was a negative correlation between stress and cognitive function, with those patients with high stress levels having reduced cognitive function. Conclusions: Interventions that combine group-games and brain training are effective in preventing dementia. Negative correlations were detected between cognitive function and vascular age, and stress levels. Therefore, in order to maintain the cognitive function, it is necessary to improve the dietary life as a means of improving vascular age and perform activities to provide stress relief
