The percentage of spherical colonies from the trichomes of Nostoc sphaeroides reached 62-73% after 16 days with 50 and 250 μM P, but only 10-15% at 0.5 and 5 μM P. During colony formation from microcolonies to macrocolonies, the growth rates were 95, 206 and 244% higher, respectively at 5, 50 and 250 μM P than that at 0.5 μM P. The light-saturated photosynthetic rate, maximum electron transport rate and light-limited photosynthetic efficiency at 0.5 μM P decreased, respectively, by 45, 51 and 32% than those at 250 μM P. These indicated that the colony development, growth and photosynthetic capacities were restricted at low P level, suggesting that P might be an important factor limiting the productivity and distribution of N. sphaeroides in the field.

Pharmaceutically valuable products from microalgae and its industrial commercialization today is still in its infancy and can be seen as a gateway to a multibillion dollar industry. Microalgae generally grow autotrophically and are ubiquitous in nature. They represent a major untapped resource of genetic potential for valuable bioactive agents and fine biochemical. This proven ability of microalgae to produce these compounds places these microorganisms in the biotechnological spotlight for applications and commercialization as in the pharmaceutical industry. The production of microalgal metabolites, which stimulate defense mechanisms in the human body, has spurred intense study of the application of microalgal biomass and products thereof in various food preparations, pharmacological and medical products. There is, therefore, a huge scope for further study of the identified algal compounds and their activities in the treatment and prevention of various diseases, in addition to an ongoing search for other, as yet undetected, metabolites.

“…sphaeroides colonies were collected from the paddy fields of Zouma Town in December 2010, November 2011, and May 2012. Trichomes of N. sphaeroides for further cultivation were obtained from samples collected in December 2010 and November 2011, according to the method described by Deng et al (2008a) with modifications. Cultures derived from the sample collected in 2011 were designated as the short-term indoor cultivation group, while those derived from the sample collected in 2010 was designated as the long-term indoor cultivation group.…”

The influence of soil and water physicochemical properties on the distribution of Nostoc sphaeroides (Cyanophyceae) in paddy fields and biochemical comparison with indoor cultured biomass

et al. 2013

A survey on the distribution of Nostoc sphaeroides, an edible cyanobacterium, growing in mountain paddy fields of Zouma Town in China was carried out in May 2012. The physical and chemical properties of paddy field soil and water were analyzed. We found that in a paddy field in which N. sphaeroides historically did not grow when the water was acidic (pH 6.30) and showed the lowest conductivity, and the soil contained the lowest content of total phosphorus (TP) and available phosphorus (AP) compared to other fields where N. sphaeroides did grow. The nitrogen (N) contents in both water and soil samples were sufficient compared with the high N. sphaeroides yield paddy fields. These results suggest that an acidic water environment, as well as low TP and especially low AP, was the main limiting factors for the distribution of N. sphaeroides. In addition, comparison of the biochemical composition of field-harvested, short-term-cultivated, and longterm-cultivated N. sphaeroides showed that the contents of photosynthetic pigments (chlorophyll a and carotenoids) and soluble protein including phycobiliproteins increased gradually from wild habitat to long-term indoor cultivation N. sphaeroides, while both total and soluble carbohydrates showed a decreasing trend during indoor cultivation.
