Physiological and biochemical studies during fruit ripening in litchi (Litchi chinensis Sonn.)

Research to determine the ripening time of the fruit is the scientific basis for better harvesting and preservation. Physiological and biochemical methods were used to analyze the changes of some indicators according to the growth and development of banana fruit grown in Thanh Liet commune, Thanh Tri district, Hanoi from the time of its formation until the fruit ripening. The results showed that the banana reached the maximum size at 16 weeks old, at this time the peel was yellow due to the decrease in chlorophyll and increased carotenoid content. The content of vitamin C and total organic acid content reached their maximum when the fruit at 12 weeks old, then decreased gradually. Starch content increased to 14 weeks old, then decreased. Reduced sugar content increased gradually to 16 weeks old and then decreased. Protein content decreased gradually from fruit formation until fruit ripening, lipid content increased gradually to 15 weeks old, then decreased. Through the research process, we have determined that the physiological ripe time of banana fruit was 16 weeks old, this is the time when the fruit stops growing and accumulates many nutrients.

The genus Dunaliella is widely studied microalgae for its tolerance to extreme conditions, physiological aspects and many biotechnological applications, such as beta-carotene, protein, lipids and many other bioactive compounds. Physiological and biochemical studies are essential to fully explore the properties and possibilities of new isolates of Dunaliella.The aim of this study was to describe cellular morphology, growth rate and protein content of three Dunaliella strains, isolated from salty lakes in Mongolia. The cellular morphology, growth rates, protein contents were studied using microscopic analyses, Neubauer’s chamber, and micro kjeldahl method.Results showed that growths of all three Dunaliella cultures were progressed through lag phase at 3rd day. The growth of Dunaliella D-1 reached its peak on day 6, while Dunaliella D-6 and D-7 reached their stationary phase on day 7. Furthermore, the protein contents of dry biomass in Dunaliella D-1, D-6 and D-7 cultures were 62.2%, 36.1% and 38.15%, respectively. The highest protein content was found in Dunaliella D-1 culture, hence this culture could be used as protein rich supplement in further study.
