The Influence of the Macroalgae Liquid Extracts on the Pigments and Fatty Acids Profile of the Marine Microalga, Picochlorum maculatum (PSDK01)
2022
Overview
The present study was aimed to evaluate the effect of macroalgal liquid extract (MLE) on the growth, biomass, pigments and proximate composition in the
Picochlorum maculatum
cells. The water extracts of the seaweeds;
Padina gymnosphora, Halimeda macroloba, Caulerpa serrulata, Ulva intestinalis,
and
Halimeda opuntia
of the Mandapam (Southeast coast of India) were assessed for their growth enhancing property in microalga. Further, during the present experiments, an attempt was made for the formulation of an eco-friendly and low-cost, new microalgal – culture medium with the macroalgal liquids along with the minimum quantity of chemicals and commercial fertilizers And the present artificial culture media composition included 30 different combinations (except control) of chemicals (sodium nitrate, sodium ortho phosphate) and commercial fertilizers (urea, super phosphate, ammonium sulphate) along with five macroalgal liquid extracts. The experimental results suggest that the
P. maculatum
can be successfully grown under the newly formulated MLE-medium along as compared to that of expensive whole medium. The growth (0.12 abs), biomass (2.05 g L
−1
), chlorophyll ‘a’ (2.05 µg/ml), chlorophyll ‘b’ (1.55 µg/ml), total carotenoids (141.98 µg/ml), total fatty acids (76.82%), and total amino acids (92.56%) were found to be comparatively higher in
Ulva intestinalis
+ Ammonium Sulphate (UI + AS) combined medium than through the whole medium (control) cultured
P. maculatum
cells. This study clearly underlines the prospect of using MLE as an alternative nutrients supplier to stimulate the growth of microalga that would be an important development in aquaculture feed industry.
