Karakteristik Kimiawi dan Potensi Pemanfaatan Dunaliella salina dan Nannochloropsis
Abstract: The objective of
this research was to know the chemical characteristics and the potential
utilization of D.salina and Nannochloropsis sp. The research has been conducted
from December 2010 until April 2012 in Technology Of Fishery Product
Laboratory, Aquaculture Laboratory, Bioprocess Laboratory University of
Sriwijaya and Integrated Laboratory Bogor Agricultural University. The
parameters observed were biomass dry weight, proximate (moisture content, ash
content, protein content, fat content,
and total carbohydrate content), carotenoid, and amino acids.
Proximate composition of Nannochloropsis sp. obtained in this research
were 58.00% ash content, moisture content 12.39%, protein content 16.17%, fat
content 0.30%, total carbohydrate content 19.08%, total carotenoids 0.27 ppm,
and essential amino acids (histidine, threonine, arginine , methionine,
phenylalanine, valine, isoleucine, and leucine) and non-essential amino acids
(aspartic acid, glutamic acid, serine, glycine, alanine, and tyrosine). As for
the sample D.salina were the ash content 58.29%, water content 15.58%, protein
content 17.08%, fat content 0.003%, total carbohydrate content 15.07%, total
carotenoids 0.19 ppm, and essential amino acids (histidine , threonine,
arginine, methionine, phenylalanine, valine, isoleucine, leucine, and lysine)
and non-essential amino acids (aspartic acid, glutamic acid, serine, glycine,
alanine, and tyrosine). From the results of data analysis and chemical
characteristics of dry weight D.salina and Nannochloropsis sp. obtained in this
study, biomass produced this research has the chemical characteristics of lower
quality than the quality requirements of microalgae as an industrial raw
material of food, feed, biodiesel and bioethanol.
