International Islamic University Malaysia-IIUM.Kappaphycus alvarezii is one of the main seaweeds cultivated inIndonesia. Its use as a raw material for the kappa-carrageenan industry has increased itscultivation activities. However, standard cultivation protocol for Kappaphycus alvareziihas yet to be well-documented, particularly on strain selection for kappa-carrageenanproduction. There are various strains of Kappaphycus alvarezii grown in Indonesia,specifically in Serang, Banten such as green, red, and yellowish green strains. In thisstudy, growth rate, carrageenan yield, and gel strength from different strains ofKappaphycus alvarezii were investigated. It was observed that the specific growth rate ofgreen type (4.14% /day) differed significantly from the other two types (red; 3.41% /dayand yellowish green; 3.47% /day). The red type had the highest yield of carrageenan(45.16%) followed by yellowish green (36.66%) and green strain (33.67%). Gel strengthwas not significantly affected by the strain variations where the observed values foryellowish green, green, and red strain were 344.46, 316.91 and 313.10 g/cm2,respectively. Green Kappaphycus alvarezii had the highest biomass (0.27 g/cm/d) andcarrageenan productivity (0.012 g/cm/d). It can be concluded that the green strain of Kappaphycus alvarezii is the most suitable for cultivation in Serang, particularly for thekappa-carrageenan industry.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Carrageenan yield,Gel strength,Kappaphycus alvarezii,Productivity,Specific growth rate[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.31436/iiumej.v20i2.1062[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
