“…Hasil penelitian Gordillo et al (2002) menunjukkan bahwa laju penyerapan fosfat dan nirat sesuai dan memiliki korelasi positif dengan peningkatan laju pertumbuhan. Menurut Buschmann et al (2004); Martines and Rico (2004), pertumbuhan dan biomassa dapat tercapai dengan baik bila rumput laut tercukupi oleh kedua unsur tersebut. Ketersedian fosfat dan nitrat di perairan seringkali menjadi faktor pembatas (Buschmann et al, 2004;Martines and Rico, 2004).…”

Ketersedian fosfat dan nitrat di perairan seringkali menjadi faktor pembatas (Buschmann et al, 2004;Martines and Rico, 2004). Tidak terdeteksinya kandungan fosfat air di area penelitian tidak menyebabkan fosfat sebagai faktor pembatas pertumbuhan karena fosfat diserap dari substrat tambak.…”

“…Nitrogen dapat meningkatkan pertumbuhan dan produksi budidaya rumput laut. Hasil penelitian Buschmann et al (2004) menunjukkan bahwa beberapa alga merah, seperti Gracilaria tumbuh lebih baik pada kondisi ammonium yang tinggi, sedangkan pada jenis lain, seperti Chondrus crispus dan Soliera chordalis, terlihat lebih baik ketika dilakukan penambahan nitrat, Namun dalam hal penyerapan nitrat, beberapa jenis algae memiliki perbedaan dalam menyerap unsur N, dimana ada jenis alga yang cenderung lebih dahulu menggunakan nitrat dan adapula yang lebih dahulu menggunakan ammonium (Roymont, 1980dalam Patadjai, 2007.…”

“…This basic knowledge includes aspects such as: the ultrastructure of the spores, phenological studies and population dynamics (Avila et al, 1999a), recruitment in natural populations , vegetative propagation in tanks and in the sea (Hernández-González et al, 2007;Romo et al, 2006;Correa et al, 1999;Westermeier et al, 2012), management (Avila et al,1999b;Westermeier et al, 2012), and methods of cultivation and repopulation (Avila et al, 1999a;Buschmann et al, 2001;Avila et al, 2003;Buschmann et al, 2004;Romo et al, 2006;Mansilla et al, 2008;Westermeier et al, 2012). Reproductive biological records indicate that this species exhibits seasonality in its sexual reproduction (Zamorano & Westermeier, 1996) and alternation in the dominance of reproductive stages, similar to that described for other species of Gigartinales (Kim, 1976).…”

This paper is a compilation of data from investigations made with marine benthic algae from the Magellan Region that have biotechnological utilization in human consumption or medicine or as a source of phycolloids or food supplements or animal feed. The most important Rhodophyta species are: Ahnfeltia plicata (Hudson) E.M. Fries for agarose production, Gigartina skottsbergii Setchell & N.L.Gardner for carrageenan production, and Callophyllis variegata (Bory de Saint-Vincent) Kützing for human consumption. The most important Heterokontophyta species are: Macrocystis pyrifera (L.) C. Agardh, and Durvillaea antarctica (Chamisso) Hariot for human consumption, alginate production, and as biofertilizer for agricultural crops. M. pyrifera is also used as a food supplement for salmon, chickens, quails, sheep and bovines and for biofuel production.

“…It is a very fast-growing algae and is known to double its biomass in every 15 days.The carrageenan secreted by these algae is of different types and differ in composition and conformation, resulting in a wide range of rheological and functional properties. Carrageenans are used in a variety of commercial applications as gelling, thickening, and stabilizing agents, especially in food products such as frozen desserts, chocolate milk, cottage cheese, whipped cream, instant products, yogurt, jellies, pet foods, and sauces [1][2][3][4][5]. They are also used in pharmaceutical formulations, cosmetics, and industrial applications such asmining.…”

Expression of Genetical Diversity of Kappaphycus Sp. Among Other Algae Using Bioinformatics Tools

Kappaphycus sp. belongs to the family of red algae and is one of the most important commercial sources of carrageenans. As the 18S gene of the whole DNA codes for the conserved segment in the eukaryotic organisms that speaks about the personal identity of the organisms, these sequences have been used to describe the genetic relation of Kappaphycus sp. with that of other algae. The Clustal X and Tree View analysis of these sequences has shown the diversity and convergence in the genetic identity matrix created for the selected reference sequences and the Kappaphycus sp. sequences used. This has enabled us to design the genetic identity matrix thus enabling the explanation of the relation that the algae Kappaphycus sp. demonstrated with other algae.
