transcriptome sequencing and characterization for Kappaphycus alvarezii
European Journal of Phycology, 2015Co-Authors: Zhen Zhang, Tong Pang, Litao Zhang, Jianguo LiuAbstract:The transcriptome of Kappaphycus alvarezii was profiled using high-throughput Solexa paired-end sequencing technology. A total of 61 million sequencing reads was generated by filtering the low-quality reads, and 28 701 unigenes with a mean length of 901 bp were obtained based on de novo assembly. In similarity alignments against the NCBI non-redundant protein sequence (NR) database, Swissprot database, Cluster of Orthologous Groups (COG) database, Gene ontology (GO) database, and Kyoto Encyclopedia of Genes and Genomes (KEGG) database, 11 996 (41.79%) unigenes were identified with significant hits (E-value < 10(-5)) against existing genes. Functional annotation with the KEGG pathway database identified 8975 unigenes and mapped to 125 pathways. Through functional enrichment analysis of the genes with a higher expression value than the average RPKM (reads per kilobase per million reads), we found that some important pathways were highly expressed. The substantial number of transcript sequences of K. alvarezii provides a valuable resource for potential gene identification and comparative genomic studies.

Copper (II) and Nickel (II) Sorption onto Seaweed (Kappaphycus alvarezii) Waste Biomass: Equilibrium and Mechanism Studies
2011Co-Authors: Oon Lee Kang, Suhaimi Md Yasir, Nazaruddin Ramli, Mamot Said, Musa Ahmad, Arbakariya B. AriffAbstract:Cu (II) and Ni (II) sorption were investigated using seaweed (Kappaphycus alvarezii) waste biomass. The metal sorption experiments were conducted at different pH values (pH 2-6) and initial metal concentrations (10-50 mg/L). The equilibrium sorption data were fitted to Langmuir and Freundlich isotherms and the isotherm parameters were evaluated at different initial metal concentrations. The metal sorption capacities were found to be pH dependent and increased with initial metal concentration. The maximum observed Cu (II) and Ni (II) sorption capacities (Q ) were 4.5872 and 12.3460 mg/g (according to the Langmuir isotherm). The metal max sorption mechanisms were determined to be ion exchange and complexation. In combination, Kappaphycus alvarezii waste biomass represents a cost-effective and efficient metal sorbent to remove metal ions.

Kappaphycus alvarezii waste biomass: A potential biosorbent for chromium ions removal
Journal of environmental sciences (China), 2011Co-Authors: Oon Lee Kang, Suhaimi Md Yasir, Nazaruddin Ramli, Mamot Said, Musa Ahmad, Arbakariya B. AriffAbstract:The Cr(III) sorption experiments onto Kappaphycus alvarezii waste biomass were conducted at different pH values (2-6) under the conditions of initial metal concentration of 10-50 mg/L and the chemical compositions of Cr-Cu and Cr-Cd. The Cr(III) sorption capacities were slightly dependent on pH, and the maximum sorption capacity was 0.86 mg/g at pH 3. The sorption capacities increased with increase in the initial metal concentration, whereas it was suppressed by the presence of Cu(II) and Cd(III) in the solution. The Cr(III) sorption equilibrium was evaluated using Langmuir, Freundlich and BET isotherms. The sorption mechanisms were characterised using scanning electron microscopy and Fourier transform infrared spectroscopy. The main mechanisms were ion exchange coupled with a complexation mechanism. Kappaphycus alvarezii waste biomass represents a potential for Cr(III) ion removal from aqueous solution.

Competitive metal sorption and desorption onto Kappaphycus alvarezii, seaweed waste biomass
2011Co-Authors: Oon Lee Kang, Suhaimi Md Yasir, Nazaruddin Ramli, Mamot Said, Musa Ahmad, Arbakariya B. AriffAbstract:Competitive metal sorption and desorption onto Kappaphycus alvarezii waste biomass were investigated. Metal sorption capacities were 0.82 mg Cr(III)/g, 0.73 mg Ni(II)/g, 0.67 mg Cd(II)/g, 0.65 mg Cu(II)/g and 0.64 mg Zn(II)/g in multi metal system. Whereas, desorption efficiencies were 66.08%, 71.50% and 80.44% using 0.1M HNO 3, 0.1M HCl and 0.1M H 2SO 4, respectively. The metal sorption sequence were Cr(III) > Ni(II) > Cd(II) > Cu(II) > Zn(II), while metal desorption sequence were Cd(II) > Zn(II) > Cu(II) > Ni(II) > Cr(III). Fourier transformed infrared spectroscopy (FTIR) technique was used to characterize the seaweed waste biomass. FTIR analysis shown that carbonyl (-C-O) and nitrile (-Câ‰iN) groups interact with the metal ions. The experiments result revealed that Kappaphycus alvarezii waste biomass represent an attractive candidate to remove multi metal ions.

Cage culture of Kappaphycus alvarezii var. tambalang (Gigartinales, Rhodophyceae)
Journal of Applied Phycology, 1992Co-Authors: Anicia Q. Hurtado-ponceAbstract:Kappaphycus alvarezii var.tambalang was cultured in a 3 × 3 m bamboo raft installed inside a 4 × 4 m floating net cage ofLates calcarifer (sea bass) broodstock at SEAFDEC Sub-station Igang, Guimaras, Philippines, from December 1989 to May 1990. Growth and production ofK. alvarezii var.tambalang was influenced by the culture months. The highest growth rate and production were recorded in January and May, respectively, while the lowest growth rate and production were observed in March. Average growth rate (wet weight) ranged from 3.72 to 7.17% day-1, while production ranged from 575.5 to 2377 g m-1 line-1. A total production of approximately 123 t (fresh) or 37 t (dried) ha-1 in the 5-month harvest season was produced from this culture system. Cultivation ofK. alvarezii var.tambalang in cages is possible, which indicates that seaweeds can be grown with carnivorous finfish, a practice which is still untapped.
