“…Porphridium cruentum is unicellular marine red micro algal (Rhodophyta) species (21). In P. cruentum, the presence of starch, carbohydrates and sugar monomers (glucose, xylose, methyl glucaronic acid) of polysaccharides makes it a potential carbon source (22) and the biomass consists of 32% (w/w) available carbohydrates and 34% (w/w) crude proteins (23). This showed that it could be a potent agent for removal of heavy metals.…”

Among a variety of microbial materials employed for biosorption, algae have added advantages of non-toxic and autotrophic nature. In this study, biosorption of Hg(II) was studied with red algal biomass of Porphyridium cruentum. The parameters affecting biosorption such as dosage of biosorbent, pH, contact time, initial metal concentration, temperature and effect of foreign metal cations in binary system were evaluated. Kinetic data were described with the help of pseudofirst-order and pseudo-second-order kinetic models. Langmuir, Freundlich, Temkin and DubininRadushkevich isotherm models were applied to adsorption equilibrium data. According to the results, the maximum removal capacity (q max ) was 2.62 mg/g observed at pH 7 with 0.25 g/L of biosorbent dosage for Hg(II) solution containing 10 mg/L of metal ions. The Langmuir isotherm model fits best to the adsorption data while the kinetic data followed the pseudo-second-order model. Thermodynamics studies showed that the biosorption process of Hg(II) on P. cruentum was exothermic in nature.ARTICLE HISTORY

“…S. platensis tolerated to a high Pb 2+ concentration, therefore able to remediate contaminated waters [ 23 ]. Soeprobowati and Hariyati (2013) had shown that the population growth of Porphyridium cruentum was high in the concentration of 1 mg/L Pb 2+ , Cd 2+ , and Cu 2+ . In the concentration of 3 mg/L Pb 2+ , Cd 2+ , and Cu 2+ .…”

“…Phycoremediation is the process in which algae are used to clean up the environment from pollutant [ 7 ]. Soeprobowati and Hariyati (2013) tent to used the term of phycoremediation for the used of microalgae to remediate environmental pollution [ 8 ]. Biological methods such as biosorption or bioaccumulation promote an advantages to physico-chemical methods on reducing the contaminant from the industrial effluent [ 9 ].…”

Phycoremediation is an application of algae for remediate environmental pollution by reducing or eliminating toxicity of such components in waste water. One of environmental problem in Indonesia is heavy metals pollution. Heavy metals are required by microalgae in a trace concentration, but in a high concentration heavy metals are toxic. Spirulina platensis is a microalgae belong to Cyanobacteria that has been used as a single cell protein, feed fish, and supplement. Many researchs on S. platensis had been done to optimize the product. Research on the use of S. platensis for remediation environmental pollution were also had been conducted. But, research on the use of local S. platensis to reduce the concentration of Pb 2+ , Cd 2+ , Cu 2+ and Cr 2+ , had not yet well developed. Therefore, this research was conducted in order to find out the effect of 1, 3, and 5 mg/L concentrations of Pb 2+ , Cd 2+ , Cu 2+ and Cr 2+ on the S. platensis population growth and its accumulation. A laboratory experiment was developed with those different concentrations with 3 replications and control. The initial concentration of heavy metals were measured as well as the 7 and 15 days treatment to determine the bioaccumulation of heavy metals by S.platensis . Based on this research, the concentration of 1 mg/L heavy metals may induced the population growth of S. platensis, due to improvement enzymatic process, the concentration of 3 mg/L heavy metals inhibit population growth, and the concentration of 5 mg/L heavy metals was toxic for S. platensis. Since S. platensis was found high tolerance to Pb 2+ , Cd 2+ , Cu 2+ and Cr 2+ at low concentration, it was recommended that for phycoremediation process using S. platensis more appropriate to be applied for low concentration contaminated water. It was suggested that S. platensis can be used as a metal absorbent and can be cultivated from wastewaters after phycoremediation process for other uses such as fertilizer, with the note that heavy metal contamination in waste water should not exceed 1 mg/L. S. platensis will be better if apply 15 days in contaminated wastewater to get the highest removal heavy metals.
