Abstract

The use of sponge symbionts bacteria as marine biomaterials in the heavy metal bio-adsorption method is an effort to save the marine environment from contamination of heavy metal contaminants. The ocean is a giant container, most vulnerable to contamination of pollutants. The target of the research is to determine the potential, capacity and pattern of bio-adsorption of sponge symbionts bacteria against various pollutants so that the toxic properties of heavy metal contaminants can be minimize. The method used is to interact with the bacterial suspension on the test metal concentrations that have been determined. The parameters measured were optical density, pH and concentration of heavy metals after the interaction lasted several days and the calculation of capacity, efficiency and bio-adsorption patterns of bacterial isolates from sponges. Results: The pattern and bio-adsorption power of AC bacteria to Cr and Mn ions were higher than AC bacteria, the adaptability of AC and BS bacteria was stronger in Cr (III) contaminated media compared to Cr (VI) toxic media, causing bacterial cell population BS and AC in Cr (III) and Mn (II) media are more abundant than in Cr (VI) and Mn (VII) media, capacity and bio-adsorption efficiency of BS and AC bacteria agains Cr (III) ˃ Cr (VI) ions and Mn (II) ˃ Mn (VII), It is suspected that there is an influence of reactivity and toxic properties of the metal ion test on the performance of the sponge symbionts in bio-adsorption

Abstract

Heavy metal pollutants and polycyclic aromatic hydrocarbon contaminants, also known as PAHs, need attention from related parties, considering that their use is very wide, as well as their relatively high natural releases. Careless and uncontrolled handling has the potential to cause problems for creatures, especially in marine ecosystems. The aim of the study was to determine the performance of marine sponge microsymbiont isolates in heavy metal biosorption and PAH biodegradation. The method applied, pure isolates of marine sponge symbionts were cultured on NA media. The suspension of isolates was made using physiological 0.9 % NaCl solution. Suspension adapted 24 hours. The isolate suspension was interacted with heavy metals Cd2+ and As3+, each with a concentration of 100 ppm and naphthalene and anthracene with a concentration of 1000 ppm. Interaction time of 5, 10, 15, and 20 days. Results of the analysis showed the biosorption capacity of the bacterial isolate Sp6.B2 to Cd2+ = 83.190 %, while Sp8.B1 = 82.240 %. Biosorption performance of Sp6.B2 isolates against As3+ = 99.890 %, while Sp8.B1 = 99.894 %. The biodegradation performance of Sp6.B2 isolates had a higher aggressiveness towards naphthalene and anthracene test contaminants than Sp8.B1 isolates. These results indicate that the biosorption performance of Sp6.B2 ˃ Sp8.B1 isolates against Cd2+ contaminants and vice versa Sp6.B2 ˂ Sp8.B1 against As3+ biosorption, while the biodegradation performance of Sp6.B2 ˃ Sp8.B1 isolates both against naphthalene and anthracene test contaminants

Abstract

Today's marine tourism is experiencing rapid growth to meet the global needs of the world's population. Exploitation of marine biological wealth is no less important because it involves human life. The marine ecosystem must be of high quality and free from exposure to toxic pollutants, such as PAHs. The marine ecosystem must be of high quality and free from exposure to toxic pollutants, such as PAHs, microplastics. This research aims to provide data and information about the types and abundance of aromatic hydrocarbon compounds in sediments, sea water and marine biota around KKI waters. The analytical method to meet these objectives uses GS/MS. The status of marine tourism areas, especially around KKI waters, is declared polluted by PAHs. The types of PAHs identified in each sample at the three sampling stations were dominated by naphthalene (NL), phenanthrene (PT), pyrene (PR) and azulene (AZ). The average total abundance of PAHs in sponge samples (±70.51%), sediments (±67.30%), followed by seawater samples (±64.85%), starfish samples (±41.80%) and fish (±26.74%). The NL type PAHs were found in all types of samples and at all stations, where the PAHs were thought to originate from industrial, hospital, and household activities. The status of marine tourism, especially around the KKI waters, for tourists needs to be careful and alert, because the KKI area is not completely free from harmful and toxic pollutants, so it is a risk to health. Makassar City TMA managers are encouraged to make efforts to reduce the rate of increase in the concentration of regional PAHs, such as providing periodic data and information about harmful pollutants, education for every tourist to care about waste and planting coastal plants such as mangroves which have a biofilter function against toxic pollutants.
