The aim of this research was to determin growth of Chlorella vulgaris on media added with Pb at different concentrations, and to determine the ability to absorb Pb. The experimental method was conducted by using concentrations of Pb at 3 different levels consisting of 1 ppm, 5 ppm, 10 ppm in triplicate and control treatment without the addition of Pb. Each sample was analyzed by ICP-OES (Inductivly Coupled Plasma â€“ Optical Emission Spectrometer). Data was analyzed by using ANOVA followed by LSD test. The growth of C. vulgaris biomass during the cultivation were Pb 1 ppm (10.38 g / l), k (9.10 g / l), Pb 5 ppm (8.36 g/l) and Pb 10 ppm (7.13) g/l). ANOVA test showed that different concentrations of Pb gave a very significant difference (Sig. <0.05) on the growth of C. vulgaris. Reduction in the concentration of Pb metal in culture media were Pb 10 ppm (96.8%), Pb 5 ppm (96.2%), Pb 1 ppm (90%) and there is no Pb found in control. ANOVA test results showed that C. vulgaris had a very significant effect (Sig. <0.05) on the decrease of Pb metal concentration. This shows that C. vulgaris has the capacity as bioremediation of Pb with different concentrations.

Litter from the weathering of dead mangrove stems and leaves contains a lot of starch which has potential to be degraded by amylolytic bacteria into simple compounds with the help of the amylase enzyme. Amylolytic bacteria are bacteria that hydrolyze starch into simpler compounds namely glucose with the help of the amylase enzyme. This study aims to 1) isolate, identify and test sensitivity of amylolytic bacterial isolates found at the Purnama Dumai Marine Station, 2) the ability of amylolytic bacterial isolates to inhibit the growth of pathogenic bacteria (Escherichia coli, Pseudomonas aeruginosa and Vibrio alginolyticus) and 3) to determine the of amylolytic bacterial species by 16S rRNA sequence analysis. The results showed 10 bacterial isolates (TR 2, TR 6, TR 7, TR 9, TR 11, TR 13, TR 15, TR 16, TR 18 and TR 20) were able to inhibit the growth of pathogenic bacteria (E.coli, P.aeruginosa and V.alginolyticus). The sensitivity test of isolate TR 20 against E.coli was categorized into weak with inhibition zone diameter of 4.65 mm. Sensitivity of isolate TR 6 against P.aeruginosa was categorized into medium with inhibition zone diameter of 5.22 mm. Then sensitivity of isolate TR 11 against V.algynolyticus was categorized into medium with inhibition zone diameter of 5.55 mm. DNA analysis using 16S rRNA method and BLAST analysis showed similarity of each isolate. Isolate TR 6 was similar to Bacillus paramycoides strain MCCC 1A04098, isolate TR 11 was in a group of Enterobacter cloacae strain ATCC 13047 and TR 20 was in a group of Vibrio harveyi strains of NBRC 15634.
