Abstract

Degenerative diseases occur due to damage to cells, fat tissue, and the immune system caused by several factors. One theory that causes degenerative diseases is the presence of free radicals. The Snake plant is one of the plants in Indonesia that has long been known as a plant that is useful as anti-free radicals. The research was conducted by isolating and purifying endophytic fungi and determining the autogram profile of free antiradical activity from The Snake plant. From the purification results obtained 7 isolates, followed by macroscopic examination and fermentation of each isolate. The results of the screening test showed that 2 fermentates were active as anti-free radicals, namely AF 1 and AF 3. Fermentate isolates AF 1 and AF 3 were identified by TLC-autography using a mixture of n-hexane: ethyl acetate (7:1). TLC-autography test results by spraying DPPH isolates AF 1 and isolates AF 3 showed yellow spots on a purple background with Rf1 values ​​of 0.90 and Rf2 of 0.2 in AF1 isolates and Rf1 values ​​of 0.83 and Rf2 of 0.16 on AF3 isolates. potential as anti-free radicals. From the results of this study, it was concluded that there was anti-free radical activity in the Snake plant.

Abstract

Tobacco is grown intensively in the North Western region of Bangladesh. The farmers in that region in Bangladesh receive less production of the next crop of tobacco and experience economical loss. We aimed to determine the impact of tobacco cultivation in soils. In order to determine the impact of tobacco cultivation in soil, 20 soil samples (10 from tobacco cultivated land and 10 from non-tobacco cultivated land) were collected from the study area. The samples were analyzed for soil pH, organic matter, humidity, macronutrients (N, P, K, S, Ca and Mg) and micronutrients (Zn, Fe, Mn, Cu and B). The concentration of available phosphorus (23.22 µg/g), total nitrogen (0.084 %), calcium (798 µg/g), magnesium (438 µg/g), zinc (1.00 µg/g), manganese (1.70 µg/g) boron (0.17 µg/g) including soil pH, organic matter and humidity showed higher values in tobacco cultivated land than those of the non-tobacco cultivated land. In contrast, concentration of total potassium (148.2 µg/g), available sulfur (5.45 µg/g), copper (2.40 µg/g) and iron (10.82 µg/g) in tobacco land showed lower values than those of the non-tobacco land. Soil magnesium level increased with increasing pH although the potassium level decreased with the increase of pH of the tobacco cultivated soils.

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

This study aims to extract and compare the chemical properties of gelatin from the skin and bone of yellowfin tuna (Thunnus albacares) by using the acid method. The proximate and FTIR analyses of tuna skin and bone gelatin (TSG and TBG) were conducted to determine their chemical properties. The acid condition successfully produced gelatin, which is 3.24% of TSG and 2.61% of TBG yields. The proximate properties revealed that both extracted gelatin BEG and CG fulfil the Indonesian standard quality of gelatin, with a high level of total protein and low lipid content. Amide A, I, II, and III were shown at 3452.58, 1637.56, 1517.98, and 1240.23 cm-1 respectively in TSG FTIR spectra, and at 3493.09, 1660.71, 1533.41, and 1238.30 cm-1, respectively in TBG spectra. Both skin and bone of yellowfin tuna can potentially be used in the production of gelatin for industrial and pharmaceutical purposes with further optimation.

Abstract

Uric acid is a compound produced from purine metabolism. The excess amount of these compounds could causes diseases in the body. Effective and practical methods are needed for early detection of uric acid. Technically, uric acid could be detected using enzymes (enzymatic) and without enzymes (non-enzymatic). Several methods have already reported for uric acid detection in biological samples, including fluorimetry, colorimetry, liquid chromatography, flow injection analysis, chemiluninescence, and electrochemical detection. Among electrochemical detection methods, voltammetry is one of the most prospective for uric acid detection. This review covers the approach of uric acid detection including enzymatic and nonenzymatic approach, several voltametric technique for uric acid detection, and screen printed and modified electrode as platform for uric acid detection. Analytical performance such as linear range, sensitivity, selectivity and reproducibility of uric acid detection using various voltametric method and at different platform were also highlighted.

Abstract

Terpenoid compounds known as essential oils can be used as flavour enhancers and medicinal sources. The Citrus genus is a citrus aurantifolia species. Citrus aurantifolia (Rutaceae) is a fruit type most often consumed by the public. This study aimed to determine the terpenoid compounds contained in lime peel extract (C. aurantifolia). This study used the extraction method for 3 x 24 hours and then continued by using a sonicator. The viscous extract was then analyzed by using a GCMS method. This study obtained that the β-pinene compound for the retention time was 7.92, and the per cent area was 34.81 %. While for the D-limonene compound for the retention time was 6.62, and the per cent area was 20.15 %

Abstract

Molecularly Imprinted Polymers (MIP) are polymers with active sites that can recognize target molecules selectively. This study aims to determine the kinetics and adsorption capacity of MIP_DBP. The method used in the synthesis of MIP_DBP was precipitation polymerization using methacrylic acid (MAA) monomer, Ethyleneglycol Dimethacrylate (EGDMA) cross linker, DBP as a template molecule, and toluene as a solvent. The MIP_DBP obtained is a white solid. The results of the MIP_DBP adsorption kinetics test followed the pseudo-second-order kinetics model and the adsorption capacity according to the Freundlich isothermal adsorption model with the adsorption capacity value for DBP was 9.38 mg/g.
