Abstract

ABSTRACTLipid Peroxidation by Paracetamol and Hot Water Extract of Green Tea (Camellia sinensis ) in Yeast Candida tropicalis preserved in Low Temperature. The use of C. tropicalis cell as a tool to evaluate antioxidant property of green tea to protect oxidative stress caused by paracetamol in cell level was investigated in our laboratory. Immediate availability of cell culture will significantly reduce the time of cell preparation. Low temperature preservation of cell culture is one of methods to produce cell cultures. However, low temperature might affectphysiological state of the cell. In this study, effect of low temperature preservation (4 ºC, 10 days) on the oxidative response of yeast cell treated with paracetamol and hot water extract of green tea had been investigated. Cells incubation with paracetamol 0.3 % for 2 h caused oxidative stress in both fresh and preserved culture since the content of a marker of oxidativestress, peroxyd lipids increased significantly. Whereas, concentration of peroxidised lipids in preserved cultures was lower than that of fresh culture. Increasing of peroxydized lipids followed with decreasing of cell viability in fresh culture but not in preserved culture. Green tea withconcentration of 0.1 % decreased peroxyd lipids in fresh cultures treated with paracetamol but not in preserved cultures. Green tea with concentration of 0.2 % or 0.4 % in increased peroxyd lipids in fresh cultures treated with paracetamol but not in preserved cultures. The data indicated that green tea did not show anti- or pro-oxidative effect in cultures preserved in low temperature treated with paracetamol. However, induction of super oxide dismutase (SOD), an antioxidant defense enzyme, was not observed in cell preserved in low temperature. The study revealedthat low temperature might make the cell more resistant against prooxidative properties of paracetamol.Keywords: C. tropicalis, oxidative stress, low temperature, paracetamol, green tea

Abstract

ABSTRACTExploration of Soil Actinomycetes Diversity from Ternate as Indigenous Antibiotic Sources.Actinomycetes of soil samples from Ternate, North Moluccas were isolated using SDS-YEmethod in humic acid vitamin agar. Ternate has high abundance of Actinomycetes, approximately6.00 – 487 x 104 CFU/ g soil, depends on habitat types. We have selected 60 isolates andconducted antibiotic screening against pathogenic bacteria and fungi using agar diffusionmethod and found both narrow and broad antibiotic spectrum types . Based on 16S rDNAanalysis, all Actinomycetes with antibiotic activities are belong to the genus Streptomyces. .Minimum Inhibitor Concentration (MIC) value was determined by broth microdilution method.It was found that MIC values varied, depended on microbial tested. We found two isolateswith higher antibiotic activity compared to the commercial antibiotics (chloramphenicol,erythromycin for antibacterial and nystatin, kabicidin for antifungal). Cell destruction analysiscaused antibiotic activities was conducted through leak of protein and nuclatic acid.Key words : Actinomycetes, soil, Ternate, antibiotic, cell distruction

ABSTRAKAktivitas Induksi Superoksida Dismutase dan Resistensi Etanol oleh Sodium Kloridadan Plumbum Asetat pada Khamir Candida sp. Y390. Untuk mengetahui sifat khamirCandida sp. Y390 dalam melindungi diri dari cekaman oksidatif, telah dilakukan risetkajian toleransi sel terhadap etanol dan hubungannya dengan enzim superoksida dismutase(SOD) pada khamir tersebut. Viabilitas sel yang ditumbuhkan pada media gliserol dandiinkubasi pada etanol 17,s % selama 1 jam adalah 0.30 f 0.09 % , pada media gliseroldan 1 1,7 % natrium khlorida adalah 1.65 f 0.5 % sedang pada media giserol dan 1 ppmplumbum asetat adalah 1.16 f 0.7 %. Aktivitas CuZnSOD pada sel yang diinduksi olehnatrium khlorida atau plumbum asetat turun sedikit, yakni masing-masing 1,7 dan 1,9kali. Aktivitas MnSOD pada sel yang diperlakukan dengan natrium khlorida naik sedikit(sekitar 1,03 kali), namun pada sel yang diperlakukan dengan plumbum asetat naik secaramenyolok (sekitar 3,6 kali). Data ini menunjukkan bahwa metabolisme etanol dapatmenyebabkan Candida sp. Y390 mengalami cekaman oksidatif. MnSOD khamir mungkinberperan dalam melindungi sel dari kerusakan akibat cekaman oksidatif.Keywords: Candida sp. Y390, yeast, ethanol metabolism, oxidative stress, SOD.

Abstract

ABSTRACTMonascus sp. MM was a contaminant fungus isolated from museum specimenpreserved with ethanol 70 %. In order to verify role of superoxide dismutase (SOD) inprotecting cell from ethanol toxicity during ethanol metabolism, SOD activities of Monascussp.MM and a Monmcus sp. NGK, which was isolated fiom fermented red rice (angkak), werecompared. When fungus was grown with glucose, CuIZn-SOD activity of Monascus sp., MMwas 7.1 times of thht of Monascus sp. NGK. Whereas in ethanol medium, CuIZn-SOD activityof Monarcus sp. MM was 24.6 times of that in Monascus sp. NGK. Induction of CuIZn-SODMonmcus sp. MM by ethanol was not observed. Compared with Mn-SOD, activity of CuIZn-SOD was markedly important (I 0 times of Mn-SOD when fungi grown with ethanol; 12 timeswhen the fungi grown with glucose). The data indicated that Cu/Zn-SOD might play animportant role in protecting cell fiom ethanol toxicity during ethanol metabolism. Ethanolrespiration rate of Monascus sp. MM was also important since O2 consumption and ethanoldegradation rates were clearly higher than that of Monascus sp. NGK.Keywords: Monarcw sp., superoxide dismutase, respiration, ethanol resistance.
