Abstract Cellulolytic bacteria is one of the beneficial bacteria that can found in mangrove ecosystem. The purposes of study were to analyse the cellulolytic index, and to analyse the cellulase activity of bacteria isolated from soil mangrove. Qualitatively, assessment of cellulase activity were carried out at the Microbiology laboratory of Fish Quarantine Station, Quality Control and Safety of Fishery Products (SKIPM) Aceh, while quantitatively was observed in microbiology laboratory, Biology Department, IPB. Assessment of qualitative cellulase activity is performed by growing the selected pure isolate on 1% CMC medium then spilled 1% congo red to test its cellulolytic potential. Cellulolytic potential was determined by clear zone performed around the colony after congo red flooded. The quantitative cellulase enzyme activity test carried out by DNS method tested on one selective isolate. There were 21 from 39 isolates showed a clear zone isolated from mangrove soil. The cellulolytic index (CI) obtained ranged from 0.07 to 0.80 classified as low cellulolytic index criteria. The cellulolytic index was higher in bacteria isolated from mangrove rehabilitated than mangrove unrehabilitated. The highest cellulase activity and specific cellulase activity of BTMD32 was at 48 hours with the value were 0.0012 U/ml, 0.077 U/mg, respectively. The result concluded that the bacteria cellulolytic isolated from mangrove soil had low cellulolytic index, low cellulase activity, and low specific cellulase activity.

Cellulolytic bacteria that produce cellulase enzymes play an essential role in degrading cellulose in their habitat. The presence of cellulolytic bacteria strongly supports the fertility and productivity in mangrove waters. The objectives of the study are to analyze the activity of cellulase enzyme qualitatively through the cellulolytic index and quantitatively through the activity and specific activity of the cellulase enzyme from bacteria isolated from the water of mangrove ecosystems in Aceh Province. The qualitative experiment of enzyme activity was carried out at the Microbiology laboratory SKIPM Aceh, and a quantitative experiment of enzyme activity was conducted at the Microbiology Laboratory, Biology Department, IPB. Isolation of cellulolytic bacteria isolated from mangrove water used Carboxy Methyl Cellulose (1% CMC) selective media and carried out by spread plate method. The ability of bacteria to produce cellulase was tested qualitatively using the spot technique, this test was carried out using 1% Congo Red. Furthermore, the quantitative testing of cellulase enzymes activity adopted the DNS spectrophotometric method. The specific activity of the cellulase enzyme can be determined by using the Lowry method. There were 21 isolates that had a clear zone and had the ability to produce cellulase enzymes from 49 isolates that were successfully purified. The highest cellulolytic index (CI) produced using BAM421 isolate with the value of 5.50 was included in the high category, followed by BAM326 and BAM132 isolates, with values of 1.55 and 1.05 were categorized into the medium category. The other isolates were in the low cellulolytic index category. The isolate with the highest CI value was further tested using the quantitative enzyme activity test. The highest cellulase enzyme activity of BAM421 occurred at 24hr (0.0029 U/ml). The highest specific cellulase activity of BAM421 was at 24hr with the value of 0.210 U/mg. The result concluded that the qualitative test showed CI values can be categorized into low, medium, and high. Moreover, the value of the quantitative assay described that the cellulase enzyme and the specific enzyme activities of the bacteria were low in the study area.Keywords:Cellulolytic indexQuantitative testMangrove watersCellulase enzymeMicroorganismTRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian //  TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//

Introduction:Azomonas agilis, a nitrogen-fixing bacterium, was isolated from rhizospheric soil in central Myanmar.Methods & Materials:The nitrogen-fixing activity of this bacterium was detected by plate screening method using glucose nitrogen free mineral medium and ammonium test-kit Cellulolytic activity was screened by plat assay and detected by Dinitrosalicyclic acid method (DNS).Results & Discussion:The isolatedA. agilisgrew in media containing 3-12% of NaCl, although the growth became poor when NaCl concentrations increased. Among various carbon sources, sucrose was the best source for ammonium accumulation of this bacterium, whereas arabinose was not the suitable carbon source. Although the nitrogen-fixing activity ofA. agiliswas highest after one week incubation, cellulase enzyme production was highest after 2-3 days of incubation. It was observed that cellulase enzyme activity ofA. agilisfor cellulose and sodium carboxymethyl cellulose (CMC) was almost the same. Three agricultural wastes were used to detect the cellulase enzyme activity ofA. agilis, cellulase activity was better on filter paper as a substrate when compared to rice-straw and sawdust.Conclusion:So, the isolatedA. agilishas high potential as an effective bacterial strain to use in sustainable agriculture and degradation of some agricultural residues.

Red-mature Tabasco (Capsicum frutescens) fruit (`McIlhenny Select') normally separate easily at the junction of the fruit and receptacle or calyx. Differences in fruit detachment force (FDF) between two lines, one that separates readily (`McIlhenny Select') and one that does not (`Hard Pick'), have been reported previously (Motsenbocker et al., 1995). In this study, enzyme activity from the detachment area was analyzed by viscosity reduction. The reaction mixture was 0.3% pectin in 20 mm NaAc, pH 5.5, for polygalacturonase (PG) and 0.6% carboxymethyl cellulose (CMC) in 20 mm NaPO4, pH 6.0, for cellulase. Preliminary data indicated that PG and cellulase enzyme activity increased during fruit ripening in both lines. Only cellulase activity, however, correlated with FDF. In addition, the activity of both enzymes was higher in the `McIlhenny Select' line than the `Hard Pick' line at the orange and red-mature stages.
