Abstract

Aspergillus niger is pathogen fungi that can live in various locations and can live contiguous with many hosts, one of them is queen termite’s nest. The aims of the study were to isolated the secondary metabilite of A.niger. Extraction proccess of secondary metabolite compounds was carried out by maceration method using methanol solvent. Based on that proccess, methanol extract was be yield 4,32% sample weight. Fractination proccess was carried out in the separating funnel using ethyl acetate solvent, which ethyl acetate fraction was be yield 14.39% methanol extract. Separation of the compounds was carried out by column chromatography method using n-hexane and ethyl asetate eluents. Purification of the compounds were done by recrystallization method using n-hexane and ethyl asetate. Two secondary metabolite compounds were successfully isolated from ethyl acetate fraction of the methanolic extract of fungus A. niger “In-Habiting” queen termite’s nest M. gilvus Hagen. Based on organoleptic examination, the compound signed AM-12-22-01 is 35 mg, white needle crystals, melting point 151-153 oC. While, the AM-12-60-01* is 15 mg, white needle crystals, melting point 91-93 oC. Based on the chemical analysis, thin layer chromatography, ultraviolet and infrared spectra data it was identified that AM-12-22-01 and AM-12-60-01 were a phenolic compounds.Key words: isolation, A. niger, In-Habiting, M. gilvus Hagen.

Abstract

This study provides an overview of the potential of endophytic fungi isolated from leaves, stems, mangrove roots A. marina as a producer of antibiotics tested for Staphylococcus aureus, Escherichia coli, Candida albicans. This research was carried out in the microbiology laboratory of the Health Polytechnic of the Ministry of Health of Riau from March to June 2017. This study used a laboratory experimental method, the data presented in descriptive form. The stages of the study were: identification of A. marina plants, fungal isolation, qualitative tests of flavonoids isolates from endophytic fungal, and antibacterial activity test. The results showed that from 15 isolates of endophytic fungi, 5 isolates producing antibiotics. FAA 3 isolate showed the highest antibiotic activity with 24 mm the diameter of the inhibitory zone, while the lowest inhibition zone was FAA 4 isolate by forming a diameter of inhibitory zone of 7 mm and the results of qualitative tests of metabolites showed as secondary flvonoid metabolites. This research can be used as a source of information for the community in utilizing mangrove plants as an alternative in improving health.

Abstract

Research about exploiting of straw as component of ethanol as fermentation based on difference able of inoculums consentration and fermentation time has been studied. Straw utilized in this research is result of agriculture raffle from rice plant type IR 46, which taken away from rice field the district of Lubuk Minturun, Padang. The first, stage hydrolysis was done to straw using H2SO4 P 1% with various time 30, 60, 120, 180 and 240 minute and determined glucose produced for each sample. The fermentation of ethanol by using Saccharomyces cereviceae bacterium were conducted at temperature 30ºC with speed 100 rpm. Sampling was taking every 6 hours (6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66). The inoculum’s grade level is variation by 1, 2, 3% v/v. Results showed that the optimum hydrolysis time wich mark by highest glucose rate is minute 240 with grade level 0.7765 %. The highest ethanol grade of which can be yielded with inoculum 1% was 0.02066 % v/v at yeast inoculum 2 % was of 0.02549 % v/v and yeast inoculum 3 % was of  0. 07804 % v/v.

Abstract

The antimicrobial activity of endophytes microbe that symbiosis with mangosteen had been carried out. There were 12 fungal’s  isolates and 14 bacterial’s isolates had been isolated from cortex, lief, and pericarp of Garcinia mangostana L. Each fungal’s isolates were fermented in Soybean Extract Broth liquid medium for 1 week at on a rotary shaker incubator at a 25-270 C and 90 rpm speed. Each bacterial’s isolates were fermented in water corn soaked medium for 24 hours on a rotary shaker incubator at 300C and 120 rpm speed. Fermented fungal’s and bacterial’s were tested their antimicrobial’s activity against Staphylococcus aureus, Escherichia coli and Candida albicans with agar diffusion methode. The result showed that J-G1 (Candida sp) and J-T1 (Candida sp) were fungal’s isolates that ware active against Escherichia coli with inhibition diameter 10 mm. J-H1 (Curvularis sp), J-G2 (Candida sp), J-T1 (Candida sp) were fungal’s isolates that were active against Staphylococcus aureus with inhibition diameter 9 mm, 11 mm and 13 mm respectively. B-T2 (Klebsiella sp)and B-K51 (Bacillus sp1) were bacterial’s isolates that were active againts Escherichia coli with inhibition diameter 13 mm and 18 mm respectively. B-H (Bacillus sp2), B-G (Bacillus sp2), B-P1 (Bacillus sp1), B-K101(Bacillus sp1) and B-K102 (Bacillus sp1) were bacterial’s isolates that were active againts Staphylococcus aureus with inhibition diameter 11 mm, 14 mm, 15 mm, 16 mm and 15 mm respectively.

Abstract

The formulation of leaf´s murbey ethanol extract´s toothpaste and its activities against dental plaque´s bacteries had been done. Pre test showed the leaf´s murbey ethanol extracts at 4% of concentration gave an optimal diameter of inhibition against dental plague. Based that fact, this research would have made 3 formulas at toothpaste from leaf´s murbey extract at 1%, 2%, and 4% of concentration. All of formulas would have wade with the same base of toothpaste. All of formulas would be characterized of pharmaceutic´s properties and antibacteria´s activities, that would be compared with toothpaste “S” and “P” as a standard. The result shawed all formulas gave a good characteristic of pharmaceutic properties. F3 had gave a good diameter of inhibition, that was 21.875 mm, where as the “S” and “P” of toothpaste had gave a diameter of inhibition respectively 23.875 mm and 22.75mm. There was a significant difference of inhibition´s diameter of all formulas at 0.05 level of confidence.
