Abstract

Reactive black 5 (RB5) is an azo dye widely used in the textile industry for dyeing fabrics. It is categorized as a recalcitrant dye that is hard to degrade and an environmental pollutant. Therefore, textile waste effluents containing this dye must be treated to remove or degrade the dye, before being released into the environment. One method that can be used to degrade synthetic dyes such as RB5 is to use biological methods, by directly using live fungal cells or using laccase enzymes. Trichoderma asperellum LBKURCC1 is a filamentous fungus isolated from cacao plantation soil in Riau, Indonesia, and it is a laccase enzyme producer. To be able to determine the ability of T.asperellum LBKURCC1 life cultures to decolorize RB5 dye, several RB5 dye removal tests were carried out. Incubation of 50 ppm RB5 with life cultures of T. asperellum LBKURCC1 at room temperature (30°C, pH 6.5) for 24 hours resulted in 22% bioremediation, 3.2% biosorption and 19.1% biodegradation of the RB5 dye. The results of this study show that the live culture of T.asperellum LBKURCC1 is capable of biodegrading RB5. This is indicated by the degradation of RB5 by extracellular enzymes produced by these filamentous fungi.

Abstract

The increasing resistance of pathogenic microbes to antibiotics is a major public health concern, necessitating the discovery of effective antimicrobial compounds. The aim of this study was to assess the bioactive metabolites produced by Aspergillus fumigatus LBKURCC269 and Bacillus paramycoides LBKURCC218 under three fermentation conditions: monoculture of each microorganism and their co-culture. Metabolite analyses initiated with gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-high-resolution mass spectrometry (LC-HRMS) followed with molecular networking–Global Natural Products Social Molecular Networking (GNPS) and molecular docking. Antimicrobial activity of the extracts was then conducted. Metabolite analysis using GC-MS identified key antimicrobial compounds, including 2,6-bis(1,1-dimethylethyl)-4-methylphenol, pentadecanoic acid, cyclopropane pentanoic acid, and 3-piperidinol. LC-HRMS, combined with multivariate analysis and GNPS molecular networking, revealed additional antimicrobial compounds, including novel pyrazine derivatives induced in co-culture fermentation. Molecular docking analysis of 3-(propan-2-yl)-octahydropyrrolo[1,2-a]pyrazine-1,4-dione demonstrated its potential as an antimicrobial agent by inhibiting topoisomerase IV and cytochrome monooxygenase with binding affinity of -5.34 kcal/mol and -5.6 kcal/mol, respectively. The antimicrobial assays showed that the co-culture fermentation extract had the strongest activity, with inhibition zones of 20.33±0.59 mm (Escherichia coli), 14.33±0.59 mm (Staphylococcus aureus), and 25.67±0.59 mm (Candida albicans). This study highlights the advantages of co-culture fermentation in enhancing the discovery of antimicrobial compounds. The findings underscore the potential of this approach to simplify chemical isolation and accelerate the identification of novel antimicrobial agents for pharmaceutical development.

Abstract

As the prevalence of type 2 diabetes mellitus continues to increase over the years, research into antidiabetic drugs needs to continue. Probiotics are non-pathogenic microorganisms that have potential as α-glucosidase inhibitors. This study aimed to characterize and determine the α-glucosidase inhibitor activity of LBSU9 isolate, a probiotic isolated from "trites," a traditional food of North Sumatra. The results showed that LBSU9 had bacillus morphology, Gram positive, negative catalase test, TSIA (Triple Sugar Iron Agar) A/A test and non-hemolysis. LBSU9 had good tolerance to simulated gastric acid and bile salts, with growth percentages of 66.54% and 64.74%. LBSU9 also has potent antimicrobial activity against S.aureus and E.coli, with 20 mm and 17 mm inhibition zones, respectively. The alpha-glucosidase inhibitor activity of LBSU9 was 98.4% greater than that of acarbose, which was 97%. Based on the results of this study, it is concluded that LBSU9 isolate has the potential to be a complementary therapy to prevent or treat type 2 diabetes mellitus
