Salak fruit in Indonesia was produced by various cultivated varieties, one of which is sidempuan salak (Salacca sumatrana). Post-harvest destroying fungi the most causes yield losses on salak. The purpose this study to enumerate and pathogenicity postharvest As many as 1000 g fresh harvested used sample. Fungal population enumerated dilution method followed pour plate method. intensity infectio...

This paper illustrates the application of an untargeted metabolic profiling analysis of winery-derived biomass degraded using four filamentous fungi (Trichoderma harzianum, Aspergillus niger, Penicillium chrysogenum and P. citrinum) and a yeast (Saccharomyces cerevisiae). Analysis of the metabolome resulted in the identification of 233 significant peak features [P < 0.05; fold change (FC) > 2 a...

An extracellular thermostable xylanase (Xyl-IIb) produced by Penicillium citrinum isolate HZN13 was purified to homogeneity using DEAE-Sepharose, Sephadex G-100 and Bio-Gel P-60 chromatography with specific activity of 6272.7 U/mg and 19.6-fold purification. The purification revealed the occurrence of multiple forms of xylanases (Xyl-I, Xyl-IIa, Xyl-IIb and Xyl-III). The molecular mass of highl...

Purpose: To evaluate a green process for the extracellular production of silver (Ag) nanoparticles synthesized and stabilized using Penicillium citrinum isolated from soil. Methods: The pure colonies of Penicillium citrinum were cultured in Czapek dox broth. The supernatant of the broth was examined for the ability to produce silver nanoparticles. The reactions were performed in a dark compartm...

In optimization of cellulase production by different pH, substrates, nitrogen, carbon sources were detected from penicillium citrinum micro-fungal species. The maximum cellulase activity was recorded in the range of pH5 to 6.5 and wheat bran (91 U/ml) and rice bran (81 U/ml) is the best raw substrate for the production of cellulase. Estimation of extracellular protein was recorded in different ...
