Abstract:
... Electrostatic dust cloths have previously been used to study microorganisms in settled dust by placing the cloths horizontally on surfaces (called Electrostatic Dust Collectors, EDC). In this study, we investigate whether the same cloths, henceforth called ‘E-Cloths’, can be used to study accumulation of microorganisms and endotoxin on workers’ clothes. This was studied as current methods have lim ...

Abstract:
... Ochratoxin A (OTA), one of the most important mycotoxins, is mainly produced by fungi in the genera Aspergillus and Penicillium, and commonly found in food and agricultural products. In addition to causing significant economic losses, the occurrence of OTA in foods poses a serious threat to human health. Therefore, it is very important to develop approaches to control or detoxify OTA contamination ...

Abstract:
... Two pairs of undescribed enantiomers including a 2,5-diketopiperazine namely (±)-janthinolide G and a related analogue (±)-janthinolide H, were isolated from the crude extract of the fungus Penicillium griseofulvum together with five known compounds. Both two structures were determined by spectroscopic method and HRESIMS, whereas absolute stereochemistry was elucidated by using theoretical NMR cal ...
... Filamentous fungi are used in the dairy industry as adjunct cultures in fermented products, but can also lead to food spoilage, waste and economic losses. The control of filamentous fungi with abiotic factors contributes to longer food shelf life and prevention of fungal spoilage. One of the main abiotic factors for controlling fungal growth in foods is water activity (aw). This study aimed to eva ...
... In this study, we investigated the antifungal activity of lactose oxidase (LO) as a potential biopreservative in dairy products. Our study objectives were to screen antifungal activity of LO against common mold strains, to detect the minimum inhibitory level of LO against the same strains, and to understand how LO affects the pH and lactic acid bacteria (LAB) counts in set yogurt. Five mold strain ...

Abstract:
... Given the importance of lactic acid bacteria (LAB) in dairy products, this study assessed the antimicrobial properties of lactobacilli against some toxigenic Penicillium spp and pathogenic bacteria commonly found in cheese. Lactobacilli previously isolated from an artisanal Brazilian cheese (n = 32) were identified to species level by amplification and sequencing of the 16S rRNA gene and tested ag ...
... The pre-harvest applications of antagonists are promising strategies to minimize various postharvest diseases. Given this, we sought to evaluate the capability of Pseudomonas fluorescens ZX in inducing resistance of postharvest citrus fruit against blue and green molds, caused by Penicillium italicum and Penicillium digitatum, respectively. Results showed that pre-treatment with P. fluorescens ZX ...

Abstract:
... In order to explore the effect of the C-terminal loop domain of Penicillium expansum lipase (PEL) on its regioselectivity and activity, homologous substitution and site-directed saturation mutagenesis were used. Two mutants PEL-loopAO and M234F were selected to catalyze the hydrolysis of tricaprylin and the molar ratios of 1,2-dicaprylin to 1,3-dicaprylin in the products were 25.57 and 8.57 respec ...
... The ripening process of fermented/dry cured foods is considered a favourable stage for the development of filamentous fungi on the product’s surface. In general, some species are beneficial, as they contribute to the aroma and flavour characteristics, while some species such as Aspergillus westerdijkiae, Penicillium brevicompactum, Penicillium griseofulvum, Penicillium nordicum, and Penicillium ve ...

Abstract:
... Two new azaphilones, penicilazaphilones F (1) and G (2) together with two known analogs (3 and 4), were isolated from fermentation cultures of the marine-derived fungus Penicillium sclerotiorum E23Y-1A. Their structures were elucidated based on spectroscopic methods, including IR, MS, 1D and 2D NMR, as well as by comparison with published data. The absolute configuration of compound 1 was unambigu ...
... Citrus (Citrus spp.) species produce a variety of fruits that are popular worldwide. Citrus fruits, however, are susceptible to postharvest decays caused by various pathogenic fungi, including Penicillium digitatum, Penicillium italicum, Geotrichum citri-aurantii, Aspergillus niger, and Aspergillus flavus. Decays resulting from infections by these pathogens cause a significant reduction in citrus ...

Abstract:
... The pressing need for novel chemical matter to support bioactive compound discovery has led natural product researchers to explore a wide range of source organisms and environments. One of the implicit guiding principles behind those efforts is the notion that sampling different environments is critical to accessing unique natural products. This idea was tested by comparing fungi from disparate bi ...

Abstract:
... Green mould, caused by Penicillium digitatum, is the major postharvest disease of citrus in all producing countries. The control of this disease is carried out by fungicides in postharvest treatments, which can leave toxic residues in fruits. Therefore, the interest in cleaner technologies and alternatives to the use of fungicides, such as biopesticides, has grown in recent years. Conyza canadensi ...
