Abstract:
... We studied the endolichenic fungal communities from saxicolous lichens occupying the cobbles at Nahal Boker, the central Negev Desert, Israel. Overall, 101 species belonging to 64 genera were isolated from 12 lichen species collected in three seasons from the south-facing slope (SFS) and north-facing slope (NFS) of the wadi. The endolichenic communities possessed a set of traits, which helped them ...

Abstract:
... Fungal endophyte community amplicon sequencing can lose a significant number of informative reads due to host-plant co-amplification. Blocking of plant-specific sequences with peptide nucleic acid (PNA) clamps has been shown to improve metrics of detected microbial diversity in studies targeting 16S and 18S regions of rRNA genes. However, PNA clamping has not been applied to the plant ITS region o ...

Abstract:
... The microbial communities of kefir grains and kefir were evaluated over time using high-throughput amplicon sequencing. It was found that Lactobacillus kefiranofaciens and Lentilactobacillus kefiri consistently dominated kefir grains, whereas Lactococcus lactis dominated kefir. Many other bacteria and yeasts were detected that comprised the minor population of kefir grains and kefir. The community ...

Abstract:
... As a common practice in agricultural system, straw return has been reported to release a large number of trace gases and attracted much attention. However, the role of straw return in toluene emission remains poorly understood. In this study we measured the emissions of toluene as well as other 50 volatile organic compounds (VOCs) from wheat straw return for 66 days under flooded and non-flooded c ...

Abstract:
... Antibiotic pollution imposes urgent threats to public health and microbial-mediated ecological processes. Existing studies have primarily focused on bacterial responses to antibiotic pollution, but they ignored the microeukaryotic counterpart, though microeukaryotes are functionally important (e.g., predators and saprophytes) in microbial ecology. Herein, we explored how the assembly of sediment m ...
... Wooden vats are used in the production of some traditional cheeses as the biofilms on wooden vat surfaces are known to transfer large quantities of microbes to cheese. However, very few studies have investigated the microbial composition of biofilms on newly developed wooden vats and how communities assemble and evolve. In the present study, the microbial communities of biofilms were characterized ...
brown-rot fungi, etc ; DNA barcoding; Gloeophyllum trabeum; Picea abies; decayed wood; forest litter; lignocellulose; woody biomass; Show all 8 Subjects
Abstract:
... In forest ecosystems, fungi are the key actors in wood decay. They have the capability to degrade lignified substrates and the woody biomass of coniferous forests, with brown rot fungi being common colonizers. Brown rots are typically involved in the earliest phase of lignocellulose breakdown, which therefore influences colonization by other microorganisms. However, few studies have focused on the ...

Abstract:
... Non-destructive identification of the fungal disease has great importance as one of the challenges of the citrus post-harvest industry. In order to identify the fungal disease of Alternaria alternata, which occurred internally, the reflectance spectra were collected in 3 areas of the stem-end, equatorial and stylar-end of healthy and fungus-infected oranges using VIS-NIR spectrometer (400–1100 nm) ...
... Basidiomycota brown rot fungus (Fomitopsis pinicola) and two white rot fungi (Phlebia radiata, Trichaptum abietinum) were cultivated on thin slices of spruce wood individually and in interspecies combinations. Within 12 months, F. pinicola substantially decomposed spruce wood observed as mass loss, also in three-species combinations. However, white rot fungi through hyphal interactions negatively ...
... Aflatoxins are strong carcinogenic and mutagenic fungal metabolites, and aflatoxin contamination is a critical issue in agriculture and food production. Natural flavonoids can suppress aflatoxin biosynthesis; however, the structure–activity relationship remains unclear. In the present study, a total of 36 structurally related natural flavonoids were tested against the aflatoxigenic Aspergillus fla ...

Abstract:
... Monostichella coryli is the causal agent of the hazelnut anthracnose. The increase in the incidence in hazelnut orchards observed during recent years in Central Italy is increasing the need for information and studies on its biology and ecology, and how environmental factors (e.g., temperature) influence its development. For this purpose, seven isolates from different provenances of M. coryli were ...

... Penicillium expansum is the main cause of blue mold disease and the main producer of patulin in apple-derived products. This fungus also produces a wide variety of secondary metabolites, including citrinin and chaetoglobosin A. Secondary metabolism is regulated by global transcription factors that are affected by environmental signals. The light-dependent global transcription factor VelB, a member ...

Abstract:
... The paper outlines a procedure based on ultra-high performance liquid chromatography-electrospray ionization-tandem mass spectrometry and QuEChERS pretreatment for the determination of patulin in selected berries and stone fruits. The mycotoxin was determined in the positive electrospray ionization mode utilizing the formation of its methanol adduct. The method was validated for 4 fruit matrices: ...

Abstract:
... Soil moisture (SM) is one of the most limited factors on the Loess Plateau, but its effects on the microbial community and respiration are still unclear. To investigate the effects of stepwise wetting and constant SM on the soil microbial community and respiration rates, eroded soil under afforestation on the Loess Plateau was examined. The soils were sampled and incubated with constant gravimetri ...

Abstract:
... Soil organic matter (SOM) is of critical importance to the functioning of ecosystems because of its effects on soil nutritional quality, microbial activity and soil structure. SOM is made up of a variety of compounds ranging from chemically reactive and mobile forms to stable, recalcitrant forms. An operationally defined fraction of soil organic matter known as glomalin-related soil protein (GRSP) ...
... This study aimed to isolate and identify fungal species involved in sliced bread spoilage, and to evaluate their susceptibility to antifungal proteins of fungal origin (AFPs). Proteins include PdAfpB from Penicillium digitatum and PeAfpA, PeAfpB and PeAfpC from Penicillium expansum. Based on morphological criteria, a group of sixteen fungal isolates were selected and subsequently identified at the ...
... Once harvested, papaya fruit is prone to rapid deterioration and spoilage by microorganisms leading to food loss. The current study aimed to evaluate the effect of kojic acid (KA) treatments (2 mM and 5 mM) on the resistance of postharvest papaya against Colletotrichum brevisporum, a hazardous fungal pathogen. The results indicated that KA treatment decreased the lesion length in papayas by 30% af ...

Abstract:
... Ochratoxin A (OTA) is a fungal secondary metabolite produced by certain species of Aspergillus and Penicillium, and is generally found in contaminated grains, presenting considerable risks to human and animal health. Poor stability and insufficient miniaturization of equipment are the two main shortcomings of existing optical biosensors. Herein, we proposed a novel strategy where a magnetic metal- ...
... Intensive agricultural crop production can lead to a decline in biological soil characteristics and functions, such as soil microbial biomass and activity, carbon and nutrient cycling and soil suppressiveness, important for the sustainable production of food and feed. There is a need to understand how those soil functions can be improved by agricultural practices. In a long-term field study, we as ...
... Ochratoxin A (OTA) is a secondary fungal metabolite produced by Aspergillus and Penicillium spp. OTA contamination of food and animal feed has been attracting increasing concern in view of its toxicity, such as nephrotoxic, teratogenic, embryotoxic, genotoxic, neurotoxic, carcinogenic, and immunosuppressive effects. The widespread contamination of OTA in food and multiple toxicity of OTA have prom ...
