Effect of replacing gluten-free cereal flours with Gryllus bimaculatus powder on pasting and microstructural properties Open
Gryllus bimaculatus powder can be a sustainable source of animal protein and is a suitable ingredient for enriching gluten-free products. Enriching gluten-free flours with edible insect powder can impact the viscometric behavior of blends …

Pressure-assisted isolation of micro- and nanoplastics from food of animal origin with special emphasis on seafood Open
Recent studies have indicated the presence of micro- and nanoplastics in food of animal origin. To address the concerns regarding human dietary plastic uptake, extensive monitoring using validated analytical methods is required. However, a…

Surface wax in the ancestral grapevine Vitis sylvestris correlate with partial resistance to Powdery Mildew Open
Background Powdery Mildew of Grapevine belongs to the major diseases in viticulture and requires intensive use of fungicides. Genetic introgression of resistance factors from wild grapes from North America and, recently, China, has been su…

Rathayibacter rubneri sp. nov. isolated from Allium cepa var. Rijnsburger, an onion landrace Open
The novel, aerobic, Gram-stain-positive, rod-shaped bacterial strain, ZW T2_19 T , was isolated from an onion sample ( Allium cepa var. Rijnsburger). Analyses of the 16S rRNA gene sequence revealed that ZW T2_19 T represented a member of t…

Rapeseed Oil Based Oleogels for the Improvement of the Fatty Acid Profile Using Cookies as an Example Open
In this study rapeseed oil based oleogels with sunflower wax, ethyl cellulose, monoacylglycerols, or mixtures of it as oleogelators are characterized in comparison to conventional bakery margarines or partially hydrogenated peanut fat with…

An Attempt to Relate Oleogel Properties to Wax Ester Chemical Structures Open
Wax esters are considered to have a dominant contribution in the gelling properties of wax-based oleogels. To understand their gelling behavior, oleogels of seven different wax esters (total carbon number from 30 to 46; c = 10% [m/m]) in m…

Pseudomonas rustica sp. nov., isolated from bulk tank raw milk at a German dairy farm Open
Here we present the description of a novel Pseudomonas species, designated Pseudomonas rustica sp. nov., which was isolated from raw milk samples obtained from Germany. Results of initial 16S rRNA gene sequence analysis assigned the strain…

Determination of the Transport Efficiency in spICP-MS Analysis Using Conventional Sample Introduction Systems: An Interlaboratory Comparison Study Open
In single particle inductively coupled plasma mass spectrometry (spICP-MS), the transport efficiency is fundamental for the correct determination of both particle number concentration and size. In the present study, transport efficiency wa…

Adlercreutzia rubneri sp. nov., a resveratrol-metabolizing bacterium isolated from human faeces and emended description of the genus Adlercreutzia Open
The novel, anaerobic, Gram-positive, rod-shaped bacterial strain, ResAG-91 T , was isolated from a faecal sample of a male human volunteer. Analysis of the 16S rRNA gene sequence revealed that strain ResAG-91 T showed high similarity to th…

Characterization of Oleogels Based on Waxes and Their Hydrolyzates Open
In this paper, the structuring of liquid oils, also known as oleogelation, is systematically investigated for the first time using a quasi‐quaternary mixing system approach. Native waxes with different quantities of wax esters (WE), n ‐alk…

Intercellular communication is required for trap formation in the nematode-trapping fungus Duddingtonia flagrans Open
Nematode-trapping fungi (NTF) are a large and diverse group of fungi, which may switch from a saprotrophic to a predatory lifestyle if nematodes are present. Different fungi have developed different trapping devices, ranging from adhesive …
