Molecular analysis and malting quality of spring barley varieties (Hordeum vulgare L.) Valtický and Diamant.

open access: yesKvasný průmysl, 2008
With the help of all the techniques used (RAPD, SSR and AFLP), it was possible to find differences on the DNA level between the varieties Valtický and Diamant. It was not possible to differentiate the varieties related to Diamant from the other varieties

Aspergillus niger Environmental Isolates and Their Specific Diversity Through Metabolite Profiling

open access: yesFrontiers in Microbiology, 2021
We present a biological profile of 16 Aspergillus niger environmental isolates from different types of soils and solid substrates across a pH range, from an ultra-acidic (<3.5) to a very strongly alkaline (>9.0) environment.

Parasitological and molecular study of Toxocara spp. in Lumbericus terrestricus earthworms

open access: yesBulgarian Journal of Veterinary Medicine, 2020
Soil-associated invertebrates which are coprophagic are capable of acting as paratenic hosts for Toxocara species larvae eggs. The aim of the present study was to assess the role of Lumbricus terrestris earthworms as potential intermediate host for ...
