Co-Occurrence of and Metabolites in Brewing Barley Monitored during Two Consecutive Years (2019-2020).

Known mycotoxins have been investigated for years. They have been included in legislation and are meticulously controlled in most cereals, cereal-related products, and raw materials of animal origin. However, there are still mycotoxins that need to be addressed by regulations and subsequently are not monitored but can still occur in relatively high concentrations.

Speleomycology of Air in Stopića Cave (Serbia).

Fungi can colonize organic matter present in subterranean sites and have a significant role as dwellers in different microniches of cave habitats. In order to analyze the content of airborne fungal propagules in different parts of "Stopića Cave," a touristic site in Serbia, air sampling was carried out in three seasons during 2020, prior to and during the onset of COVID-19 pandemic. Culturable mycobiota was identified using both microscopic techniques and ITS region/BenA gene barcoding, while multivariate analyses were employed to establish the link between fungal taxa and different environmental factors.

Early Antioxidative Response to Desiccant-Stimulated Drought Stress in Field-Grown Traditional Wheat Varieties.

Extended drought affects the production and quality of wheat ( L.), one of the world's most important food crops. Breeding for increased drought resistance is becoming increasingly important due to the rising demand for food production.

Effect of the Addition of Hulless Barley Flour on the Quality of Short-Dough Cookies.

Short-dough cookies are one of the most popular cereal-based products in the world, but usually they are considered as foods with a low nutritional value. Therefore, the aim of this study was to investigate the possibility of replacing part of the wheat flour (WF) with hulless barley flour (HLBF), in order to improve the functional properties and nutritional value of the cookies. Cookies were prepared from composite flours in the ratios HLBF:WF 0:100, 25:75, 50:50, 75:25, and 100:0.

Phenolic Acid Profiles and Antioxidant Activity of Major Cereal Crops.

Phenolic acids (PAs) are a dominant group of phenolic compounds in cereals, existing mostly bound to compounds of cell wall. In this study, a total of 25 cereal grain samples, including wheat, winter and spring barley, corn, and popcorn, were evaluated for bound PAs and antioxidant activity in a two-year field trial. The PA contents, determined by HPLC, were significantly affected by cereal type.

Distribution of β-Glucan, Phenolic Acids, and Proteins as Functional Phytonutrients of Hull-Less Barley Grain.

Two hull-less barley varieties were roller-milled, and breaks (B) and reduction flours (C), shorts, and bran were collected. Shorts, which mainly originate from endosperm cells with a smaller amount of the outer layers, had the largest yield (48.87-51.

Screening of Various Metabolites in Six Barley Varieties Grown under Natural Climatic Conditions (2016-2018).

Climatic changes influence considerably the distribution and occurrence of different secondary metabolites in cereals. The aim of this investigation was to assess the changes in metabolite prevalence observed in six different winter barley varieties over a statistically significant period of three years by linking agro-climatic conditions with metabolite concentrations in chosen samples. The results showed that temperatures and precipitation levels varied during the observed timeframe and that the multi-toxin concentrations followed the trend of changing climatic conditions depending on the variety.

Comparison of fluidized bed and ultrasonic cell-retention systems for high cell density mammalian cell culture.

Economically viable biopharmaceutical production is to a high degree dependent on high product yields and stable fermentation systems that are easy to handle. In the current study we have compared two different fermentation systems for the production of recombinant protein from CHO cells. Both systems are fully scaleable and can be used for industrial high cell density bioprocesses.

Influence of carboxymethyl dextran and ferric citrate on the adhesion of CHO cells on microcarriers.

Due to the inherent risks of animal-derived raw materials, the biopharmaceutical industry has an increasing demand for serum-free and protein-free media for industrial cell culture bioprocesses. The absence of serum often changes the characteristics of mammalian cells, especially growth, productivity, and adherence properties. This study is mainly focused on the influence of media additives on cell adherence characteristics.
