Uncovering mechanisms of greengage wine fermentation against acidic stress via genomic, transcriptomic, and metabolic analyses of Saccharomyces cerevisiae.

Appl Microbiol Biotechnol 2020 Jul 10. Epub 2020 Jul 10.

The Key Laboratory of Industrial Biotechnology, Ministry of Education, Jiangnan University, Wuxi, 214122, Jiangsu, China.

Acid stress is one of the most common adverse conditions during fermentation of fruit wines, and the acid tolerance of yeasts is, therefore, critical for fruit wine production. However, the biological mechanism underlying the acquired tolerance of yeasts against acid stress is poorly understood. We have previously obtained an evolved Saccharomyces cerevisiae strain ET008-c54 with increased tolerance against acid stress, and potentially, it serves as a promising yeast strain for greengage wine fermentation.

Molecular and in vitro assessment of some probiotic characteristics of amylolytic strains from Bulgarian fermented products.

Eng Life Sci 2018 Nov 13;18(11):820-830. Epub 2018 Jun 13.

Department of Biotechnology University of Food Technologies Plovdiv Bulgaria.

In the recent years, consumers' interest in healthy diet opened a new field for functional food development through combining the valuable composition of cereals and the health-promoting properties of lactic acid bacteria (LAB). LAB with amylolytic properties can assimilate starch in a single-step process and could be successfully applied as starter cultures offering an efficient nutritional conversion of cereal matrices. The probiotic potential of amylolytic LAB has not been investigated so far, therefore the present study focused on the molecular screening and in vitro tests of five amylolytic strains to assess their tolerance to high acid and bile salts concentrations and antibiotic resistance as basic characteristics required for probiotic strains selection.

Artificial neural network for bioprocess monitoring based on fluorescence measurements: Training without offline measurements.

Eng Life Sci 2017 Aug 12;17(8):874-880. Epub 2017 Jun 12.

Department of Process Analytics and Cereal Science Institute of Food Science and Biotechnology University of Hohenheim Stuttgart Germany.

The feasibility of using a feed-forward neural network in combination with 2D fluorescence spectroscopy to monitor the state of fermentation was investigated. The main point is that for the backpropagation training of the neural network, no offline measurement value was used, which is the ordinary approach. Instead, a theoretical model of the process has been applied to simulate the process state (biomass, glucose, and ethanol concentration) at any given time. Read More

Bicistronic expression strategy for high-level expression of recombinant proteins in .

Eng Life Sci 2017 Oct 14;17(10):1118-1125. Epub 2017 Aug 14.

National Engineering Laboratory for Cereal Fermentation Technology Jiangnan University Wuxi P. R. China.

Directly using the promoter associated with 5'-untranslated region of a high-protein-abundance gene from the genome may cause low expression activity of an expression system. A bicistronic expression part containing the short 5' coding sequence of the source gene and an embedded Shine-Dalgarno sequence can cause higher expression levels of the recombinant gene in a bicistronic cassette. Here, we evaluated two methods to construct expression parts and exploited genomic sequence sources to provide specific functional sequences to complete the expression system. Read More

Short Communication: Assessment of the vasoactive effects of the (S)-epimers of ergot alkaloids in vitro.

J Anim Sci 2020 Jul 6. Epub 2020 Jul 6.

Department of Veterinary Pathology, Western College of Veterinary Medicine, University of Saskatchewan, Saskatoon, Canada.

Ergot alkaloids are produced by the fungus Claviceps purpurea and their levels are carefully monitored in animal and human diets due to their harmful effects and widespread contamination of cereal crops. Ergot alkaloids exist in two forms known as the (R) and (S)-epimer with only the former being monitored in diets in North America. The (S)-epimers of ergot alkaloids are thought to be biologically inactive and, therefore, harmless. Read More

Overuse of Non-caloric Sweeteners in Foods and Beverages in Chile: A Threat to Consumers' Free Choice?

Front Nutr 2020 17;7:68. Epub 2020 Jun 17.

Department of Nutrition, Faculty of Medicine, University of Chile, Santiago, Chile.

The prevalence of obesity among Chilean adults and children is one of the highest worldwide. To fight the constant increase of non-communicable diseases and the growing sales of sugar-sweetened beverages, the Chilean government recently enacted a new Law of Food Labeling and Advertising imposing the application of front-of-package warning labels in foodstuffs whose composition exceeds limits for critical nutrients including sugar. Accordingly, food companies have been reformulating their products, incorporating non-caloric sweeteners (NCSs) in partial or total replacement of sucrose. Read More

Calcium l-methylfolate as a source of folate added for nutritional purposes to infant and follow-on formula, baby food and processed cereal-based food.

EFSA J 2020 Jan 17;18(1):e05947. Epub 2020 Jan 17.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on the extension of use of calcium l-methylfolate to be used as a source of folate added for nutritional purposes to infant and follow-on formula, baby food and processed cereal-based food pursuant to Regulation (EU) 609/2013. In 2004, EFSA assessed the use of calcium l-methylfolate as a source of folate in foods for particular nutritional uses, food supplements and foods intended for the general population. The new alternative synthetic step proposed to produce the nutrient source, using platinum as a catalyst, did not raise any safety concern and the production process was found to consistently yield a product in line with the proposed specifications.

Modification of the temporary maximum residue level for mepiquat in oyster mushrooms.

EFSA J 2019 Jul 31;17(7):e05744. Epub 2019 Jul 31.

In accordance with Article 6 of Regulation (EC) No 396/2005, Finland, hereafter referred to as the evaluating Member State (EMS), received an application from BASF SE to modify the temporary maximum residue level (MRL) for the active substance mepiquat in cultivated fungi based on monitoring data. Mepiquat residues in mushrooms do not result from the use of the active substance on mushrooms, but from the uptake of residues via the growth substrate composed of cereal straw that has been treated with mepiquat. Based on a total of 74 samples on oyster mushrooms, three different MRL proposals were derived. Read More
