Project description:From a long time ago, supplementation of fermented enzyme foods could have worked health effects on the body in the east nevertheless, only a few studies reported functions of them such as weight loss and metabolic syndrome. Thus, it is necessary to be verified whether supplementation of fermented enzyme foods can act in the body as a functional material. Therefore, we investigated the anti-obesity effects of fermented mixed grain with digestive enzymes (FMG) in high-fat diet induced mice. Sixty C57BL/6J mice were divided into six dietary groups and fed a normal diet (ND), a high-fat diet (HFD), Bacilus Coagulans group, steamed grain group, low-dose fermented mixed grain group(L-FMG), high-dose fermented mixed grain group (H-FMG) supplement for 12 weeks. After sacrificing, body weight and body fat mass in H-FMG group were significantly decreased compared to HFD group with a simultaneous decrease in plasma lipids. Also, H-FMG significantly decreased the blood glucose and improved the glucose tolerance compared to HFD group. Moreover high-dose FMG supplementation dramatically decreased the levels of inflammatory cytokines which secreted from adipocyte. Taken together, our findings suggest that H-FMG ameliorate high fat-diet induced obesity and its complication and could be used as a potential preventive agent for obesity.
Project description:To study the characteristics of proteins in Chinese Chixiang-flavor Baijiu fermentation, a label-free quantitative proteomics approach was established to identify proteins in Jiuqu starter and fermented grains.
Project description:Using high-throughput RNA sequencing, we developed a spatiotemporal transcriptome atlas for seed development of eight maize inbred lines based on 144 samples from the middle to late stages of grain development. A total of 26,747 genes with FPKM value more than 1 at least one sample were found to be involved in programming grain development. Global comparisons of genes expression highlighted the fundamental transcriptomic reprogramming and the phases of development. Coexpression analysis provided further insight into the dynamic reprogramming of the transcriptome by revealing functional transitions during maturation. Combined with grain moisture content and grain dehydration rate of different developmental time points of eight maize inbred lines, we captured a large number of genes related to grain moisture content and grain dehydration rate, which should help elucidate key mechanisms and regulatory networks that underlie grain dehydration during maize grain development. These results provide a comprehensive understanding of which biological processes are involved in the regulation of moisture variety of maize grain, the general principles of which provide a new perspective on improving maize grain dehydration characteristics. Meanwhile, this study provides a valuable resource for understanding the genetic regulation of maize grain development.
Project description:The increasing aquaculture production volumes have caused an escalating demand for alternative protein feed ingredients. Agro-industrial by-products such as sunflower meal are relatively abundant and cheap, but the inclusion levels are limited due to the presence of antinutritional factors and fiber. Solid state fermentation is a processing method with the aim of reducing the content of fiber and antinutritional factors and improving nutritional value in plant protein raw materials. In this study, Atlantic salmon (Salmo salar) at two commercial-like fish farms were fed diets containing 5% non-fermented sunflower meal (as a control diet) and two experimental diets with 5% or 10% fermented sunflower meal. The field trial lasted for eight and 11 months in a coastal and fjord location, respectively with the aim of comparing the effect of fermented diets on growth performance, gut microbiota, distal intestine histology and gene expression of Atlantic salmon under different environmental conditions. The findings revealed that diets with fermented sunflower meal sustained growth performance, improved intestinal health by reducing the prevalence of prominent inflammation and ectopic goblet cells and promoted gut lactic acid bacteria Lactiplantibacillus and Lactobaccilaceae after long-term feeding. Our results suggest that fermented sunflower meal is suitable as a protein source for Atlantic salmon when included at a level of up to 10% in the diet.
Project description:Gene expression profile was studied to complement fine mapping studies. Genes co-located in the previously reported three aroma QTLs viz. qaro3.1, qaro4.1 and qaro8.1 were identified. Microarrays were used to study gene expression profile to reduce the number of up- and down regulated genes co-located within the reported aroma QTLs. These genes are the most suitable candidates for further validation studies and development of molecular markers to assist in Marker assisted Breeding for the development of new improved fragrant rice varieties. Six extreme aromatic RILs and six extreme non-aromatic RILs were identified on the basis of their sensory aroma scores. The RILs were pooled together to make two different bulk groups: aromatic bulk (VA) and non-aromatic bulk (VN). The two parents, Pusa 1121, the aromatic parent (VPA) and Pusa 1342, the non-aromatic parent (VRN) were also taken as two groups. RNA was isolated from fresh leaves after about 20-25 days of transplanting seedlings into experimental field, stage at which grain aroma develops. Four biological replicates (1-4) for each group were taken making a total of 16 samples.
Project description:Purpose:The purpose of this study is to explore the transcriptome analysis of the heterosis of the grain type and grain weight of the super rice WFYT025 hybrid combination at the grain filling stage.
Project description:During fermentation Saccharomyces yeast produces various aroma-active metabolites determining the different characteristics of aroma and taste in fermented beverages. Amino acid utilization by yeast during brewer´s wort fermentation is seen as linked to flavour profile. To better understand the relationship between the biosynthesis of aroma relevant metabolites and the importance of amino acids, DNA microarrays were performed for Saccharomyces cerevisiae strain S81 and Saccharomyces pastorianus var. carlsbergensis strain S23, respectively. Thereby, changes in transcription of genes were measured, which are associated with amino acid assimilation and its derived aroma-active compounds during fermentation.
