📃Scientific paper: Nutrient availability of roughages in isocaloric and isonitrogenous diets alters the bacterial networks in the whole gastrointestinal tract of Hu sheep Abstract: Background The nutrient availability of roughages could affect the dietary utilization efficiency of ruminants even in isocaloric and isonitrogenous diets. Here, we analyzed the bacterial composition and their metabolic pathways in the gastrointestinal tracts (GITs) of Hu sheep fed with wheat straw (WS) instead of alfalfa (AL) in isocaloric and isonitrogenous diets, trying to explore the reasons from the perspective of GITs bacterial network structure changes. Results We employed 16S rRNA gene sequencing in combination with the Kruskal–Wallis test, Spearman correlation analysis, and other statistical methods to describe the microbiota composition in the GITs of Hu sheep. The results showed after the roughage was replaced from AL to WS, the most positive response occurred in the rumen microbiota, resulting in a more obvious microbiological and functional redundancy phenomenon. Whereas extended biogeographic studies of the GITs bacterial community found opposite results for the hindgut microbiota and metabolism networks compared to the forestomach. The abundance of fiber-degrading bacteria such as Prevotella , Oscillospiraceae NK4A214 group , and Treponema was significantly increased in GITs, but low-efficiency crude fiber degradation inhibited energy use efficiency, the pentose phosphate pathway, gluconeogenesis, and volatile acid synthesis. In addition, dietary shifting from AL to WS decreased the abundance of beneficial bacteria such as the Lachnospiraceae NK3A20 gro...

🖥️ Although #bioinformatics research focuses mostly on disease sciences, we rarely reflect on how these technologies can also influence everyday elements of our daily lives. The article by Francielly Soares Oliveira, Rafaela Da Silva Rodrigues, Antonio Fernandes de Carvalho and Luis Nero presents a #genomic characterization of Pediococcus pentosaceus ST65ACC, a bacteriocinogenic strain isolated from Brazilian artisanal cheese. This study, published in Probiotics and Antimicrobial Proteins, delves into the biotechnological characteristics of this strain, its probiotic potential and its applicability in the food industry. Metabolic pathways specialized in carbohydrate metabolism were identified and genes related to resistance to certain acids, suggesting a tolerance to gastrointestinal environments. It is relevant to note that the strain was considered safe for human consumption. 🦠🧀 In a world where awareness of what we consume has become crucial, and where it has been proven that the gut #microbiota plays a fundamental role in human health, Foods containing beneficial micro-organisms present a fascinating opportunity for research. These products can not only improve our nutrition, but also strengthen our immune system and prevent diseases. Bioinformatics, with its ability to analyze large volumes of data at the genetic and molecular level, has revolutionised our understanding of these micro-organisms. It allows us to identify the specific properties of strains present in food, such as their probiotic potential, fermentation capacity, resistance to gastrointestinal conditions and, most importantly, their safety for human consumption.

Enhancing butyrate production would be a great feature for any potential feed additive targeting the intestinal microbiome. While not the most abundant VFA in the gut, butyrate became the most desirable one due to its numerous benefits for intestinal health. However, examining butyrate production in the gut is not as easy as one might expect. 📊 As a first step, we can use the QuantiBiom™ panel to assess butyrate content in the lumen: data on relative abundance of individual SCFA in the intestinal digesta indicate the activity of fermentation pathways for each end product including butyrate. The challenge lies in the rapid absorption of butyrate by epithelial cells. Actually, if we observe a significant spike in butyrate content in our samples, we should rather ask, why butyrate is not being absorbed. QuantiBiom™ offers a snapshot illustrating the dynamic balance between bacterial production and host consumption of butyrate. 🦠 Should our next step involve scrutinizing the microbes responsible for butyrate production? We know the good guys by names, don’t we? Well, at a higher taxonomic level, all butyrate producers fall into four families: Lachnospiraceae, Ruminococcaceae, Rikenellaceae and Clostridium sensu stricto. However, these bacterial groups also contain non-butyrate producers. So, quantitative analysis of the representatives of these families cannot be used to accurately measure butyrate producers. 🧬That’s why we had to go a more sophisticated way with our EpiHealth™ panel. We focused on the genes coding the enzymes indispensable in butyrate production. At the intersection of two main metabolic pathways, we find pyruvate. To convert pyruvate further, bacteria would mainly use one of the two enzymes: butyrate kinase (BUK) and butyryl-CoA – acetate transferase (BUT). Regardless of their taxonomic position, all common butyrate producers carry a gene for one of these enzymes. The higher the total number of BUT and BUK genes, the greater the potential of the resident bacteria to produce butyrate. Our primary challenge in developing these analytics was defining a relevant set of assays for key animal species due to several gene variants coding for BUK and BUT enzymes. We shaped our know how into the EpiHealth™ panel crafted to evaluate the potential of butyrate production. With EpiHealth™ we can evaluate the impact of the feed additive tested on the ability of intestinal microbiota to produce butyrate. So, you can start with a snapshot provided by QuantiBiom™ and get a broader picture with EpiHealth™.

It is so nice to see this article on immune responses of the novel microbial protein source, P. variotii, published by our PhD student Dominic Duncan Mensah #Foodsofnorway #aquaculture #feedingthefuture #salmonfeed #Nordforsk
It is with pleasure to share the first publication of my PhD under the NordicFeed project funded by NordForsk and the Centre for Research-based Innovation (Foods of Norway). Here we did a physical characterization, determined the glucan content and the immuno-stimulatory potential of an interesting microbial ingredient Paecilomyces variotii (PEKILO) on in vitro Atlantic salmon models. The results indicate that beyond the impressive nutritional value, P. variotii has functional properties relevant to the health of salmonids. https://lnkd.in/gzG5aBWJ

Nice overview of "omics" approach to enhance the process of identifying novel probiotic strains published by Scientific Committee at International Probiotics Association. Great work from my colleagues Mehreen Anjum & Arthur Ouwehand. " The integration of “omics” with in vivo studies may lead to selection of probiotics whose mode of action is well known, and which can then be administered for the appropriate health benefit." #Omics #Probiotics #IFF #WeAreIFF #InternationProbioticsAssociation
All Probiotics are Equal, but Some are More Equal Than Others

Could Targeting Genetics Reduce Our Cravings for Sugary Foods? A new study has revealed how genetic variations in the SI gene, which affects sucrose digestion, influence dietary preferences and intake of sugary foods. Researchers found that individuals with limited sucrose-digesting ability, due to specific genetic variations, showed reduced sugar cravings and consumption. This discovery opens up the potential to develop targeted treatments to reduce sugar intake on a population level, potentially reducing the incidence of obesity and type 2 diabetes.

Cutting Back on One Amino Acid Just Found to Increase Lifespan by 33% Recent research has shown that reducing intake of the essential amino acid isoleucine can slow aging and even extend lifespan, raising questions about whether similar effects might be achieved in humans. Isoleucine, which we get from foods like eggs, meat, dairy, and soy, is crucial for building proteins, but too much of it may negatively impact metabolic health. In the study, a group of genetically diverse mice was placed on three different diets: a control diet with 20 amino acids, a diet with a general reduction of all amino acids, and a diet where only isoleucine was reduced. Mice on the low-isoleucine diet lived longer and experienced improved health in areas such as muscle strength, endurance, and blood sugar control. Males had a 33% lifespan increase, while females saw a 7% increase. These mice also stayed leaner despite eating more calories, burning energy more efficiently without increased activity. Researchers are hopeful these findings could be applied to humans, potentially leading to diets or drugs that could delay aging. However, translating these results is complex due to the intricate nature of human diets, and more studies are needed to understand how isoleucine restriction might work in people. #MedicalLaboratoryTechnology #Microbiology #Phlebotomy #LaboratoryTesting #DiagnosticTesting #HealthcareProfessional #MedicalTesting #ClinicalLaboratory #BiomedicalScience #HealthcareIndustry #MedicalScience #LaboratoryMedicine #ClinicalMicrobiology #InfectionControl #PhlebotomyTechnician #MedicalLabTechnician #MicrobiologyLab #ClinicalLab #HealthcareCareer #MedicalCareer #ScienceCareer #COVID19Testing #Virology #Bacteriology #Parasitology #MolecularDiagnosis #GeneticTesting #Cytology #Histopathology #Immunology #Serology
