AI Article Synopsis
- Two strains of cellulose-degrading microorganisms, Cochliobolus kusanoi and Aspergillus puulaauensis, were identified through DNA sequencing.
- A composite microbial system was created to enhance the breakdown of tea residues, resulting in a significant increase in soluble dietary fiber yield through mixed fermentation compared to using single strains.
- The mixed fermentation method produced dietary fiber with improved structural properties and higher adsorption capacities for various molecules, suggesting its potential in enhancing dietary fiber functionality and optimizing crop residue utilization.
Article Abstract
In our study, two high efficiency cellulose degrading strains were screened, isolated and identified as Cochliobolus kusanoi and Aspergillus puulaauensis by 18S rDNA gene sequencing. In addition, the composite microbial system was constructed to develop the synergistic effect among different strains. Under the optimum conditions, the yield of soluble dietary fiber from tea residues by mixed fermentation method (MF-SDF) dramatically increased compared to single strain fermentation. The structural analysis demonstrated that all samples possessed the representative infrared absorption peaks of polysaccharides, whereas MF-SDF revealed more loose structure, lower crystallinity and smaller molecular size. For the adsorption capacities indexes, MF-SDF also owned the highest adsorbing capacity for the water molecule, oil molecule, cholesterol molecule and nitrite ion. Overall, our data showed that mixed fermentation method could be better choices to improve the functional properties of dietary fiber, and screening of cellulose degrading strains could provide new thinkings for the study of dietary fiber modification and realize high-quality utilization of crop residues.

The gut microbiota is a crucial link between diet and cardiovascular disease (CVD). Using fecal metaproteomics, a method that concurrently captures human gut and microbiome proteins, we determined the crosstalk between gut microbiome, diet, gut health, and CVD. Traditional CVD risk factors (age, BMI, sex, blood pressure) explained < 10% of the proteome variance.

Background: Cadmium (Cd) is a very poisonous pollutant in the environment that has harmful implications on the neurological system. While high fiber intake is beneficial for mental health, it remains unknown whether the recommended basis for dietary fiber intake (DFI) (14 g/1000 kcal per day) can alleviate Cd-induced depression.
Methods: The investigation employed data from the National Health and Nutrition Examination Survey (NHANES) conducted between the years 2005 and 2020.

Astragalus polysaccharides (APS) are known for their prebiotic properties, and fermentation by probiotics is a promising strategy to enhance the prebiotic activity of polysaccharides. In this study, Lactobacillus rhamnosus was used to ferment APS, and response surface methodology was applied to optimize the fermentation parameters. The optimal conditions were determined as follows: 10.

Traditional Chinese medicine (TCM) is a treasure of China and a crucial part of traditional medicine in the world, particularly in many oriental countries. TCM is the core and basis of traditional medicine in clinical practice for numerous diseases, and performs important function in nutraceuticals and dietary supplements. However, it is extremely difficult to extract each active ingredient from TCM to elucidate the mechanism of TCM clinical efficacy due to numerous compounds in TCM, especially trace compounds.

Iron fortification compounds are of special interest to treat iron deficiency anemia, however, the dose-response effects of these fortificants on liver and renal functions have not been extensively reported in human subjects. The present study determines the effects of prebiotics and iron fortificants on liver function tests (LFTs) and renal function tests (RFTs) among women of reproductive age (WRA). A double-blind randomized controlled trial was performed for the duration of 90 days.
