Summary
This study shows that a human intestinal bacterial biotransformation model is stable and reproducible. This model effectively transforms isoquercetin to quercetin, proving its utility for analyzing Chinese medicinal materials.
Area of Science:
- Microbiology
- Pharmacology
- Biotechnology
Background:
- Human intestinal bacteria play a crucial role in the biotransformation of xenobiotics.
- Isoquercetin, a flavonoid, undergoes significant metabolic changes in the gut.
- Developing a stable in vitro model is essential for studying these biotransformations.
Purpose of the Study:
- To assess the stability and reproducibility of a human intestinal bacterial biotransformation model.
- To evaluate the model's capacity to transform isoquercetin.
- To determine the model's suitability for analyzing bioactive compounds in traditional medicines.
Main Methods:
- Established in vitro biotransformation models using intestinal bacteria from diverse human volunteers.
- Employed standard operating procedures for model development and maintenance.
- Utilized isoquercetin as the substrate to assess transformation capabilities.
Main Results:
- All developed models successfully transformed isoquercetin into quercetin within 24 hours.
- Transformation efficiency demonstrated an increasing trend with successive culture passages.
- The model exhibited consistent performance across different volunteer-derived bacterial consortia.
Conclusions:
- The human intestinal bacterial biotransformation model is stable and yields reproducible results.
- The model's reliability supports its application in investigating chemical constituents of Chinese medicinal materials.
- This validated model facilitates in-depth studies of drug metabolism and natural product bioactivity.

01:27Microbiota of the Stomach and Small Intestine
19
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...

01:27Microbiota of the Large Intestine
16
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

01:22Introduction to the Human Microbiota
46
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...
