The small-large intestine axis in hydrogen sulfide accumulation and testing of sulfate and lactate in the gut-gut axis of the intestinal environment has not been well described. Sulfate reducing bacteria (SRB) of the genus reduce sulfate to hydrogen sulfide and can be involved in ulcerative colitis development. The background of the research was to find correlations between hydrogen sulfide production under the effect of an electron acceptor (sulfate) and donor (lactate) at different concentrations and Vib-7 growth, as well as their dissimilatory sulfate reduction in the intestinal small-large intestinal environment.
Microbiological, biochemical, and biophysical methods, and statistical processing of the results (principal component and cross-correlation analyses) were used.
Vib-7 showed increased intensity of bacterial growth and hydrogen sulfide production under the following concentrations of sulfate and lactate: 17.4 mM and 35.6 mM, respectively. The study showed in what kind of intestinal environment Vib-7 grows at the highest level and produces the highest amount of hydrogen sulfide.
The optimum intestinal environment of Vib-7 can serve as a good indicator of the occurrence of inflammatory bowel diseases; meaning that these findings can be broadly used in medicine practice dealing with the monitoring and diagnosis of intestinal ailments.
硫化氢积累中的小肠-大肠轴以及肠道环境的肠-肠轴中硫酸盐和乳酸盐的检测尚未得到充分描述。该属的硫酸盐还原菌(SRB)将硫酸盐还原为硫化氢,并可能参与溃疡性结肠炎的发展。本研究的背景是寻找在不同浓度的电子受体(硫酸盐)和供体(乳酸盐)作用下硫化氢产生与Vib-7生长之间的相关性,以及它们在肠道小肠-大肠环境中的异化硫酸盐还原作用。
采用微生物学、生物化学和生物物理学方法以及结果的统计处理(主成分分析和互相关分析)。
在以下硫酸盐和乳酸盐浓度下,Vib-7的细菌生长强度和硫化氢产生增加,分别为17.4 mM和35.6 mM。该研究表明Vib-7在何种肠道环境中生长水平最高且产生的硫化氢量最多。
Vib-7的最佳肠道环境可作为炎症性肠病发生的良好指标;这意味着这些发现可广泛应用于医学实践中肠道疾病的监测和诊断。
