Soybean oligosaccharides combined with probiotics reduce faecal odour compound content by improving intestinal microbiota in pigs was written by Du, Lei;Qiu, Xiaoyu;Zhu, Siyuan;Liu, Jingbo;Wang, Jing;Wang, Qi;Liu, Zuohua;Yang, Feiyun;Yun, Tingting;Qi, Renli. And the article was included in Journal of Animal Physiology and Animal Nutrition.Category: indole-building-block This article mentions the following:

As a potential prebiotic, soybean oligosaccharides (SBOS) can improve animal health by modulating gut microbiota. The aim of this study was to investigate the different effects of supplementing SBOS and supplementing SBOS plus probiotic on the growth and health of pigs. Three groups of growing pigs (n = 12) were fed with basal diet (Control), basal diet + 0.5% SBOS (SBOS), or basal diet +0.5% SBOS + 0.1% compound probiotics (SOP) for 42 days. Results showed that SBOS and SOP treatments had pos. effects on the pigs in the experiment, and the latter was more effective. Compared with the control pigs, the average daily gain of SBOS group and SOP group slightly increased, SOP significantly increased the serum levels of growth hormone and thyroid hormone T3. Importantly, serum concentrations of Ig (IgA, IgG and IgM), total antioxidant capacity and superoxide dismutase in both treatments were increased significantly, SOP group most. Moreover, the faecal odor compounds of pigs, especially skatole, were significantly reduced by the treatments. Addnl., SOP significantly increased the diversity and richness of the faecal microbiota, both the treatments increased genera of norank_f_Muribaculaceae and Ruminococcaceae but reduced Lactobacillus. Correlation anal. indicated that Lactobacillus was significantly pos. correlated with odor compounds, while Ruminococcaceae was the opposite. Conclusively, synbiotics combined with SBOS and probiotics had stronger promotion effects on the growth and health of pigs. In the experiment, the researchers used many compounds, for example, 3-Methyl-1H-indole (cas: 83-34-1Category: indole-building-block).

Tryptophan derived natural marine alkaloids and synthetic derivatives as promising antimicrobial agents

Antimicrobial resistance has become a major threat to public health worldwide, as pathogenic microorganisms are finding ways to evade all known antimicrobials. Therefore, the demand for new and effective antimicrobial agents is also increasing. Natural products have always played an important role in drug discovery, either by themselves or as inspiration for synthetic compounds. The marine environment is a rich source of bioactive metabolites, and among them, tryptophan-derived alkaloids stand out for their abundance and by displaying a variety of biological activities, with antimicrobial properties being among the most significant. This review aims to reveal the potential of marine alkaloids derived from tryptophan as antimicrobial agents. Relevant examples of these compounds and their synthetic analogues reported in the last decades are presented and discussed in detail, with their mechanism of action and synthetic approaches whenever relevant. Several tryptophan-derived marine alkaloids have shown potent and promising antimicrobial activities, whether against bacteria, fungi, or virus. Synthetic approaches to many of the compounds have been developed and recent methodologies are proving to be efficient. Even though most of the studies regarding the antimicrobial activity are still preliminary, this class of compounds has proven to be worth of further investigation and may provide useful lead compounds for the development of antimicrobial agents. Overall, marine alkaloids derived from tryptophan are revealed as a valuable class of antimicrobials and molecular modifications in order to reduce the toxicity of these compounds and additional studies regarding their mechanism of action are interesting topics to explore in the future.

Identification of Genetic Variants via Bacterial Respiration Gas Analysis

Indole is a signal molecule derived from the conversion of tryptophan, and it is present in bacterial respiratory gas. Besides influencing bacterial growth, indole exhibits effects on human health, including a positive effect on inflammation and protection against pathogens. However, a high fecal indole concentration (FIC) can suggest an unbalanced gut flora or the presence of certain pathogens. To analyze the indole produced by bacteria, its collection and detection is required. Traditional methods usually require centrifugation of liquid bacterial culture medium and subsequent extraction of indole from the medium or partial purification of indole from fecal samples (e.g., by distillation or extraction). In this study, we demonstrate the possibility of identifying gas contents directly from bacteria, and we distinguish the difference in species and their genetics without the need to centrifuge or extract. Using an absorbent sheet placed above a liquid culture, we were able to collect gas content directly from bacteria. Gas chromatography-mass spectrometry (GC-MS) was used for the analysis. The GC-MS results showed a clear peak attributed to indole for wild-type Escherichia coli cells (MG1655 and MC4100 strains), whereas the indole peak was absent in the chromatograms of cells where proteins, part of the indole production pathway from tryptophan (TnaA and TnaB), were not expressed (by using tnaAB-deleted cells). The indole observed was measured to be present in a low nmol-range. This method can distinguish whether the bacterial genome contains the tnaAB gene or not and can be used to collect gas compounds from bacterial cultures quickly and easily. This method is useful for other goals and future research, such as for measurements in restrooms, for food-handling facilities, and for various applications in medical settings.
