“…As a food with starch, B. gymnorrhiza fruit (BGF) are sliced, soaked to flush out the tannins and then ground to a paste, which can be an ingredient for pastry (Bandaranayake and Marshes, 1998). In addition, BGF has been commonly used to treat chronic diarrhea for many years (Mahmud et al, 2017), which are also known as ulcerative colitis according to TCM theory. However, current investigations have been mainly focused on its anticancer and anti-diabetic effects, seldom endeavor has been dedicated to illuminating its traditional application like diarrhea.…”

homeostasis. BGF possessed protective effect against DSS-induced colitis. The potential mechanism of BGF may involve the amelioration of inflammatory and oxidative status, activation of Keap1/Nrf2 signaling pathway, and maintenance of micro-ecological balance of the host. This study provides experimental evidence for the traditional application of BGF in the treatment of diarrhea, and indicates that BGF may be a promising candidate against colitis.

“…A recent study isolated 28 entophytic bacteria from the leaves and roots of Cenchrus fungigraminus ( Jing et al, 2022 ). Similarly, 24 endophytes were isolated from different parts of Bruguiera gymnorhiza ( Mahmud et al, 2017 ). However, the number of endophytic bacteria in any plant species is very high, never so far isolated more than 200 bacterial species.…”

IntroductionEndophytes and their host plants have co-evolved for a very long time. This relationship has led to the general recognition of endophytes as a particular class of microbial resources. R. pseudoacacia ‘Hongsen’ is drought- and barren-resistant species that can be grown in both the north and south of China, efficiently addresses the ecological issues caused by China’s ‘southern eucalyptus and northern poplar. Up to date, cultured-dependent studies are available for the R. pseudoacacia nitrogen-fixing and other endophytes. Therefore, the present research studied the R. pseudoacacia ‘Hongsen,’ microbiome in detail by high-throughput sequencing and culture dependant.MethodsThis study examined microbial species and functional diversity in Robinia pseudoacacia ‘Hongsen’ using culture-dependent (isolation) and culture-independent techniques.ResultsA total of 210 isolates were isolated from R. pseudoacacia ‘Hongsen.’ These isolates were clustered into 16 groups by the In Situ PCR (IS-PCR) fingerprinting patterns. 16S rRNA gene sequence analysis of the representative strain of each group revealed that these groups belonged to 16 species of 8 genera, demonstrating the diversity of endophytes in R. pseudoacacia ‘Hongsen’. ’Bacillus is the most prevalent genus among all the endophytic bacteria. High-throughput sequencing of endophytic bacteria from R. pseudoacacia ‘Hongsen’ of the plant and the rhizosphere soil bacteria showed that the bacterial populations of soil near the root, leaf, and rhizosphere differed significantly. The microbial abundance decreased in the endophytes as compared to the rhizosphere. We observed a similar community structure of roots and leaves. With and without root nodules, Mesorhizobium sp. was significantly different in R. pseudoacacia ‘Hongsen’ plant.DiscussionIt was predicted that R. pseudoacacia ‘Hongsen’ plant endophytic bacteria would play a significant role in the metabolic process, such as carbohydrate metabolism, amino acid metabolism, membrane transport, and energy metabolism.

Antibiotic resistance has become one of the inevitable barrier in aquaculture disease management. Herbal drugs has evolved to be the novel ways of combating drug resistant pathogens. In the current investigation, leaf extracts of mangrove plant, Acanthus ilicifolius were assessed for in vitro studies, among the selected four extracts, methanol extract has expressed highest antibacterial activity against P .aeruginosa (4 ± 0.3 mm), A. hydrophila (5.9 ± 0.5 mm), S. aureus (3.5 ± 0.7 mm) and B. subtilis (2.9 ± 0.5 mm) and antioxidant activity, DPPH (81.3 ± 1.0 AAEµg/ml) and FRAP (139.1 ± 1.5 AAEµg/ml).TPC and TFC were higher in the methanolic extract and has exhibited positive correlation with both DPPH and FRAP assays. Considering the in vitro efficiency, methanol extract was purified successively by column and thin layer chromatography and characterisation by GC–MS unveiled the presence of 2-Propanethiol, Trimethylphosphine, Pentanoyl chloride, Dimethylhydroxymethylphosphine and Propanedinitrile, ethylidene. A. hydrophila infected L. rohita fingerlings has survival percentage 81% and 94% in extract treated groups over 0% in negative control and 71% in positive control.
