Physiological behavior of newly isolated Bacterium CB1 and Stenotrophomonas maltophilia strain CB2 on Chrysene, Pyrene, Naphthalene and Fluoranthene

The biodegradability of some polycyclic aromatic hydrocarbons were studied in liquid culture media using bacterial strains (Bacterium CB1 and Stenotrophomonas maltophilia strain CB2) isolated from a former industrial site contaminated with organic and inorganic contaminants. The enrichment experiment was done with chrysene. The partial 16S rRNA gene analyses of Bacterium CB-1 possessed 100% similarity to an uncultured bacterium clone nbt020a while Stenotrophomonas maltophilia strain CB2 had 99% similarity to Paenibacillus sp. Y412MC10. Bacterium CB1 and Stenotrophomonas maltophilia strain CB2 degraded naphthalene between the range of 27% and 42%, chrysene 47% and 12%, fluoranthene 5% and 16%, pyrene 12% and 17% respectively. The strains utilized the test compounds as sole source of carbon and energy. As anticipated, the controls (abiotic and killed) losses were insignificant. The residual PAH obtained in some cases correlated to an increase in cell number indicating that our strains were responsible for the degradation

Phytochemical and antimycobacterial analysis of aqueous and ethanolic extracts of Annona muricata Linn (Soursop)

Against the backdrop evidenced in the threat Tuberculosis poses to developing economies, especially its prevalence among people in their productive (15-45) years; this preliminary study examined the phytochemical constituents and antimycobacterial effect of four (4) aqueous and ethanolic extracts from the fruit skin (epicarp) and leaf of Annona muricata Linn

Ethnomedicinal uses, phytochemistry, pharmacological activities and toxicological effects of Mimosa pudica- A review

Introduction: Mimosa pudica L. is a creeping herbaceous ornamental plant belonging to the Mimosaceae family. It is used in ethnomedicine to prevent or treat various illnesses like diarrhoea, dysentery, diabetes, alopecia, cancer and urinary tract infection. This study extensively reviewed the phytochemicals and pharmacological activities of M. Pudica. Method: The materials used in this study were obtained from the following databases: ScienceDirect, PubMed, Wiley, Springer and google scholar using relevant keywords. Only papers in the English language between January 2001 and December 2022 were included. Results: In vivo and in vitro studies revealed that M. pudica and its bioactive components possess numerous pharmacological activities such as antioxidant, antimicrobial, wound healing, anxiolytic, anthelminthic, antiophidian, hepatoprotective, antimalarial, anti-inflammatory, antidiabetic and anticancer activities. These numerous pharmacological activities may be attributed to various bioactive compounds in M. pudica. Conclusion: This study revealed that M. pudica and its numerous bioactive compounds have a strong therapeutic effect against various diseases, including life-threatening diseases such as cancer and diabetes. However, despite the widespread therapeutic potential of M. pudica, no clinical trial and quality control studies exist in the literature. Therefore, clinical trials and quality control studies are recommended to establish safe and effective doses for the prevention and treatment of diseases
