Resourcefulness of propylprodigiosin isolated from Brevundimonas olei strain RUN-D1.

A novel red-pigmented bacterium was isolated from a water sample collected at Osun River, Ede. Morphological and 16 S rRNA gene sequencing revealed that the bacterium is a strain of Brevundimonas olei, while its red pigment was identified using UV-visible, FTIR and GCMS as a derivative of propylprodigiosin. The maximum absorbance of 534 nm, the FTIR's 1344 cm peak of prodigiosin's methoxyl C-O interaction, and the molecular ions from GCMS confirmed the pigment's identity.

Chemical Composition, and Antimutagenic Activities of Ethanolic and Aqueous Extracts of Tigernut ().

Tigernut, also known as , is said to be high in nutritional and medicinal value. The purpose of this study was to determine the 's antimutagenic activity. The ethanolic and aqueous extracts of the nut were analyzed for chemical constituents, antioxidants, ultraviolet-visible, and gas chromatography-mass spectrometry using standard procedures.

Chemotherapeutic Potential of Root Extract as Antidiarrheal and In Vitro Antibacterial Activities.

Our research work was designed to investigate the curative and preventive effects of root extract against diarrhea and microorganisms. For the antibacterial experiment, the agar well diffusion method was used against standard bacteria , , and while for the assessment of antidiarrheal activity, castor oil and the magnesium sulfate-induced diarrhea method was used on albino, laboratory-bred (BALB/c) mice at a dose rate of 200 and 400 mg/kg (body weight, b.w) orally.
