Biogenic synthesis of bimetallic nanoparticles (gold -AuNp and selenium -SeNp) using inexpensive Tryptophan Enriched Banana Peel Media for the growth of marine isolate (Exiguobacterium aestuarii SBG4 MH185868). The response surface methodology is employed for optimizing production conditions. The surface plasmon resonance band showed λ max at 540 nm (AuNp) and 284 nm (SeNp). FTIR and zeta potential analysis confirmed the stability, whereas XRD spectra revealed the nature of nanoparticles obtained at optimum conditions. SEM micrographs showed nanospheres of the following size: AuN, 30 ± 5 nm and SeNp, 50 ± 5 nm. Biocompatibility of Np evaluated by the hemolytic activity showed <20% hemolysis even at highest concentrations (100 µg/ml). AuNp showed the least cytotoxicity, whereas SeNp showed considerable cytotoxicity against the breast cancer cell lines MCF -7 and MDA-MB-231. Hence, we utilized the environment-friendly growth media for the controlled synthesis of dual Np using single bacterial strain involving feasible steps in downstream processing.

“…FT-IR analysis of ethanolic and aqueous extracts of T. indica leaves revealed that functional group components of alcohols, amino acids, carboxylic acid, alkanes, alkenes, organic hydrocarbons, aryl (Aromatic ring), thiols group and ethers compounds. Correa et al [24] analyzed the aqueous leaf extract of T. indica by FT-IR and reported that the aromatic ring compounds, alkenes, amines, alcohols and alkyl halides were only present in the extract.…”

Tamarindus indica is one of the medicinal plants used in the treatment of various diseases traditionally. Aims: This study was conducted to identify the phytochemical constituents of T. indica leaf extracts. Methods: Using Fourier-transform infrared spectroscopy (FT-IR) and gas chromatography-mass spectrometry (GC-MS) to identification of bioactive compounds in extracts of T. indica. Results: The FT-IR spectrum confirmed the presence of alcohol group, alkene group, amine group, carbonates, ethers, carboxylic acid and disulfides in both extracts. A total of 22 and 38 bioactive phytochemical compounds were identified in the ethanolic and aqueous extracts of T. indica, respectively. The major bioactive compounds of the ethanolic extract of T. indica leaves were cis-Vaccenic acid, trans-13-Octadecenoic acid, Oleic Acid, Octadecanoic acid, Octadecanoic acid, 2-(2-hydroxyethoxy) ethyl ester, Eicosanoic acid and Eicosane, 1-Iodo-2-methylundecane, 10-Methylnonadecane. While the major bioactive compounds of the aqueous extract were 3-O-Methyl-d-glucose, Myo-Inositol, 4C-methyl-, Myo-Inositol, 2-C-methyl-, Propane, 2,2-dimethoxy-, 1,3-Dioxolane, Ethanol, 2-(1-methylethoxy)-, and 2-Pentanone, 4-hydroxy-4-methyl-, 2-Hexanol, 2-methyl-, Ethanamine, N-methyl.
