This review presents developments in the chemical processing of fermentation-derived compounds, focusing on ethanol, lactic acid, 2,3-butanediol and the acetone-butanol-ethanol mixture. We examine pathways from these products to biologically-derived drop-in fuels, polymers, as well as commodity chemicals, highlighting the role of homogeneous and heterogeneous catalysts in the development of gre...

The self-assembling of surface active antidepressant drug amitriptyline hydrochloride (AMT) has been studied to determine the micellar solution behavior in presence polar (methanol and ethanol), dipolar aprotic solvents (acetone 1,4 dioxane), salt (NaCl) water structure-breakers (urea) at 298 K using tension electrical conductivity measurements. counterion binding parameter ionization degree AM...

Though a simple daily observation, evaporation of drops is still poorly understood due to the complex nature that involves hydrodynamic effects in bulk fluids and transport phenomena at liquid-vapor interface. This paper reports on single component droplets (water, ethanol, acetone, glycerol) levitated single-axis non-resonant levitator. It was observed acetone ethanol evaporated faster than wa...

Curtisia dentata is used in African traditional medicine to treat variety of infections. C. dentata leaves were collected from Buffelskloof Nature Reserve, South Africa. The ethanol, chloroform, ethyl acetate and acetone extracts were evaluated for antimicrobial activity using micro dilution assay against Escherichia coli, Pseudomonas aeruginosa, Mycobacterium smegmatis, Mycoplasma hominis, Can...

AIMS The expression of cytochrome P4502E1 (CYP2E1) in the brain has been demonstrated in several regions, nevertheless there is a lack of specific studies on the constitutive expression and induction at the mesocorticolimbic system, the most relevant brain pathway in the context of drug addiction and alcoholism. Hence, we have performed a detailed study of the CYP2E1 expression and induction in...

Azadirachta indica is a very useful traditional medicinal plant in the sub-continent and each part of the tree has some medicinal properties. The plant is native to Asia, but has now naturalized in West Africa and is widely cultivated in Nigeria as an ornamental as well as medicinal plant. Fresh leaves of the plant were collected, dried, homogenized and extracted using 95% Ethanol, Methanol and...

Cyperus rotundus, Caesalpinia bonducella, Tinospora cordifolia, Gardenia gummifera, Ailanthus excelsa, Acacia arabica, Embelia ribes and Ventilago maderspatana from Melghat forest were screened for their antibacterial potential against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris, Salmonella typhi, Shigella flexneri, Salmonella paratyphi, Salmonella typhimuri...

The Catharanthus roseus L. plant leaf extracts were prepared by using solvents such as acetone, ethanol, and chloroform and tested against pathogenic microorganisms to determine their antimicrobial potential. Catharanthus roseus leaf extracts showed maximum antibacterial activity against all the pathogenic microorganisms. Among the solvents tested, ethanol showed maximum antibacterial activity ...

Two faba bean (Vicia faba L.) subspecies major and minor and lentil seeds grown in Algeria were separated into cotyledons and hulls. These fractions, together with their corresponding whole seeds, were extracted with two solvents, aqueous (70%) acetone and (80%) ethanol, and evaluated for antioxidant activity in relation to their phenolic contents. Acetone selectively extracted tannins from fab...

Synthesis gas (syngas) fermentation by anaerobic acetogenic bacteria employing the Wood-Ljungdahl pathway is a bioprocess for production of biofuels and biocommodities. The major fermentation products of the most relevant biocatalytic strains (Clostridium ljungdahlii, C. autoethanogenum, C. ragsdalei, and C. coskatii) are acetic acid and ethanol. A comparative metabolic and genomic analysis usi...
