The aim of this research is to explore the application of natural biopolymer chitosan for the purpose of incorporating fragrance oil into automotive fabrics and its antimicrobial properties relevant to automotive interior textiles. Chitosan was selected for this study for its film forming ability and inherent antimicrobial attributes. 100% polyester automotive fabrics were used in this study, as 100% polyester is predominant fibre used for automotive interior textiles.

This history of antimicrobials is marked with impressive discoveries, the majority of which have their origin in natural products. However in this work, the antimicrobial activity of β- nitrostyrenes and related compounds of synthetic origin is reviewed and investigated with a particular focus on the influence of fluorine functionality. Various fluorinated β-methyl-β-nitrostyrene compounds were prepared, their minimum inhibition concentration in cultures of Gram positive, Gram negative and a fungus and their lipophilicity was determined.

Antimicrobial resistance is an emerging challenge for health personnel and researchers. In such scenario, alternative strategies targeting novel ways to kill or inhibit growth of microbes are need of the hour. Antimicrobial peptide can be a promising candidate to deal with this crisis. Extracellular matrix protein vitronectin (Vn) is recently being established as a bactericidal agent against certain microbes. Caprine Vn has got few structural alterations as compare to human Vn.

The binding of Thermomyces lanuginosa lipase and its mutants [TLL(S146A), TLL(W89L), TLL(W117F, W221H, W260H)] to the mixed micelles of cis-parinaric acid/ sodium taurodeoxycholate at pH 5.0 led to the quenching of the intrinsic tryptophan fluorescence emission (300–380 nm) and to a simultaneous increase in the cis-parinaric acid fluorescence emission (380–500 nm). These findings were used to characterize the Thermomyces lanuginosa lipase/cisparinaric acid interactions occurring in the presence of sodium taurodeoxycholate....
