Bioactive prodigiosin-impregnated cellulose matrix for the removal of pathogenic bacteria from aqueous solution

Abstract

The prodigiosin impregnated column reactor (PICCR) was developed for the removal of pathogenic bacteria from water/wastewater. The impregnation of prodigiosin on cellulose matrix significantly improved the activity and stability.

Bioactive Prodigiosin Isolated from Serratia marcescens using Solid State Fermenter and its Bactericidal Activity Compared with Conventional Antibiotics

“…However, the prodigiosin containing bacterial cells were completely killed. It may due to the mechanism of action on the inhibition of cell wall biosynthesis, protein synthesis, and DNA synthesis as described by peach et al 2013 [31,32]. Moreover, the same bacterial removal pattern was observed with illuminometer ( Figure 7).…”

“…The prodigiosin and chloramphenicol solution showed 75 and 98% of bacterial cells with red colour. The red colored cell indicate, the propidium iodide stain was attached with the dead bacterial cell due to the presence of nucleic acid functional sites in the bacterial cell membrane [31]. The red colored cells indicated the dead cells because the addition of the propidium iodide was directly attached to the nucleic acid site.…”

Nanomaterials for removal of waterborne pathogens

“…Their positive surface charge and small size makes them stable in biological systems and they tend to bind with negatively charged bacterial membranes (study on S. choleraesuis, M. smegmatis, P. aeruginosa, S. typhi, and S. aureus) and causes cell leakage through membrane disruption (Qi et al, 2004;Sonawnae et al, 2012). Prodigiosin impregnated cellulose matrix has been found to remove E. coli (97.31%) and B. cereus (97.33%) (Arivizhivendhan et al, 2015).…”

Novel nanocomposite membranes from cellulose acetate and clay-silica nanowires

“…[42] Among various membranes being used in biomedical applications, cellulose based membranes offers a number of advantages especially in terms of biodegradability and environmental friendliness. [43][44][45] Cellulose or CA based membranes have been used in haemodialysis and wound dressing applications with drug release. [46] In this context, the current study offers the viability of the successful use of SiO 2 NWs similar to pure silica nanowires (without 2D units) as a reinforcement in polymer materials with low mechanical properties profiles like cellulose or CA membranes.…”
