Abstract

This report provides for the first time a novel environment friendly extracellular synthesis of stable silver nano-bioconjugates (SNBCs) at room temperature at pH 5.0 using Penicillium citrinum MTCC 9999 biomass. The UV-Visible spectral scan of dispersed SNBCs solution showed absorption in the region 340-450 nm due to surface plasma resonance (SPR). Typical Transmission Electron Microscopic (TEM) images showed that although two populations were present but most of them were in 20-30 nm range. Average zeta potential of SNBCs was -21 mV suggesting some biomolecules capped the nanoparticles imparting a net negative charge over it. FTIR analysis also showed that biomolecules were involved in stabilization. SNBCs showed strong antibacterial activity against both Gram positive (Bacillus subtilis) and Gram negative bacteria (Escherichia coli). SNBCs also showed strong antifungal activity as assessed against Schizosaccharomyces pombe. In the case of E. coli the minimum inhibitory concentrations (MIC) of SNBCs was 4 μg/ml while in B. subtilis it was 8 μg/ml. In the case of E. coli the minimum bactericidal concentrations (MBC) of SNBCs was 8 μg/ml while in B. subtilis it was 32 μg/ml. The SNBCs exerted its antibacterial and antifungal activity through generation of reactive oxygen species (ROS) inside the cell.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 February 2013.
All research outputs
#2,901,085
of 3,629,479 outputs
Outputs from AMB Express
#57
of 148 outputs
Outputs of similar age
#65,440
of 85,590 outputs
Outputs of similar age from AMB Express
#2
of 10 outputs
Altmetric has tracked 3,629,479 research outputs across all sources so far. This one is in the 2nd percentile – i.e., 2% of other outputs scored the same or lower than it.
So far Altmetric has tracked 148 research outputs from this source. They receive a mean Attention Score of 1.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 85,590 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 8 of them.
