Potential Utilization of a Weed Prosopis
Juliflora Leaf Extract Nanoparticle
for Dye Degradation and Antibacterial
Activity
S. Sahithya and C. Krishnaveni
Abstract The present study was conducted to evaluate the silver nanoparticle
synthesized using leaf extract of Prosopis juliflora. For possible dye degradation
and antibacterial activity on Gram positive and gram-negative bacteria (Bacillus
subtilis and Pseudomonas putida). The acetone extract showed good anti-bacterial
activity against both the organisms, the inhibitory effect increased with increase in
concentration of the extract. The presence of Silver Nanoparticles in the leaf extract
was observed by reduction of silver ions into silver nanoparticles. Fourier Transform Infra-Red (FTIR) analysis was done to detect the functional groups which will
promote the antibacterial and dye degradation capabilites.
1 Introduction
Plants have served human beings as natural source for the treatments and therapies
from ancient times, amongst them medicinal herbs have gained attention because of
their wide use and less side effects. Higher plants serve as reservoirs of large number
of organic compounds that are highly beneficial as they possess curative properties
which are treated as secondary metabolites. The knowledge of chemical compounds
of a plant is very essential to identify new resources to meet the ever-increasing
demand on medicinal plants. Weed species interfere with our endeavors, such as
agriculture or animal farming, recreational pursuits, including gardening, transport,
bush walking and water sports etc. Globally, the utilization of weeds has been patchy
over the past few decades. Utilization has been recognized as an effective means of
weed management. Weeds have been used for long time as sources of food, fiber, dye,
medicines, etc. Prosopis juliflora is a shrub or a small tree belonging to the family
Fabaceae, a kind of mesquite. Its common uses include forage, firewood and environmental management (Ruto et al. 2018). But it has become an invasive weed in several
countries where it was introduced. Though it is considered as an invasive weed, it
has been used as a folk remedy for diarrhea, dysentery, flu, inflammation, measles,
