Background: The traditional Indian medicine 'Siddha' uses metals, metalloids and minerals including toxic ones with no proven toxicity. Thalagak karuppu (TK) is remarkably stable over a century and used for treating Suram (Fever), Kaasam (Cough), Elai (Tuberculosis) and Eraippu Erumal (Bronchial Asthma). Objective: The present study addresses el...
Article
Bioinspiration through biological nanomachines and their assemblies at molecular level provide guiding principles to build nanoscale functional devices. The rapid advances in the biosynthesis of nanomaterials, including hybrid nanomaterials and their applications are reviewed. Biological synthesis of nanostructures using whole organism as well as b...
Article
Tannin acyl hydrolase (tannase) production by Lactobacillus plantarum MTCC1407 was studied in submerged and solid-state fermentation process. Sequential optimization strategy using Plackett–Burman screening and response surface methodology was adopted to optimize the submerged fermentation process. Eight medium components were evaluated initially b...
Article
Large number of papers has been published recently on the eleventh group metallic elements such as Ag, Au and Cu. Our study was focused on biosynthesis of silver nanoparticles, their morphology, reactivity and stability. We were interested to check these properties in two different samples, S1 and S2, respectively. The biosynthesis of silver nanopa...

Production of tannase and microbial biomass by Lactobacillus plantarum MTCC 1407 was studied in submerged batch fermentation. The tannase production was performed in different media compositions maintaining the fermentation conditions constant at 30°C, initial pH 5.5 and agitation speed at 120 rpm. Maximum tannase activity of 5.22 U mL-l was obtain...

The biological process with the ability to study the shape of particles produced would therefore be a limelight of modern nanotechnology. The bacterial strain Escherichia coli, used for the biosynthesis of silver nanoparticles were investigated. These silver nanoparticles were characterized by means of UV–vis spectroscopy, particle size analyzer. T...

Lactobacillus plantarum MTCC 1407 represents a valuable source of an economically attractive stable long-life tannase with potential for application in various industries. The effect of fermentation parameters such as pH, temperature and agitation speed on the growth of biomass and production of tannase using liquid medium were determined at the en...
Article
Tannase (tannin acyl hydrolase, E.C.3.1.1.20) is an extracellular hydrolase enzyme that catalyzes the hydrolysis of aster and depside bonds in hydrolysable tannins or gallic acid esters, liberating glucose and gallic acid (GA). Tannase cleaves the ester linkages between galloyl groups present in various compounds such as epigallocatechin and epigal...

Tannase also referred to as tannin acyl hydrolase (EC 3.1.1.20), is mainly used for the bioconversion of tannic acid (hydrolysable) to nine parts of gallic acid and one molecule of sugar moiety (Lekha and Lonsane, 1997) (Fig 1). Tannase is widely present in many tannin-rich plant materials, such as myrobalan (Terminalia chebula) fruits, divi divi (...

Question
If you have prepared the metal nanoparticles (maybe in oxide/mixed form), how could we find the efficacy through in vitro and in vivo studies?
Question
Presently, I am trying to explore the hidden knowledge of siddha formulation. On to this I have started working with Arsenic based formulation. As I am a biotechnologist, I do not have enough ideas of the formulation. If any one could suggest a good review paper/ book, I will be very grateful!
