L-glutaminase of Vibrio sp. from White-Spot Virus disease out-broken shrimp pond
Abstract: Bacteria from White Spot Viral (WSV) disease out-broken shrimp (Penaeus monodon) pond sediments located in the bank of Vellar estuary, South east coast of India were enumerated, enriched, screened by plate assay and confirmed as Vibrio sp. through biochemical tests. Extracellular L-glutaminase was eluted from Vibrio sp. by centrifugation and purified by downstream process. The final yield was 1.7% with 15.4 IU mg-1 of specific activities, which was 17.2 fold …

Disease: A Major Stumbling Block in the Growth of Aquaculture
Abstract: Aquaculture plays a crucial role in ensuring food security, fostering economic development, and providing recreational opportunities worldwide. However, the intensification of aquaculture practices has led to a surge in environmental challenges, including water pollution, soil acidification, eutrophication, chemical contamination, and the spread of diseases. Among these, diseases caused by bacteria, viruses, fungi, and parasites pose significant threats to the sustainability of global aquaculture. Despite the implementation of various diagnostic methods …

Bacterial Infected Diseases on Fish Clarias Batrachus Treated by Nanoparticle
Abstract: An experiment was designed to investigate the antibacterial activity of two nanoparticles against fish bacterial pathogens Bacillus subtilis, Vibrio harveyi species. Different concentration of nanoparticles was assessed by well diffusion method against an antibacterial activity. The nanoparticles was analysed by MIC and MBC technique. The potential nanoparticle CeO2 which showed maximum antibacterial was also subjected for the time killed assay method. Among the two nanoparticles CeO2 shows maximum activity against …

Multiplex PCR Assay for Rapid Detection of Different Strains of Escherichia coli Associated with Fish and Fishery Products
Abstract: A multiplex PCR (MPCR) assay was developed for the detection of Escherichia coli using selected primers designated on the species- and strains-specific genes such as hlyA, LT1 and phoA. The internal regions amplified were having a product size of 165, 275, and 903 bp, respectively. This MPCR assay had a sensitivity of detecting four cells of E. coli within 10 h in artificially contaminated shrimp tissue homogenate. The MPCR assay …

A Comparative Study of Plant Mediated Synthesis of Silver, Copper and Zinc Nanoparticles from Tiliacora acuminata (lam.) Hook. F. and Their Antibacterial Activity Studies
Abstract: Green synthesis of nanoparticles is becoming more and more popular due to its compensation over physical or chemical methods. This research was carried out to the synthesis of nanoparticles employing three different metals (silver nitrate, copper and zinc sulphate) using Tiliacora acuminata (family: Menispermaceae) fruit powder. The synthesized nanoparticles were characterized through the UV-Vis Spectrophotometer, FT-IR and X-Ray Diffraction studies. The antibacterial activity of nanoparticles was studied against disease causing …

Synthesis and Characterization of Silver Nanoparticles by using Aqueous Leaf Extract of Tecomella Undulata (SM.) seem. and their Antibacterial Properties
Abstract: Abstract The efficient protocol for bio-synthesis of silver nanoparticles (AgNPs) using Tecomella undulata leaves was developed. The present study revealed that bio-active compounds and secondary metabolites present in the aqueous extract function as stabilizing agent for AgNPs. UV-Visible spectro-analysis and FTIR confirm the presence of bioactive compounds and TEM, EDX and XRD studies confirm the crystalline nature, structure and surface morphology of silver nanoparticles produced from the plant Tecomella undulata. …

Extracellular Biosynthesis of Silver Nanoparticles using the Fungus Pleurotus ostreatus and their Antibacterial Activity
Abstract: In the present study, an eco-friendly process for the synthesis of nanomaterials using a fungus (Pleurotus ostreatus) has been attempted. The fungus supernatant of seed culture was used for the biosynthesis of silver nanoparticles. The aqueous silver ions were reduced to silver metal nanoparticles when treated with the fungal supernatant. After 72h of treatment, silver nanoparticles were obtained. These silver nanoparticles were characterized by UV–Vis spectroscopy, scanning electron microscopy (SEM), …

Whispers of the Microbial World: Unveiling Bacterial Dialogues through Quorum Sensing
Abstract: Quorum sensing is a special way of bacteria by which they can regulate their own gene expression as per the population density of the bacteria. It is basically a type of cell-to-cell communication pathway used by the microbes. The signal molecule which helps in this mechanism are called auto inducer(AI). As the mechanism depends by changes in the cell density, so when the cell density reaches to the threshold cell …
