Background Bacterial biofilms are aggregation or collection of different bacterial cells which are covered by self-produced extracellular matrix and are attached to a substratum. Generally, under stress or in unfavorable conditions, free planktonic bacteria transform themselves into bacterial biofilms and become sessile. Main body Various mechanis...

The biological synthesis of nanoparticles is emerging as a potential method for nanopar- 20 ticle synthesis due to its non-toxicity and simplicity. In the present study, a bacterium resistant to 21 heavy metals was isolated from a metal-contaminated site and we aim to report the synthesis of 22 Fe3O4 nanoparticles via co-precipitation using bacteri...

Metallothioneins (MTs) are small metalloproteins that contain Cysteine residues and provide excellent feasibility for binding metals. They have low molecular mass and are known to carry out a plethora of functions including metal homeostasis, scavenging free radicals, and shield against heavy metals. The expression level of these peptides among inv...

Cellulose is a very abundant polymer that is found in nature. Cellulose has been used as a raw material for production of biofuels for many years. However, there are multiple processing steps that are required so that cellulose can be used as a raw material for biofuel production. One of the most important steps is the breakdown of cellulose into i...

Proteus vulgaris is a pathogenic bacteria that has been found to cause various infections in multiple organisms. It has been primarily found to cause urinary tract infections. These bacteria form very resistant biofilms on the surface of catheters and surgical equipment. Hence it is very important to understand these biofilms and their architecture...

Laccases are multi-copper oxidase enzymes produced by living organisms such as bacteria, fungi and plants. Laccases are widely used by the industry because laccases are abundant and highly efficient. Laccases isolated from microbial sources are less stable and less active. To improve their kinetic properties and reusability, laccases have been immo...

In addition to the ubiquitous roles of cellular RNA in genetic regulations, gene expression and phenotypic variations in response to environmental cues and chemotactic signals, the regulatory roles of a new type of RNA called extracellular RNAs (exRNAs) are an up-and-coming area of research interest. exRNA is transported outside the cell through me...

Introduction: The use of enzymes in various industries has been prevalent for centuries. However, their potency as therapeutics remained latent until the late 1950s, when scientists finally realized the gold mine they were sitting on. Enzyme therapy has seen rapid development over the past few decades and has been widely used for the therapy of myr...

Serrapeptase is a proteolytic enzyme with many favourable biological properties like anti-inflammatory, analgesic, anti-bacterial, fibrinolytic properties and hence, is widely used in clinical practice for the treatment of many diseases. The activity of microbial enzymes is usually low and hence enhancing the enzyme activity is an integral and cruc...

Metagenomics is a technology employed to study genetic material directly isolated from environmental samples. Metagenomics thus reveals knowledge on microbial communities of uncultivable organisms in environmental niches, using screening technologies based on sequence and function. Applications include the identification of novel bacteria or gene c...
