Biofilm technique

Biofilm is an aggregate of microorganisms forming multicellular communities where cells are stuck cooperatively by a produced by oneself Matrix Extracellularis. Biofilm formation by microorganisms is a ubiquitous, omnipresent & active mechanism. This vigorous ability of microbes to form biofilms proves to be a key technique for resisting and surviving in adverse climatic conditions as well as antibacterial compounds. Numerous features of biofilms contributed by component of extracellular matrix and microbial community allows in tolerating adverse conditions.

Aquatic pollution occurs due to the discharge of harmful substances, chemicals or microorganisms into water bodies i.e. a stream, river, lake, ocean, aquifer, or other body of water resulting in contamination & degradation of water quality and rendering it unsuitable for human use or the environment. Many advanced water treatment techniques are followed before discharging this polluted water into the surrounding environment. However some limitations is there. In this context, Biofilms have become the important part of biological treatment of municipal waste water.

Primary and secondary microbial adhesion onto solid surfaces has been the onset of development of a mature biofilm in aqueous environments that is predominantly the mode of bacterial contamination and spread of diseases. Adhesion and co-adhesion assays are therefore useful in understanding the adhesive interactions between microorganism and its surfaces. Various factors influence cell adhesion and biofilm formation, depending on aqueous medium and the type of microorganism in place.

Sounds strange that bacteria can talk to each other, though not verbally like humans but with the help of chemical signals which bacteria produce by forming biofilm, producing virulence factors or developing antibiotic resistance. The process starts only when the bacterial cell reach a threshold density enough to produce signals which can be detected by the receptors.

In recent decades the global emergence the development of multidrug-resistant and pan drug resistance in Pseudomonas aeruginosa has been observed. This opportunistic pathogen is responsible for causing various infections especially in the intensive care units, resulting for almost 10% of nosocomial infections. The resistance to Metallo betalactamase in P. aeruginosa strains has been related with bacterial biofilm formation. So, the aim of this study was to determine the rates of biofilm production and metallo betalactamase production (MBL) among the strains of Pseudomonas aeruginosa.

A plant’s microbiota has various implications for the plant’s health and performance; however, the roles of many microbial lineages, particularly Archaea, have not been explored in detail. In the present study, analysis of archaea-specific 16S rRNA gene fragments and shotgun-sequenced metagenomes was combined with visualization techniques to obtain the first insights into the archaeome of a common salad plant, arugula (Eruca sativa Mill.).

Electrochemistry has been used extensively in the past three decades to determine the chemical composition of environmental samples from the water column, sediments, soils, biofilms, and microbial mats.

Thus, despite the value of these clinical methods, such techniques often result in inconsistent diagnoses, as well as an inability to reliably predict a patient´s response to treatment (Offenbacher et al. 2007). A reason for the limited success in predicting the future course of disease in some individuals is that the clinical phenotype does not reflect the underlying biologic processes that occur at the biofilm-gingival interface (Offenbacher et al. 2007).
