Molecular Study of Indigenous Bacterial Community Composition on Exposure to Soil Arsenic Concentration Gradient

Polish Journal of Microbiology (2017)

Semanti Basu Tanima Paul Priya Yadav Abhijit Debnath Keka Sarkar

Community structure of bacteria present in arsenic contaminated agricultural soil was studied with qPCR (quantitative PCR) and DGGE (Denaturing Gradient Gel Electrophoresis) as an indicator of extreme stresses. Copy number of six common bacterial taxa (Acidobacteria, Actinobacteria, α-, β- and γ-Proteobacteria, Firmicutes) was calculated using group specific primers of 16S rDNA. It revealed that soil contaminated with low concentration of arsenic was dominated by both Actinobacteria and Proteobacteria but a shift towards Proteobacteria was observed with increasing arsenic concentration, and number of Actinobacteria eventually decreases. PCA (Principle Component Analysis) plot of bacterial community composition indicated a distinct resemblance among high arsenic content samples, while low arsenic content samples remained separated from others. Cluster analysis of soil parameters identifies three clusters, each of them was related to the arsenic content. Further, cluster analysis of 16S rDNA based DGGE fingerprint markedly distributed the soil bacterial populations into low (< 10 ppm) and high (> 10 ppm) arsenic content subgroups. Following analysis of diversity indices shows significant variation in bacterial community structure. MDS (Multi Dimensional Scaling) plot revealed distinction in the distribution of each sample denoting variation in bacterial diversity. Phylogenetic sequence analysis of fragments excised from DGGE gel revealed the presence of γ-Proteobacteria group across the study sites. Collectively, our experiments indicated that gradient of arsenic contamination affected the shape of the soil bacterial population by significant structural shift.

Potential application of superparamagnetic nanoparticles for extraction of bacterial genomic DNA from contaminated food and environmental samples

Journal of the Science of Food and Agriculture (2012)

Semanti Basu Saptarshi Chatterjee Arghya Bandyopadhyay Keka Sarkar

Abstract BACKGROUND: Isolation of high‐molecular‐weight DNA is essential for many molecular biology applications. Owing to the presence of polymerase chain reaction (PCR) inhibitors, there is a scarcity of suitable protocols for PCR‐ready DNA extraction from food and natural environments. The conventional chemical methods of DNA extraction are time consuming and laborious and the yield is very low. Thus the aim of this research was to develop a simple, rapid, cost‐effective method of genomic DNA extraction from food (milk and fruit juice) and environmental (pond water) samples and to detect bacterial contaminants present in those samples. RESULTS: This approach is efficient for both Gram‐positive and Gram‐negative bacteria from all the studied samples. Herein super paramagnetic bare iron oxide nanoparticles were implemented for bacterial genomic DNA isolation. The method was also compared to the conventional phenol–chloroform method in the context of quality, quantity and timing process. This method took only half an hour or less to obtain high‐molecular‐weight purified DNA from minimum bacterial contamination. Additionally, the method was directly compatible to PCR amplification. CONCLUSION: The problem of availability of suitable generalized methods for DNA isolation from various samples including food and environmental has been solved by a nanobiotechnological approach that may prove to be extremely useful in biotechnological applications. © 2012 Society of Chemical Industry
