In the present study, we have studied the bioremediating capability of bacterial strain against six heavy metals. The strain was isolated from river Yamuna, New Delhi which is a very rich repository of bioremediating flora and fauna. The strain was found to be Gram positive as indicated by Gram staining. The strain was characterized using 16s rRNA gene sequencing and the BlastN result showed its close resemblance with the Cellulosimicrobium sp. As each treatment has its own toxicity eliciting expression of different factors, we observed varied growth characteristics of the bacterial isolate and its protein content in response to different heavy metals. The assessment of its bioremediation capability showed that the strain Cellulosimicrobium sp. has potential to consume or sequester the six heavy metals in this study in the following order iron > lead > zinc > cooper > nickel > cadmium. Thus, the strain Cellulosimicrobium sp. isolated in the present study can be a good model system to understand the molecular mechanism behind its bioremediating capabilities under multiple stress conditions.

Background Owing to its exceptional electronic, mechanical, thermal, as well as optoelectronic characteristics, graphene—a planar sheet with one-atom thickness and made of carbon atoms closely packed in quite a honeycomb crystal lattice—has already earned special consideration. The investigated characteristics or even applications of such a two-dimensional configuration of the structure of carbon have already created novel innovative opportunities in place of all of the future devices as well as nanosystems. Area covered These graphene systems have also been recognized as a potential drug-delivery carrier intended for target specific or even controlled drug delivery, which could be designed by utilizing various internal or external stimuli. Expert opinion This review predominantly focuses on graphene’s synthesis and derivative, design of stimuli-responsive nanosystems, and applications in various fields. It is highlighted that with remarkable progress in graphene-related research, graphene’s overall execution has a long road ahead to go.
