Abstract
A new isolate was investigated from soil sample collected from Shahrasti upazilla of Chandpur district of Bangladesh. Based on the physico-chemical studies the strain was identified as gram positive Bacilli. Moleculer characterization of the strain was identified as Bacillus aryabhattai which is the first report in Bangladesh. The strain can survive in extreme conditions of salt, temperature and pH. This strain was further characterized and screened for the ability to produce useful enzymes. The optimum temperature for growth and production of these enzymes was within the temperature range 35oC to 40oC. The pH was found to be 7 for its growth and production of different enzymes when investigated over 48 h of incubation. The isolate produced various extracellular enzymes such as α-amylases, cellulases, β-glucosidases, lipases and proteases. The findings of this study provide useful information of the new strain that has potential biotechnological applications.

Highlights
Cosmic ancestry is a new theory trying to explain the evolution and the origin of life on earth
This development could be the hints of huge paradigm shift or evidence of panspermia – where – bacteria can survive in harsh environment – away from earth like outer space
From novel bacterial isolates genomic DNA was extracted and quantified by Nanodrop Spectrophotometer and PCR was done by Takara PCR thermal cycler
Summary
Cosmic ancestry is a new theory trying to explain the evolution and the origin of life on earth It studies the life on earth was seeded from space, and that life's evolution to superior forms depends on genetic foundations that come from space. It is believed that space contains the ingredients of life, sometimes in chemical form, sometimes in the form of an organism (Arrhenius, 2009; Hoyle & Wickramasinghe, 2000; Wainwright, 2010; Wickramasinghe et al, 2009) This development could be the hints of huge paradigm shift or evidence of panspermia – where – bacteria can survive in harsh environment – away from earth like outer space.
