Production of levansucrase from novel honey Bacillus subtilis isolates capable of producing antiviral levans

The outcome of this study is the probable suitability of the produced levan as a safe and cheap natural product adequate for effective antiviral treatments with applying the known roles concerning the use of these compounds. In this respect, and as far as we are aware nothing was reported on levan as antivirus. In addition, this article affords honey micro flora as a new and important sources of levansucrase enzymes, also it could have biotechnological applications in pharmaceutical industries.
