Microbial Production of Levan using Date Syrup and Investigation of Its Properties

  title={Microbial Production of Levan using Date Syrup and Investigation of Its Properties},
  author={Marzieh Moosavi-Nasab and Behnaz Layegh and Ladan Aminlari and Mohammad Bagher Hashemi},
Levan, an exopolysaccharide, was produced by Microbacterium laevaniformans and its yield was characterized as a function of concentrations of date syrup, sucrose and the fermentation time. The optimum condition for levan production from sucrose was at concentration of 20% sucrose for 48 h and for date syrup was 25% for 48 h. The results show that an increase in fermentation time caused a decrease in the levan production at all concentrations of date syrup tested. Under these conditions after 48… CONTINUE READING
