| description | Introduction: In the recent years, application of microorganisms as
green biocatalysts for removing caffeine pollution from industrial wastes and
food caffeinated have been extensively considered. This investigation reports
on optimization of bio-decaffeination process under growing cells of Saccharomyces cerevisiae by using the Taguchi statistical
approach. Materials and methods: Five variables, i.e. caffeine, Zn+2, glucose, peptone
concentrations and time incubation, which have significant effects on
bio-decaffeination process, were selected and L16 (44× 13)
orthogonal array was determined for experimental trials. Caffeine degradation
was estimated by HPLC (High Performance Liquid Chromatography) analysis. Results: Use of Taguchi approach for optimization of design
parameters resulted in about 82.8 % reduction
of caffeine in 48 h incubation when 3g/l peptone, 5mM Zn+2 ion and 5
g/l of caffeine are present in the designed media. Under the optimized
conditions, the yield of degradation of caffeine (5 g/l) by the growing cells of
yeast strain TFS9 has been
increased from 25.5 to 82.8 % which is 3.2 fold higher than the normal yield. The improvement
of caffeine removal after best conditions were made shows the efficiency of Taguchi
experimental design in such studies. Discussion and conclusion: The current investigation is the first report for
successful application of the Taguchi experimental approach to the
bio-decaffeination process. According to
the analysis of experimental results, the present study proposes the potentiality
of the Taguchi approach to enhance the bio-decaffeination performance with the
native strain of Saccharomyces
cerevisiae. |
