AB  - This study was to select strains which have a strong ability 
  to degrade starch and strain which has a strong ability to synthesize protein 
  from nine strains of three species for mixed strains fermentation of potato 
  starch residue to enrich the protein content for further use as an animal feed 
  and to investigate the optimal combination of selected strains and technical 
  parameters of fermentation process. In the experiment of single strain fermentation, 
  three strains, <i>Candida tropicalis</i> AS 13, <i>Saccharomycopsis fibuligera</i> 
  JS2 and <i>Geotrichum candidum</i> AS 2.2342 were selected for mixed strains 
  fermentation by comparison the degradation rate of starch and the synthesis 
  rate of protein. In the experiment of mixed strains fermentation, the True Protein 
  (TP) content were obtained in the substrate fermented by the three strain combination 
  was higher than two-strain combinations. Then the effects of technical parameters 
  such as inoculation ratio, inoculation method and total inoculum size of solid 
  state fermentation on the TP content were analyzed, respectively. The experiment 
  results showed that the use of potato starch residue fermented with the three-strains 
  combination of <i>C. tropicalis</i> AS 13, <i> S. fibuligera</i> JS2 and <i> 
  G. candidum</i> AS 2.2342 at the ratio of 1:7:2 with total 10 mL inoculum size 
  at the same time can improve TP content by up to 16.1% which would subsequently 
  provide a good feedstuff for ruminants.
