Single Cell Protein Production from Liquefied Petroleum Gas

Processes for producing SCP (Single Cell Protein) from n-paraffin and methanol have already been established. Although gaseous hydrocarbon fermentation has certain problems related to bioengineering1), there are advantages of using gaseous hydrocarbons as raw materials, such as (i) pure raw materials can be made available in abandance (ii) unused substrate can be removed easily from fermentation broth or biomass A considerable number of papers on SCP production using methane as the substrate have been reported2), but only a limited number of papers such as those of Sugimoto et al.3), Akiba et al.4) and McLee et al.5) are available on SCP production from LPG (Liquefied Petroleum Gas).
