Abstract

With the advent of single cell oil (SCO) and realization of its multiple prospects and possibilities, it has become a perpetual subject of research interest. SCO can be a fungible alternate feedstock for high value lipids and biofuels. High overall process economy associated with SCO production is the major limitation toward complete acceptance of this biotechnological product, which is majorly contributed by bulk requirement of expensive fermentable carbon. In recent years, research has therefore accelerated in evaluating inexpensive lignocellulosic (LC) feedstocks as a worthy replacement for expensive carbon sources. This chapter throws light on the conversion of lignocellulosic biomass (LCB) to SCO, the practical feasibility and existing bottlenecks in the pathway. Aspects discussed in detail are origin of SCO, oleaginous microorganisms and their mechanism of accumulation, advantages and limitations over conventional oils, LCB as feedstocks to bulk and high value lipids, prospects of SCO, factors influencing the conversion of LCB to SCO and the biorefinery concept. Balanced coproduction of bulk lipids (which can be pursued for biofuels) with valuable functional fatty acids (which can increase the economic value of these oils and to some extent balance the overall expense) is required for practical feasibility of SCO. Co-generation of other valuable products and value addition to byproducts can prove to be the backbone for the techno-economics and hence must also be well engrained in the bioprocess.
