“…Highest MUFA and PUFA contents were achieved in R. glutinis cultivated in Th and PCon hydrolysates, respectively. Irrespective of cultivation medium, fatty acid profiles and elongation and desaturation patterns were typical for R. glutinis and de novo lipid synthesis [43]. In line with other reports, oleic acid (C18:1) and linoleic acid (C18:2) were the main MUFA and PUFA of R. glutinis cultivated in CRFW hydrolysates [16,23,44].…”

Bio-Refining of Carbohydrate-Rich Food Waste for Biofuels

Abstract:The global dependence on finite fossil fuel-derived energy is of serious concern given the predicted population increase. Over the past decades, bio-refining of woody biomass has received much attention, but data on food waste refining are sorely lacking, despite annual and global deposition of 1.3 billion tons in landfills. In addition to negative environmental impacts, this represents a squandering of valuable energy, water and nutrient resources. The potential of carbohydrate-rich food waste (CRFW) for biofuel (by Rhodotorulla glutinis fermentation) and biogas production (by calculating theoretical methane yield) was therefore investigated using a novel integrated bio-refinery approach. In this approach, hydrolyzed CRFW from three different conditions was used for Rhodotorulla glutinis cultivation to produce biolipids, whilst residual solids after hydrolysis were characterized for methane recovery potential via anaerobic digestion. Initially, CRFW was hydrolysed using thermal-(Th), chemical-(Ch) and Th-Ch combined hydrolysis (TCh), with the CRFW-leachate serving as a control (Pcon). Excessive foaming led to the loss of TCh cultures, while day-7 biomass yields were similar (3.4-3.6 g dry weight (DW) L −1 ) for the remaining treatments. Total fatty acid methyl ester (FAME) content of R. glutinis cultivated on CRFW hydrolysates were relatively low (~6.5%) but quality parameters (i.e., cetane number, density, viscosity and higher heating values) of OPEN ACCESSEnergies 2015, 8 6351 biomass extracted biodiesel complied with ASTM standards. Despite low theoretical RS-derived methane potential, further research under optimised and scaled conditions will reveal the potential of this approach for the bio-refining of CRFW for energy recovery and value-added co-product production.

“…The pattern of a R. glutinis strain in different wastewaters from fruit juice, potato and lettuce processing was described by Schneider et al [37]. None of the wastewaters allowed for significant lipid production by R. glutinis due to the most important limiting factors for lipid production in the screened wastewaters seem to be the low content of available carbon sources in fruit juice and lettuce processing waters and the high content of nitrogen in potato processing waters, respectively.…”

Abstract:Biodiesel has become more attractive in recent years because of its environmental benefits. One way to reduce the high cost of biodiesel is by lowering the cost of raw materials specially oils. Recently, much attention has been paid to the development of microbial oils through cultures of oleaginous microorganisms in inexpensive substrates as the wastewaters of some food industries and the crude glycerol from biodiesel production itself. Thus, cultivation of oleaginous yeasts in glycerolbased media is attracting great interest and natural biodiversity is increasingly explored to identify novel oleaginous species recycling this carbon source for growth and lipid production. Identification of oleaginous yeasts and the evaluation in glycerol and vinasse mixtures was employed to produce biomass enriched in microbial lipids and to remove nutrients from vinasse simultaneously. The fatty acid composition of the lipids was similar to that from plant oils and other microbial lipids therefore they can be used as raw material for feed additives and biodiesel production.
