Special Issue Information

Dear Colleagues,

Fermented dairy products have been a staple food commodity throughout recorded human history. Even before the discovery of microorganisms, humans had tamed fermentation and through its exploitation had been able to produce a wide range of dairy products. Through trial and error, a wealth of technical wisdom was generated that was passed through generations, reaching present times.

Over the last century, the microorganisms that drive dairy fermentation, the factors that affect their growth and persistence, along with the effect of their metabolic end products on human health, have been extensively assessed. In recent years, the development of techniques that are able to produce huge amount of data, allowed the exploration of understudied aspects of microbial subsistence, facilitating our understanding on the biotic and abiotic factors that direct the dairy products’ microcommunity development. In addition, several bioactive compounds generated through microbial metabolism that have a direct or indirect effect on human health, have been described. All these inevitably lead to the current trend of product customization. The capacity for product customization depends upon our ability to understand and effectively control microbial growth and metabolism. The early attempts in this direction provided very promising results, indicating that we are one step closer to the next target, which is personalized nutrition.

The aim of this Special Issue is to collect articles that improve our knowledge of fermented dairy products’ microecosystem development, the metabolism of related microorganisms, product design and evaluation of their safety and functional potential.

The shift from fossil fuels to renewable energy sources is crucial in addressing environmental challenges. Vegetable oils have been focused on as the main potential source for biodiesel and biolubricant production. However, due to their fatty acid (FA) composition they are characterized by low stability to oxidation and variable viscosity. Single-cell oils (SCOs) from oleaginous microorganisms are a possible alternative to vegetable oils: their composition is more suitable, and it can further be improved by controlling the fermentation’s physiological conditions. In the present study, the production of SCOs with targeted technological properties from Lipomyces starkeyi in fermentation under controlled temperatures was assessed. A dairy effluent (scotta) was used as the fermentation substrate to improve the economic sustainability of the process. Batch aerobic fermentations were carried out in a fermenter at two different temperatures (25 °C and 30 °C). The fermentation yields and SCO FA profiles were analyzed. The highest yields of biomass (9.76 g L−1) and microbial oil (1.83 g L−1) were obtained from fermentations carried out at 30 °C. Furthermore, a significantly lower content (46% vs. 55%) of unsaturated FAs and higher content (11% vs. 1.5%) of shorter-chain saturated FAs, with myristic acid almost matching stearic acid, were detected at 30 °C in comparison to 25 °C. Very low peroxide values were also found (0.14 meq O2 kg−1 at 30 °C and 0 meq O2 kg−1 at 25 °C). These results indicate that these SCOs were highly oxidation-resistant, and that a higher fermentation temperature improves their oxidative stability and tribophysical features. The biodiesels’ technological properties, calculated from the FA composition, were within the limits of both U.S. standards and E.U. regulations. Then, SCOs produced from L. starkeyi by fermentation of dairy effluents carried out under controlled temperature can be considered a suitable alternative to vegetable oils to produce biodiesel and biolubricants.
