“…Oleaginous yeasts can utilize various cheap carbon resources, including agro-industrial wastes such as wheat bran, sugarcane molasses, corn husk, wheat straw, and paper mill waste, making SCO production commercially viable and sustainable [ 345 ]. Thus, a series of tailings can be used, reducing the environmental impact of several monocultures and even untreated effluents [ 346 , 347 , 348 , 349 ].…”

Among the most relevant themes of modernity, using renewable resources to produce biofuels attracts several countries’ attention, constituting a vital part of the global geopolitical chessboard since humanity’s energy needs will grow faster and faster. Fortunately, advances in personal computing associated with free and open-source software production facilitate this work of prospecting and understanding complex scenarios. Thus, for the development of this work, the keywords “biofuel” and “nanocatalyst” were delivered to the Scopus database, which returned 1071 scientific articles. The titles and abstracts of these papers were saved in Research Information Systems (RIS) format and submitted to automatic analysis via the Visualization of Similarities Method implemented in VOSviewer 1.6.18 software. Then, the data extracted from the VOSviewer were processed by software written in Python, which allowed the use of the network data generated by the Visualization of Similarities Method. Thus, it was possible to establish the relationships for the pair between the nodes of all clusters classified by Link Strength Between Items or Terms (LSBI) or by year. Indeed, other associations should arouse particular interest in the readers. However, here, the option was for a numerical criterion. However, all data are freely available, and stakeholders can infer other specific connections directly. Therefore, this innovative approach allowed inferring that the most recent pairs of terms associate the need to produce biofuels from microorganisms’ oils besides cerium oxide nanoparticles to improve the performance of fuel mixtures by reducing the emission of hydrocarbons (HC) and oxides of nitrogen (NOx).

“…R. toruloides is related to the phylum Basidiomycota; class Microbotryomycetes; order Sporidiobolales; and family Sporidiobolaceae [43]. R. toruloides showed a high potentiality to accumulate intracellular lipids (single cell oil) to more than 70% of its cell dry weight [44] as well as produce value-added green chemicals, e.g., fatty alcohols, fatty acid esters, carotenoids, sesquiterpenes, and (bio-cement) building block chemicals [45]. Due to the huge demand in the food industry, using lipids produced from edible feedstock for large-scale biodiesel production is not a sustainable practice [46].…”

The current study aimed to investigate the potentiality of yeast isolate Rhodotorula toruloides Y1124 to be used as a feedstock for biodiesel production, and the reutilization of the de-oiled yeast biomass wastes as a biosorbent for the biosorption of Congo red from aquatic solutions was investigated. From screening results, eight yeast isolates were referred to as oleaginous microorganisms, of which yeast isolate Rhodotorula toruloides Y1124 was the highest lipid-accumulating isolate and was used as a feedstock for biodiesel production. The highest lipid accumulation (64.8%) was significantly dependent on the glucose concentration, pH, and incubation temperature according to Plackett–Burman and central composite design results. Under optimized conditions, the estimated amount of biodiesel synthesis from Rhodotorula toruloides biomass represented 82.12% of total analytes. The most prevalent fatty acid methyl esters were hexadecanoic and 11-octadecenoic, comprising 30.04 and 39.36% of total methyl esters which were compatible with plant oils. The optimum biosorption conditions for Congo red removal were pH 6, a 15 min contact time, and an initial dye concentration of 40 mg L−1. The biosorption isothermal and kinetics fitted well with the Langmuir model and the maximal biosorption capacity (qmax) was 81.697 mg g−1. Therefore, the current study may offer a sustainable feedstock with potential viability for both the synthesis of biodiesel and the removal of organic dyes.

“…Nevertheless, according to the Food and Agriculture Organization of the United Nations (FAO), due to the environmental, food competition, and land use change (LUC) concerns inherent to the intensive planting of oil crops such as oil palm, soybean, sunflower, or rape [3], the fears arising from climate change or the war in Ukraine [4] (FAO, 2022), and the more than 10 times higher price of VOs compared with crude oil [3], the interest in analogous low-cost oils such as waste cooking oils [5] or microbial oils produced from residual substrates [6] has strongly grown, supported by market competitiveness and their minimal environmental impacts compared to vegetable oils.…”

Microbial oils can be used as an alternative sustainable and renewable feedstock to fossil reserves for producing lubricants and polyurethane materials. Two oleaginous yeasts were grown on non-detoxified corn stover hydrolysate supplemented with corn steep liquor and mineral medium in shake flasks. Trichosporon oleaginosus DSM 11815 displayed the highest lipid production. This strain was further cultivated in a bench bioreactor, using the same culture medium, under a batch regime. Flow cytometry was used to monitor the T. oleaginosus culture using the dual staining technique (SYBR Green and PI) for cell membrane integrity detection. Values of 42.28% (w/w) and 0.06 g/Lh lipid content and lipid productivity, respectively, were recorded for T. oleaginosus cultivated in the bench bioreactor operated under a batch regime. During the cultivation, most of the yeast cells maintained their integrity. T. oleaginosus has the potential to be used as an oil microbial source for a wide range of industrial applications. In addition, it is robust in adverse conditions such as lignocellulosic hydrolysate exposure and oxygen-limiting conditions. Flow cytometry is a powerful and useful tool for monitoring yeast cultivations on lignocellulosic hydrolysates for cell count, size, granularity, and membrane integrity detection.
