“…(formerly known as Rhodosporidium), Yarrowia lipolytica, and Lipomyces sp. Interestingly, the oleaginous yeast Rhodosporidium toruloides was considered an industrial potential single-cell microbe that showed a high potential to accumulate higher amounts of lipids that were used as a feedstock for biodiesel production [53][54][55]. In the current investigation, we aimed to optimize lipid accumulation by the yeast isolate Rhodotorula toruloides Y1124 using the Plackett-Burman design and central composite design in order to maximize the lipid accumulation capability by the oleaginous yeast for biodiesel production.…”

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.

“…Another research has evaluated the bioconversion of fermentable sugars derived from WH into microbial lipids and single cell proteins by an oleaginous yeast. This study indicated the feasibility of sustainable valorization of WH-derived liquid hydrolysate towards a biorefinery framework Alankar et al (2021). By the way, Arutselvy et al (2020), have conducted a sequential valorization strategy for dairy wastewater (DW) and WH to produce fuel and fertilizer.…”

The proliferation of the invasive Water hyacinth (WH) plant leads to ecological, economic, public health, and agricultural problems. Several efforts have been deployed to control its spread, but no concreate results have been obtained. Only few studies dealing with systematic approaches for the WH control have been conducted. To establish a road map for the best control methods to be adopted, this review highlights the control programs that have been tested worldwide and describes, through a deep literature analysis and comparison, the most effective and sustainable control programs for managing the proliferation of this aquatic weed. Through a critical analysis, this review evaluates the advantages and drawbacks of the main proposed control methods including biological, chemical and physical methods. The obtained results suggested that short and medium term physical control promptly manages the plant’s proliferation and thus could complement the effect of the biological control. Moreover, to be economically viable, the harvested WH through physical means must be valorized to generate high value-added products. Furthermore, run-off nutrients control could reduce the end-of-catchment loads and would help the resilience of freshwater bodies and promote plant removal. Descriptive results analysis confirmed that an integrated control approach combining “biological and physical’’ is the most sustainable and cost-effective approach. The adaptation of these methods based on the socio-economic context of each country, could promote ecosystem restoration, self-generation, and conservation for a sustainable development.

“…In another study, water hyacinth was initially subjected to microwave‐acid pre‐treatment for obtaining liquid hydrolysate containing sugars derived from holocellulosic components of the biomass. This hydrolysate was further subjected to fermentation for the production of microbial lipids and single cell protein using the oleaginous yeast Rhodosporidium toruloides NCIM 3547 71 . After pre‐treatment, the inhibitors such as furans were detoxified using the over‐liming process and both the detoxified and non‐detoxified hydrolysates were used for the production of microbial lipids and single‐cell proteins.…”

“…The results indicated that the reducing sugar concentration was found to be higher in the non‐detoxified hydrolysate (65.41 g L −1 ) than the detoxified one (59.18 g L −1 ). In the non‐detoxified liquid, the maximum lipid yield of about 0.813 ± 0.041 (g g −1 ) and 53.60 ± 2.68 (g g −1 ) of single cell protein content with 0.038 g L −1 per day of protein productivity was achieved 71 . The increasing demand for bioenergy and other bio‐based products presents an opportunity for extending further research on channeling the use of this invasive aquatic plant in biorefinery concepts.…”

The development of biorefineries is a crucial step in the circular economy framework. In biorefineries, research is intensified towards utilizing feedstocks, which do not need arable land or compete with food sources. In this scenario, emerged, submerged and free-floating aquatic plants are garnering significant attention as potential feedstocks owing to their generation in huge quantities, especially in eutrophic water bodies, similar composition to lignocellulosic biomass with lower lignin content and requirement for only mild pre-treatments. Therefore, exploring the feasibility of using these aquatic plants for the production of various biocommodities in a biorefinery approach can be of prime importance. In light of this, the current review illustrates the use of some of the major aquatic plants for the production of different biocommodities. The main focus of the study is to shed light on the various biorefinery schemes that could be implemented using these aquatic plants. It also outlines the challenges and prospects of aquatic plant-based biorefineries. The findings suggest that various biorefinery schemes can be implemented using these aquatic plants and a combination of chemical and biological processes could aid in lowering the cost and achieving better yields. Furthermore, it is also observed that research on large-scale management and valorization of these aquatic plants also needs to be intensified.
