Special Issue Information

Dear Colleagues,

Biomass has tremendous potential as a net-zero feedstock and the global annual generation of biomass waste is in the order of 140 Gt. To achieve the net-zero global emission by 2050, governments and companies worldwide are pledging to highly efficient utilization of biomass waste. Functional carbon products derived from biomass waste have promising application potentials in several fields including energy storage, catalysis, purification, metallurgy, and so on. More importantly, the biomass-derived carbon products fixed photosynthetic carbon. Once these carbon products are intended for long-term use, the carbon could serve as negative carbon to contribute to net negative emissions.

The scope of the Processes journal covers research in chemistry, biology, materials, and allied engineering fields. Thus, in this Special Issue, we invite articles focused on research regarding materials and allied engineering firms.

The special issue will focus on publishing the original research works related to the Lignocellulosic Biomass Pretreatment and Conversion Processing Technology to Produce Functional Carbon Products. Experimental research for high-quality carbon product fabrication, process modeling and assessment for system evaluation, and reviewing works for the summary of the state of art research are all welcome.

Topics of interest for this Special Issue include but are not limited to:

  • Biomass-derived carbon for energy storage applications such as battery anodes and supercapacitors;
  • Biomass-derived carbon for metallurgy applications;
  • Biomass-derived carbon for catalysis and purification applications;
  • Efficient biomass pretreatment/conversion technology for carbon production;
  • Overall system analysis and evaluation of a biomass pretreatment/conversion technology with functional carbon as a major product or a coproduct.

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. Full article

High-potential nanomaterials were derived from rice straw using the integrated biobased processes of enzymatic hydrolysis with green organic acid hydrolysis assisted with ultrasonication pretreatment. The optimization condition of nanocellulose preparation by enzymatic hydrolysis via central composite design (CCD) achieved a maximum nanocellulose content of 32.37 ± 0.47% using a cellulase concentration of 107.06 U/mL and 0.13% (w/w) of rice straw cellulose. The ultrasonication-assisted pretreatment prior to enzymatic hydrolysis improved nanocellulose preparation to 52.28 ± 1.55%. Integration with oxalic acid hydrolysis increased the nanocellulose content to 64.99 ± 0.16%. Granular nanocellulose was obtained and consisted of a 105–825 nm nanosize with a zeta potential value of −34.5 mV, and nanocellulose suspension showed high stability without aggregation. In addition, the remaining rice straw cellulose after oxalic acid was microcrystalline nanocellulose. All prepared nanocellulose represented a functional group as original cellulose but had a low crystallinity index (CrI) of 15.68% that could be classified as amorphous nanocellulose. Based on their characteristics, all nanocellose could be further applied in food, cosmetics, and pharmaceuticals. Moreover, the results indicated that the rice straw could be an alternative non-edible cellulose source for preparing potential nanocellulose via a controlled hydrolysis process. Full article
