“…With the consumption of a large amount of glutinous rice, the hydrolysis of soluble polysaccharides and the water molecule ratio’s metabolism increased gradually, and the solid stage changed to the liquid stage. As a result, the Rhizopus and yeast metabolic process produced a large amount of organic acid. − Consequently, the higher acid concentration increased the [H + ] proportion gradually, which was determined by the fermented liquid’s acid content.…”

A two-stage process was used to prepare rice alcohol, i.e., saccharification of glutinous rice by Rhizopus nigricans Q3, followed by Saccharomyces cerevisiae's fermentation. Rhizopus nigricans Q3 was cultured during the saccharification stage, and Saccharomyces cerevisiae GY-1 was added in the fermentation stage. Total sugar content and reducing sugar content in these two stages were analyzed. The relationship between the production proportion and consumption of the reducing sugar in the saccharification interval was analyzed using reducing sugar indices. It is an important rule that the high-concentration syrup and oligosaccharides prepared by glutinous rice could reach 42°Bx and 250 mg/mL by high-concentration fermentation in the growth stage of R. nigricans Q3.

“…After that, cellulose can be metabolized by mildew for the release and extraction of the remaining biological functional components. Mildew in HL and Qu, such as Rhizopus , have a good performance in cellulose hydrolyzation and organic acid production, which can further increase the biological functional components’ concentration [ 93 , 94 ]. After the extraction of the biological functional components, methanogenic bacteria ( Methanothermobacter ) can be inoculated.…”

Huangjiu lees (HL) is a byproduct in Chinese Huangjiu production with various nutrient and biological functional components. Without efficient treatment, it could cause environmental issues and bioresource wasting. Existing dominant recovery approaches focus on large-scale disposal, but they ignore the application of high-value components. This study discusses the advantages and limitations of existing resourcing approaches, such as feed, food and biogas biological production, considering the efficiency and value of HL resourcing. The extraction of functional components as a suggestion for HL cascade utilization is pointed out. This study is expected to promote the application of HL resourcing.

“…120 Microbial production of LA is a cost-effective process as it uses residues of agriculture waste as a substrate and is fermented using bacteria, such as Carnobacterium , Enterococcus , Lactobacillus , Lactococcus , Pediococcus , and Tetragenococcus , and several fungi, such as Mucor , Monilia , Rhizopus , and Yeast , which are capable of producing LA. 121 There are several reports supporting LA production using microbes that use natural substances; for instance, a mixed consortium of B. coagulans LA1507 and L. rhamnosus uses sweet sorghum juice as a substrate, 122 L. paracasei A-22 uses potato stillage, 123 L. bulgaricus uses dairy waste, 124 R. oryzae uses tobacco waste, 125 L. delbrueckii ssp. Lactis uses Kodo millet bran residue, 126 and Pediococcus acidilactici uses wheat straw.…”

The methods available for the disposal of synthetic polymers are not advanced in an environment-friendly way. Consequently, their waste persists as a non-degradable pollutant that discharges toxic substances, which have now reached the deepest parts of the ocean. As an alternative, biopolymers such as polylactic acid, polyhydroxyalkanoates, and poly(butylene succinate), synthesized from natural sources such as plants, animals, and microbes, are an eco-friendly option, as they are biodegradable and a better option to shift from synthetic polymer dependency. The fabrication of electrospun nanofibers (NFs) using biopolymers is a novel approach, by which new ideas have been proposed in various fields, such as agriculture, biomedical, food packing, textiles, adsorption, drug delivery, three-dimensional printing, etc. Electrospun NFs are receiving increasing attention due to their diverse properties, including flexibility. This review provides a perception of the novel biopolymers that are currently utilized by the electrospun technique and their various applications.
