“…In order to study morphological changes in the lignocellulose structure of sugarcane straw after pretreatment, the pretreated biomass was analyzed by SEM (Hitachi TM3000, Chiyoda, TYQ, Japan). For this, dilute acid pretreated sugarcane straw and alkaline pretreated sugarcane straw (cellulose pulp) were subjected to SEM for morphological analysis at 1000× magnification [16].…”

“…Moreover, these raw materials are promising carbon sources and economically competitive ones as compared with food-based carbon sources [14,15]. However, current knowledge about lasiodiplodan synthesis from lignocellulosic biomass is rudimentary and very limited research has been performed in this regard [13,16].…”

Lasiodiplodan is a β-glucan polymer with different interesting characteristics, including therapeutic properties. It is an extracellular product, which is produced by the filamentous fungus Lasiodiplodia theobromae, using glucose as a substrate. In the present work, the production of lasiodiplodan was studied by the utilization of sugarcane straw as a low-cost carbon source. Glucose-rich sugarcane straw hydrolysate was obtained by a sequential pretreatment with dilute nitric acid (1% v/v) and sodium hydroxide (1% w/v), followed by enzymatic hydrolysis. The fermentation process was conducted by the cultivation of the strain Lasiodiplodia theobromae CCT3966 in sugarcane straw hydrolysate in a shake flask at 28 °C for 114 h. It was found that hydrolysate obtained after enzymatic hydrolysis contained 47.10 gL−1 of glucose. Fermentation experiments of lasiodiplodan synthesis showed that the peak yield and productivity of 0.054 gg−1 glucose consumed and 0.016 gL−1 h−1, respectively, were obtained at 72 h fermentation time. Fungal growth, glucose consumption, and lasiodiplodan production from sugarcane straw hydrolysate presented a similar pattern to kinetic models. The study on the chemical structure of lasiodiplodan produced showed it had a β-glucan construction. The current study revealed that sugarcane straw is a promising substrate for the production of lasiodiplodan.

Spent brewer’s yeast (SBY) is a byproduct of the brewing industry traditionally used as a feed additive, although it could have much broader applications. In this paper, a comprehensive review of valorization of SBY for the production of high-value products, new materials, and biofuels, as well as environmental application, is presented. An economic perspective is given by mirroring marketing of conventional SBY with innovative high-value products. Cascading utilization of fine chemicals, biofuels, and nutrients such as proteins, carbohydrates, and lipids released by various SBY treatments has been proposed as a means to maximize the sustainable and circular economy.
