“…The literature on fundal biopolymers recognizes the two primary properties of fungi, on which different industries have capitalized on to produce biopolymers using the microorganisms; they are fast growing and can convert nutrients from low-cost and lowvalue waste into biopolymers [13]. Consequently, fungal waste from wineries, which includes saccharomyces and non-saccharomyces yeasts, waste from enzyme production, which includes Aspergillus and Trichoderma, penicillium waste from the manufacture of antibiotics, and waste from the mushroom industry are up-scaled for use in the production of fungal exopolysaccharides such as Aureobasidium, Sclerotium, and Botryosphaeria [14]. Lactobacillus bulgaricus, lactobacillus delbrueckii, and lactobacillus leichmannii are used in the fermentation process in the production of the monomers that are polymerized in the second step to form the monomers that undergo ROP to produce polyester [11].…”

Research efforts have shifted to creating biodegradable polymers to offset the harmful environmental impacts associated with the accumulation of non-degradable synthetic polymers in the environment. This review presents a comprehensive examination of the role of green microbes in fostering sustainable bioproduction of these environment-friendly polymers. Green microbes, primarily algae and cyanobacteria, have emerged as promising bio-factories due to their ability to capture carbon dioxide and utilize solar energy efficiently. It further discusses the metabolic pathways harnessed for the synthesis of biopolymers such as polyhydroxyalkanoates (PHAs) and the potential for genetic engineering to augment their production yields. Additionally, the techno-economic feasibility of using green microbes, challenges associated with the up-scaling of biopolymer production, and potential solutions are elaborated upon. With the twin goals of environmental protection and economic viability, green microbes pave the way for a sustainable polymer industry.

“…The extraction of β-glucan from bacterial cell walls is one technological innovation that lacks sufficient scientific data [ 49 ]. Thus, Gemilang Lara Utama et al [ 50 ] state that the β-(1→3)-glucan component in the cell walls of yeasts and bacteria such as Xanthomonas campertris and Bacillus sp.…”

The article systematizes information about the sources of β-glucan, its technological functions and practical aspects of its use in dairy and milk-based products. According to the analysis of scientific information, the main characteristics of β-glucan classifications were considered: the source of origin, chemical structure, and methods of obtention. It has been established that the most popular in the food technology of dairy products are β-glucans from oat and barley cereal, which exhibit pronounced technological functions in the composition of dairy products (gel formation, high moisture-binding capacity, increased yield of finished products, formation of texture, and original sensory indicators). The expediency of using β-glucan from yeast and mushrooms as a source of biologically active substances that ensure the functional orientation of the finished product has been revealed. For the first time, information on the use of β-glucan of various origins in the most common groups of dairy and milk-based products has been systematized. The analytical review has scientific and practical significance for scientists and specialists in the field of food production, in particular dairy products of increased nutritional value.

β-1,6-Glucan plays a crucial role in fungal cell walls by linking the outer layer of mannoproteins and the inner layer of β-1,3-glucan, contributing significantly to the maintenance of cell wall rigidity. Therefore, the hydrolysis of β-1,6-glucan by β-1,6-glucanase directly leads to the disintegration of the fungal cell wall. Here, a novel β-1,6-glucanase FlGlu30 was identified from the endophytic Flavobacterium sp. NAU1659 and heterologously expressed in Escherichia coli BL21 (DE3). The optimal reaction conditions of purified FlGlu30 were 50℃ and pH 6.0, resulting in a specific activity of 173.1 U/mg using pustulan as the substrate. The hydrolyzed products of FlGlu30 to pustulan were mainly gentianose within 1 h of reaction. With the extension of reaction time, gentianose was gradually hydrolyzed to glucose, indicating that FlGlu30 is an endo-β-1,6-glucanase. The germination of Magnaporthe oryzae Guy11 spores could not be inhibited by FlGlu30, but the appressorium formation of spores was completely inhibited under the concentration of 250.0 U/mL FlGlu30. The disruptions of cell wall and accumulation of intracellular reactive oxide species (ROS) were observed in FlGlu30-treated M. oryzae Guy11 cells, suggesting the significant importance of β-1,6-glucan as a potential antifungal target and the potential application of FlGlu30. Key points • β-1,6-Glucan is a key component maintaining the rigid structure of fungal cell wall. • β-1,6-Glucanase is an antifungal protein with significant potential applications. • FlGlu30 is the first reported β-1, 6-glucanase derived from Flavobacterium.
