“…It was demonstrated that different Bacillus strains provide EPSs with anti-cancer properties such as Bacillus mycoides [ 26 ], Bacillus spp . [ 27 ], and Lactobacillus delbrueckii Our isolated strain; B. sonorensis SAmt2 was capable of producing EPS-1 which showed an anti-cancer activity as demonstrated in our previous work [ 18 ] and in the current study.…”

“…The tolerance and stability exhibited by B950 and to a lesser extent by B961 are rarely reported among the B. licheniformis representatives, although these species otherwise had good output as enzyme producers (Díaz-Cornejo et al, 2023). However, a previous study reported by Asitok et al, (2022) observed that the ability of a bacterial strain to withstand multiple extreme conditions, such as high pH, temperature, and salinity is crucial; as the enzyme yield can be reasonably optimized.…”

Proteases; especially alkaline proteases, constitute the most used group of enzymes in industry. The wide scope of their application requires varying properties; most commonly stability throughout the conditional changes that would occur during the various industrial processes. This study aimed to identify the potentially interesting bacterial strains obtained from Moroccan extreme environment, and evaluate their proteolytic activity under the various growing conditions. In this study, the impact of temperature and salinity on the alkaline protease activity (pH 11) of 33 Bacillus strains deposited in the Moroccan Coordinated Culture Collection, which originated from the various extreme environments from Morocco, was studied. Bacterial identification to the species level was performed using 16S rRNA gene sequencing and MultiLocus Sequence Typing (MLST), a technique that is much more precise and can identify the bacteria to the strain level. Strain B950 showed a relatively stable protease activity at the tested extreme conditions (i.e., 130.8 U/ ml at 60 °C and 10 % NaCl). On the other hand, strain B961 displayed a better overall activity at either high temperature (140.8 U/ ml) or salinity (137 U/ ml); however, it was not as stable as when grown under both extreme conditions. Regarding identity of the bacterial strains, they were all representatives of Bacillus licheniformis; although B950 and B961 strains belonged to Sequence Types 3 and 5, respectively.

“…They also include Gram-positive bacteria of such classes as Bacilli including Bacillus , Paenibacillus , Lactobacillus , Leuconostoc , and Streptococcus genera; class Clostridia including Sarcina sp. ; and class Actinomycetia including Bifidobacterium , Rhodococcus genera, and others [ 2 , 16 , 17 ]. Some of the most commonly used EPSs are xanthan from the genus Xanthomonas , dextran from the Leuconostoc , Streptococcus , and Lactobacillus genera, alginate from the Azotobacter and Pseudomonas genera, curdlan from Alcaligenes faecalis , Rhizobium radiobacter , and Agrobacterium sp., gellan from the Sphingomonas and Pseudomonas genera, hyaluronan from Streptococcus sp., levan from Bacillus sp., Paenibacillus sp., Halomonas sp., and Zymomonas sp., bacterial cellulose from Komagataeibacter sp., and others.…”

Bacterial exopolysaccharides (EPS) are essential natural biopolymers used in different areas including biomedicine, food, cosmetic, petroleum, and pharmaceuticals and also in environmental remediation. The interest in them is primarily due to their unique structure and properties such as biocompatibility, biodegradability, higher purity, hydrophilic nature, anti-inflammatory, antioxidant, anti-cancer, antibacterial, and immune-modulating and prebiotic activities. The present review summarizes the current research progress on bacterial EPSs including their properties, biological functions, and promising applications in the various fields of science, industry, medicine, and technology, as well as characteristics and the isolation sources of EPSs-producing bacterial strains. This review provides an overview of the latest advances in the study of such important industrial exopolysaccharides as xanthan, bacterial cellulose, and levan. Finally, current study limitations and future directions are discussed.
