The limited effectiveness of current antibiotics motivates the search for new antibacterial compounds. In this study, a novel strain, RG-5, was isolated from desert soil. This strain exhibited potent antibacterial and antibiofilm properties against multidrug-resistant and biofilm-forming pathogenic bacteria. Through phenotypical characterizations, 16S rRNA gene sequence and phylogenetic analysis, the strain was identified as <i>Streptomyces</i> pratensis with 99.8% similarity. The active compound, RG5-1, was extracted, purified by reverse phase silica column HPLC, identified by ESI-MS spectrometry, and confirmed by <sup>1</sup>H and <sup>13</sup>C NMR analysis as 2,5-Piperazinedione, 3,6-bis(2-methylpropyl), belonging to cyclic peptides. This compound showed interesting minimum inhibitory concentrations (MICs) of 04 to 15 µg/mL and minimum biofilm inhibitory concentrations (MBICs 50%) of ½ MIC against the tested bacteria. Its molecular mechanism of action was elucidated through a molecular docking study against five drug-protein targets. The results demonstrated that the compound RG5-1 has a strong affinity and interaction patterns with glucosamine-6-phosphate synthase at − 6.0 kcal/mol compared to reference inhibitor (− 5.4 kcal/mol), medium with penicillin-binding protein 1a (− 6.1 kcal/mol), and LasR regulator protein of quorum sensing (− 5.4 kcal/mol), confirming its antibacterial and antibiofilm activities. The compound exhibited minimal toxicity and favorable physicochemical and pharmacological properties. This is the first report that describes its production from <i>Streptomyces</i>, its activities against biofilm-forming and multidrug-resistant bacteria, and its mechanism of action. These findings indicate that 2,5-piperazinedione, 3,6-bis(2-methylpropyl) has the potential to be a promising lead compound in the treatment of antibiotic-resistant and biofilm-forming pathogens.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8279,"journal":{"name":"Archives of Microbiology","volume":"206 11","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignocellulosic biomass emerges as a promising renewable bio-energy source capable of fulfilling the world’s energy requirements on a large scale. One of the most important steps in lowering reliance on fossil fuel and lessening environmental effect is turning lignocellulosic biomass into biofuel. As carbon–neutral substitutes for traditional fuel, biofuel offer a solution to environmental concerns compared to conventional fuel. Effective utilization of lignocellulosic biomass is imperative for sustainable development. Ongoing research focuses on exploring the potential of various microorganisms and their co-interactions to synthesize diverse biofuels from different starting materials, including lignocellulosic biomass. Co-culture techniques demonstrate resilience to nutrient scarcity and environmental fluctuations. By utilising a variety of carbon sources, microbes can enhance their adaptability to environmental stressors and potentially increase productivity through their symbiotic interactions. Furthermore, compared to single organism involvement, co-interactions allow faster execution of multistep processes. Lignocellulosic biomass serves as a primary substrate for pre-treatment, fermentation, and enzymatic hydrolysis processes.

AMR phenomenon is genetically encoded, and various genetic determinants have been implicated in their emergence and spread. Nevertheless, several non-genetic phenomena are also involved in antibiotic treatment failure which requires a systematic investigation. It has been observed that in an isogenic population of bacteria, not all cells behave or respond the same way to an antibiotic, because of the inherent heterogeneity among them. This heterogeneity is not always heritable but rather phenotypic. Three distinct types of phenotypic heterogeneity, namely tolerance, persistence, and heteroresistance have been observed in bacteria having significant clinical implications influencing the treatment outcome. While tolerance is when a population can survive high doses of antibiotics without changing the minimum inhibitory concentration (MIC) of the drug, persistence occurs in a subpopulation of bacteria that can survive exposure to high antibiotic doses. In contrast, when a subpopulation shows a very high MIC in comparison to the rest of the population, the phenomenon is called heteroresistance. In this article, we have highlighted bacterial persistence with a focus on their emergence and the underlying molecular mechanisms.
