This study explored the biotechnological potential of <i>Streptomyces griseorubens</i> NBR14 and <i>Nocardiopsis synnemataformans</i> NBR9 by evaluating their polygalacturonase production from wheat and bean straw, and assessing the enzyme’s efficacy in fruit juice clarification, as well as their ability to decolorize crystal violet. To optimize enzyme production, experiments with four variables were conducted using Box-Behnken design (BBD), followed by analysis of variance (ANOVA). The enzyme was then partially purified using acetone, followed by analyzing its properties and potential applications in fruit juice clarification. The optimal conditions for polygalacturonase (PG) activity by NBR14 and NBR9 were 40 °C, pH 9 and 7, incubation for 7 days, and substrate concentrations 2 and 3 g/100 mL, resulting in enzyme yields of 3.54- and 2.20-folds respectively. Partially purified polygalacturonase resulted in 7.07 and 2.99-fold purification, with recoveries of 33.5% and 16.61%, and specific activities of 177.9 and 72.13 U/mg, respectively. Both NBR14 and NBR9 partially purified polygalacturonase exhibited high relative activity at 40 °C and pH value 7. It remained 90% and 88% active at pH 9.0 and 64% and 81% at 60 °C, respectively. The maximum clarity recorded for apple juice was 82.75% and 85.75%, while orange juice clarity was noted at 61.77% and 83.31% for NBR14 and NBR9, respectively. These results highlight the potential of thermo-alkali stable polygalacturonase from extremophilic actinomycetes as a long-term and cost-effective biocatalyst for agro-waste valorization and industrial fruit juice processing.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"37 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial biodegradation is a promising remediation strategy, yet microbial efficiency varies based on species and experimental conditions. However, comparative studies evaluating the performance of single-species and dual-species degradation of polypropylene microplastics (PPMPs) remain limited. Therefore, the present study investigated the PPMP- degradation potential of <i>Pseudomonas aeruginosa</i>, <i>Bacillus subtilis</i>, and <i>Lactobacillus plantarum</i> in single- and dual-species systems over a 30-day incubation period under controlled conditions on PPMPs. Growth kinetics, weight loss, FTIR spectroscopy, SEM imaging, and GC–MS analysis were employed to assess microbial degradation of PPMPS. The results demonstrated significant MP degradation in the presence of all bacterial species, with the dual-species model showing enhanced degradation efficiency compared to individual strains. Single-species degradation yielded 28.6% weight loss of MP for <i>P. aeruginosa</i>, 12% for <i>B. subtilis</i>, and 16% for <i>L. plantarum</i>. Dual-species models achieved 49% weight loss in <i>P. aeruginosa</i> and <i>B. subtilis</i>, 32% in <i>B. subtilis</i> and <i>L. plantarum</i>, and 20% in <i>L. plantarum</i> and <i>P. aeruginosa</i>, indicating higher polymer breakdown in the dual-species model. FTIR spectra revealed chemical modifications indicative of polymer oxidation, increased transmittance, e.g., 2978 cm⁻¹ (C–H alkane, up to 101%), 1735 cm⁻¹ (C=O carbonyl), 3657 cm⁻¹ (O–H), new peaks like 1450 cm⁻¹ (C–H bend). SEM imaging confirmed microbial colonisation, biofilm formation, and structural deterioration of PPMP surfaces. GC–MS analysis identified degradation byproducts, including monomers, acids, esters, and additives, confirming microbial catabolism of PPMPs.

There have been a limited number of investigations into phytotoxicity, phytoremediation, and the mechanisms of thorium absorption by woody plants. The purpose of this review is to assess the impact of thorium on soil's physical, chemical, and biological characteristics and quantify how much thorium is available for woody plant uptake and how much thorium will be moved around within different parts of the plant. This review also examines the bioavailability, mobility and root uptake of thorium by woody plants. The extent to which woody plants absorb thorium has been reviewed according to three activity concentration rates: low, moderate and high. Furthermore, literature was reviewed and analyzed as to how woody plant absorption may be influenced by having elevated quantities of thorium in the soil, which exceeds the toxic threshold. Thorium adversely affects all living things through hindering seed germination, reducing plant growth, inhibiting photosynthetic rate, and reducing the plants’ ability to absorb nutrients; thorium has not been demonstrated to have any biological function. Woody Plants can employ several methods to combat the negative effects of thorium, such as producing phytochelatins, utilizing multiple compartments for storing thorium, and producing many different types of enzymes that function as antioxidants. Therefore, there are numerous technologically based and microbially based methods available for remediating thorium-contaminated soils, one of which is the use of specific plant species as remedial agents. Finally, a thorough review of literature was performed to identify all native woody plants that are best adapted for phytoremediation of thorium-contaminated soils and the mechanisms used by these native woody plant species to protect themselves from the toxic effects of thorium contamination were determined.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"37 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148434646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gaps in the literature and future research directions were also highlighted. We conducted a systematic review and synthesize information from articles published from 2005 to February 2026. Our results documented 26 types of metal waste generated from mining across SSA, with heavy metals predominating (87.4%). Notably, members of the <i>Bacillus</i> and <i>Pseudomonas</i> genera were prevalent across multiple metals, highlighting their functional redundancy and multiple bioremediation mechanisms in response to metal stress. The bacteria associated with Pb and Cd showed a high Pairwise Jaccard similarity index (0.78). The most frequently reported driving factors of bacterial bioremediation included environmental factors, metal chemistry, bacterial genetic and molecular resistance, with certain bacteria demonstrating high metal removal efficiencies under laboratory conditions. Despite these useful findings, this systematic review identified a restricted geographical scope among the studies and limited field-based application, which may limit our understanding of the field application of bacterial bioremediation of metal waste across SSA. However, diverse and indigenous bacterial microbiomes adapted to complex regional conditions present the opportunities to advance bacterial bioremediation through the integration of emerging techniques such as microbial-assisted phytoremediation, nanotechnology and genetic modification.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"37 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148434759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isolates were primarily screened for the production of PET degradation enzymes qualitatively and quantitatively. Among the screened isolates, PPS3 showed the highest PET fabric waste degradation efficiency of 13.6 ± 1.31% in quantitative screening. Based on 18S rRNA partial gene sequencing, this potent isolate was identified as <i>Aspergillus niger</i> and was utilized for further optimization and degradation experiments. Bioprocess variables influencing fungal lipase enzyme production were optimized through ‘One-factor-at-a-time’ (OFAT) approach. The optimized lipase production media was inoculated with the potent fungal isolate along with the PET waste and kept for 10 weeks of incubation. A weight loss of approximately 55 ± 2.38% was recorded, corresponding to the reduction in PET substrate mass, which demonstrates the degradation potential of the lipase enzyme. The PET degradation potential of the selected isolate was assessed through surface morphology changes (FESEM), and functional group modification (FTIR).
