摘要

细菌产生色素来保护自己免受紫外线辐射和氧化损伤，帮助它们在各种环境中生存和适应。随着人们对合成染料的关注，微生物色素因其潜在的好处而受到关注。它们具有产量高、成本效益高、提取方便等优点。从辣木根茎土壤中分离得到的硬木链霉菌可产生粉红色/品红色素。采用紫外-可见分光光度、红外光谱、高效液相色谱、核磁共振等方法对其进行表征。分离得到的MSS色素对大肠杆菌、伤寒沙门氏菌、肺炎克雷伯菌、耳念珠菌和白色念珠菌等细菌和真菌均无抑菌活性。此外，它没有溶血活性，表明其在各种应用中的潜在安全性。重要的是，这种色素在纺织品染色中表现出持久的保留力（即使经过多次洗涤），并且在唇膏配方中稳定地掺入，突出了它作为合成染料的安全和环保替代品的潜力。这项研究强调了微生物色素在各种工业应用中的前景，提供了一种可持续和环保的解决方案。

Characterization and applications of MSS pigment isolated from Streptomyces ardesiacus

Bacteria produce pigments to protect themselves from UV radiation and oxidative damage, aiding their survival and adaptation in various environments. As concerns over synthetic dyes grow, microbial pigments have gained attention for their potential benefits. They offer advantages such as high yield, cost-effectiveness, and ease of extraction. Streptomyces ardesiacus, isolated from Moringa olifera rhizophore soil produced pink/magenta colour pigment. It was characterized by UV–Vis spectrophotometry, FT-IR, HPLC, and NMR. The isolated MSS pigment showed no antimicrobial activity against tested bacterial and fungal strains, including Escherichia coli, Salmonella typhi, Klebsiella pneumoniae, Candida auris and Candida albicans. Moreover, it showed no haemolytic activity, indicating its potential safety for use in various applications. Importantly, the pigment demonstrated durable retention in textile dyeing (even after multiple washes) and stable incorporation in lip balm formulation, highlighting its potential as a safe and eco-friendly alternative to synthetic dyes. This study underscores the promise of microbial pigments in various industrial applications, offering a sustainable and eco-friendly solution.

期刊介绍： The Journal of Microbiological Methods publishes scholarly and original articles, notes and review articles. These articles must include novel and/or state-of-the-art methods, or significant improvements to existing methods. Novel and innovative applications of current methods that are validated and useful will also be published. JMM strives for scholarship, innovation and excellence. This demands scientific rigour, the best available methods and technologies, correctly replicated experiments/tests, the inclusion of proper controls, calibrations, and the correct statistical analysis. The presentation of the data must support the interpretation of the method/approach. All aspects of microbiology are covered, except virology. These include agricultural microbiology, applied and environmental microbiology, bioassays, bioinformatics, biotechnology, biochemical microbiology, clinical microbiology, diagnostics, food monitoring and quality control microbiology, microbial genetics and genomics, geomicrobiology, microbiome methods regardless of habitat, high through-put sequencing methods and analysis, microbial pathogenesis and host responses, metabolomics, metagenomics, metaproteomics, microbial ecology and diversity, microbial physiology, microbial ultra-structure, microscopic and imaging methods, molecular microbiology, mycology, novel mathematical microbiology and modelling, parasitology, plant-microbe interactions, protein markers/profiles, proteomics, pyrosequencing, public health microbiology, radioisotopes applied to microbiology, robotics applied to microbiological methods,rumen microbiology, microbiological methods for space missions and extreme environments, sampling methods and samplers, soil and sediment microbiology, transcriptomics, veterinary microbiology, sero-diagnostics and typing/identification.
