Solar photoactive magnesium substituted copper ferrite photocatalysts for Rose Bengal treatment Raghu, Anjanapura V In the present investigation, we have reported solar photo active, cost effective and magnetically recoverable magnesium substituted copper ferrites successfully prepared by simple co-precipitation method. The prepared materials were characterized for structural and microstructural analysis using PXRD, SEM, EDS, FT-IR and UV–Visible spectroscopy. It was observed that, when copper introduces into magnesium ferrite system light absorption shifted to visible region, this is due to formation of metastable energy levels just below the conduction band of magnesium ferrites. As a result an MgCuFe2O4 catalyst exhibits excellent efficiency under solar light irradiation. These catalysts are stable for longer period even after many runs and magnetically separable. Based on the analysis result these nanomaterials can be used as potential environmental and energy applications under natural sunlight irradiation.

Harnessing Symbiotic Association of Lactic Acid Bacteria and Cellulose-Synthesizing Bacteria for Enhanced Biological Activity Ali Jawad Akki, Lavanya D. Hiremath.; Raghavendra Rao Badkillaya Bacterial cellulose (BC) is an extremely pure and highly valuable biomaterial. However, its production cost poses a challenge for large-scale manufacturing. This study explores a cost-effective approach by co-cultivating lactic acid bacteria with cellulose-synthesizing bacteria. Four BC-producing isolates from spoiled fruits and four lactic acid bacteria from fermented buttermilk were isolated and characterized. Growth studies demonstrated successful lactic acid bacteria cultivation in HS media. Co-cultivation of cellulose-synthesizing bacteria and lactic acid bacteria showed enhanced BC production, with a twofold increase in dry weight (0.35 g/150 ml) compared to the monoculture of cellulose-synthesizing bacteria (0.15 g/150 ml). Scanning electron microscopy revealed improved BC microfibril quality in co-culture. Reversed-phase HPLC confirmed higher lactic acid concentrations in co-culture. 16S rRNA sequence analysis revealed that lactic acid bacteria had a 100% match with Lactococcus lactis. These findings highlight the potential of co-cultivation for cost-effective BC production and lactic acid yield, offering a sustainable approach to biomaterial production. © 2024, The Author(s), under exclusive licence to Shiraz University.

Microbial biotechnology alchemy: Transforming bacterial cellulose into sensing disease- A review Akki, Anjanapura, V Raghu Ali Jawad Biosensors have the potential to revolutionize healthcare by providing rapid and accurate diagnosis of diseases. Biosensors are analytical devices that convert molecular recognition of a target analyte into a measurable signal. Older diagnostic techniques, such as immunoaffinity column assays, fluorometric, and enzyme-linked immunosorbent assays, are laborious, require qualified personnel, and can be time consuming. In contrast, biosensors offer improved accuracy, sustainability, and rapidness due to their ability to detect specific biomarkers with high sensitivity and specificity. The review covers various bacterial cellulose (BC)-based biosensors, from SARS-CoV-2 detection to wearable health monitoring and interaction with human-computer interfaces. BC's integration into ionic thermoelectric hydrogels for wearable health monitoring shows its potential for real-time health tracking. Incorporating BC in biosensors for low-noise electrodes, and wearable sensors has been elaborated. The invention of a phage-immobilized BC biosensor for S. aureus detection is a significant contribution to the field, highlighting the biosafety and efficiency of BC in pathogen identification and demonstrating BC's versatility across multiple sensing platforms. Palladium nanoparticle-bacterial cellulose hybrid nanofibers show excellent electrocatalytic activity for dopamine detection, whereas Au-BC nanocomposite biosensors show efficacy in glucose detection, with potential therapeutic applications. The “lab-on-nanopaper” device, utilizing BC nanopaper, not only visually detects human serum albumin but also establishes itself as a new-generation optical biosensing platform with superiority over conventional substrates. This review contributes to the ongoing advancements in biosensor technology, highlighting the potential of BC as a versatile material for developing innovative biosensors. This is crucial for improving the accuracy, sensitivity, and efficiency of diagnostic tools in healthcare. © 2024 The Authors
