<p>In this review, we describe recent developments and strategies involved in the utilization of solid supports for management wastewater by means biological treatments. The origin determines whether it is considered natural or industrial waste, source(s) singly collectively contribute to increase water pollution. Pollution a threat aquatic humans; thus, before discharge treated waters back into environment, put through number treatment processes ensure its safety human use. Biological bioremediation has become increasingly popular due positive impact on ecosystem, high level productivity, process application cost-effectiveness. Bioremediation involving use microbial cell immobilization demonstrated enhanced effectiveness compared free cells. This constitutes significant departure from traditional practices (entrapment, adsorption, encapsulation), addition ability engage covalent bonding cross-linking. Thus, took comparative look at existing emerging methods related challenges, focusing future. Furthermore, our work stands out highlighting state-of-the-art tools that are bioinspired [enzymes, reactive permeable barriers linked electrokinetic, magnetic cross-linked enzyme aggregates (CLEAs), bio-coated films, microbiocenosis], as well nanosized biochar engineered cells their bioproducts targeted enhancing removal efficiency metals, carbonates, organic matter, other toxicants pollutants. potential integration 'omics' technologies revealing new insights via also discussed.</p>

Maize Bran Arabinoxylans Mediated Green Synthesis of Silver Nanoparticles and Their Incorporation in Gelatin-Based Packaging Film

Опубликована: Янв. 1, 2023

The current research aimed to extract arabinoxylans from maize bran (MBAXs), synthesis of silver nanoparticles (AgNPs) through MBAXs, their characterization, and in-vitro efficacy against S. aureus E.coli. Then, AgNPs were loaded in gelatin-based biofilm different concentrations (0, 0.5, 1, 1.5%). Results showed that MBAXs contained arabinose (25.83%), xylose (32.12%) higher proportion. XRD was amorphous whereas, capped observed with crystalline spectra presented the face-centered cubic structure. Moreover, SEM micrographs spherical irregular structure AgNPs. Further, an inhibition zone range 7.38-13.78 mm 11.45-19.14 E. coli respectively. FTIR stretchings at 3270, 2935, 1625, 1542, 1030 cm-1 which presence –OH, -CH, N-H groups gelatin. Increase concentration, imparted minor changes, on surface film. gelatin addition didn’t affect thickness biofilms but affected mechanical properties after exceeding 0.5%. In conclusion, are suitable formation a prominent antimicrobial activity incorporation concentration dependent manner, for intelligent packaging, will be way forward towards sustainability.
