Synthesis, morphological analysis, antibacterial activity of iron oxide nanoparticles and the cytotoxic effect on lung cancer cell line.

Focusing on the huge importance associated in developing functional materials, this research study describes the synthesis, characterization of morphology, bactericidal activity and cytotoxic effect of iron oxide nanoparticles (IONPs). IONPs have been successfully fabricated through thermal decomposition of a diiron(III) complex precursor. The morphology of the nanoparticle has been delineated with different spectroscopic and analytic methods.

Streptomyces diastaticus isolated from the marine crustacean Portunus sanguinolentus with potential antibiofilm activity against Candida albicans.

Biofilm-mediated multidrug resistance has turned into major challenge for the treatment of C. albicans infections. In the present study, actinomycetes (SS5) isolated from marine crustacean were investigated for their ability to inhibit C.

The cell aggregating propensity of probiotic actinobacterial isolates: isolation and characterization of the aggregation inducing peptide pheromone.

The auto-aggregating ability of a probiotic is a prerequisite for colonization and protection of the gastrointestinal tract, whereas co-aggregation provides a close interaction with pathogenic bacteria. Peptide pheromone mediated signaling has been studied in several systems. However, it has not yet been explored in prokaryotes, especially actinobacteria.

In vitro probiotic profile based selection of indigenous actinobacterial probiont Streptomyces sp. JD9 for enhanced broiler production.

The present study was undertaken to select exclusive indigenous actinobacterial probiont for broiler health improvement based on in vitro probiotic potentials. In total, 18 actinobacterial cultures isolated from chicken were screened for survivability (resistance to low pH, pepsin, bile and pancreatin), colonization (auto-aggregation, hydrophobicity and co-aggregation) and safety (antibiotic susceptibility and non-haemolytic activity). Ten cultures showed excellent viability at pH 2 and most of the acid-tolerant isolates exhibited resistance to pepsin (3 mg/mL), bile (0.
