Dental disease is a very prevalent and costly disease in which the symptoms, not the disease, are currently being treated. The disease is caused by pathogenic oral bacteria, many of which are a part of the Mutans Streptococci. The objective of this thesis was to find a natural substance that...
Objective: To screen different solvent extracts of Elaeagnus kologa (E. kologa) leaf to determine the phytochemicals, potent antioxidant and antibacterial activity to find out the possible source of applied pharmaceutical formulations.
Methods: Solvent extracts of leaf material were prepared using the Soxhlet apparatus. A study was performed on antioxidant activity...
Endophytes are bacteria or fungi that live within a host plant. The plant host provides a home for endophytes, and in return endophytes produce primary and secondary metabolites, of which many of the secondary metabolites possess biological activities. When microorganisms are grown under various media conditions, they produce different natural...

Antibacterial activities in the salivary glands of
female mosquitoes Aedes aegypti were investigated in this
study.
The mean salivary bacteriolytic activity, during a
period of 14-day of female mosquitoes exposed to five
different concentrations of Gram-positive bacteria
Micrococcus lysodeikticus in the sucrose meal, was
detected by a lysoplate method. A...
Escherichia coli 16S-like ribosomal RNAs from
eubacterial, archaebacterial and eukaryotic organisms have
several universally conserved sequence zones which are
proposed to be single-stranded. A clear function for all
of these regions has not yet been defined. To evaluate the
roles of these sequence zones in protein synthesis,
knowledge of their...
Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...
The discovery of novel compounds with antibacterial properties continues to be critically important.3 One potential source of such compounds is the cryptic genome of fungi known to produce biologically active molecules. A kmt6 mutant of the cereal pathogen Fusarium graminearum was previously developed through a histone H3 lysine 27 methyltransferase...
The objectives of this project were to investigate the critical factors impacting the physicochemical and antibacterial properties of β-chitosan based films derived from jumbo squid (Dosidicus gigas) pens, and to evaluate the feasibility of improving water solubility of β-chitosan through Maillard reaction. The studies examined the effect of molecular weight...
