Synthesis of nanoparticles by fungi. Throughout human history, fungi have been utilized as a source of food and harnessed to ferment and preserve foods and beverages. In the 20th century, humans have learned to harness fungi to protect human health ( antibiotics, anti-cholesterol statins, and immunosuppressive agents), while industry has ...
Growth inhibition and death of fungi, bacteria, and yeasts have been seen from chitosan. The antimicrobial effect of chitosan is greater on fungi than yeasts and more effective on gram-negative bacteria than gram-positive bacteria. [1] Poly-ε-lysine is a biodegradable, nontoxic, edible antimicrobial polymer. [1]
Chitosan proves to be effective against bacteria, viruses, and fungi, however it is more effective against fungi and viruses than bacteria. The positively charged chitosan nanoparticles interact with the negatively charged cell membrane, which causes an increase in membrane permeability and eventually the intracellular components leak and rupture.
Methicillin-resistant Staphylococcus aureus (MRSA) is a dangerous bacteria strain because it is resistant to beta-lactam antibiotics. [33] [34] Recent strains of the bacteria, EMRSA-15 and EMRSA-16, are highly transmissible and durable. This is of extreme importance to those concerned with reducing the incidence of hospital-acquired MRSA ...
Some advantages of aPDT in oral infections include broad-spectrum action since aPDT can target a wide range of microorganisms (e.g. bacteria, fungi, and virus), including antibiotic-resistant strains, and oral biofilm is composed of wide variety of microorganisms. Another advantage is the localized treatment that can be used to target specific ...
Deinococcus radiodurans. Brooks & Murray, 1981. Look up Deinococcus or radiodurans in Wiktionary, the free dictionary. Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile.
Antimicrobial. An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi.
The resistance was increased due to the crosslinking of AX via ferulic acid and resulting in a strong AX and gluten network. Although laccase is known to crosslink AX, under the microscope it was found that the laccase also acted on the flour proteins.
