Abstract:
A wireless communication device and the method thereof are disclosed. The wireless communication device in accordance with the present invention includes an integrated protocol layer supporting a first communication protocol and a second communication protocol; a single transceiver operative to transmit and receive signals of said first and said second communication protocols.
Abstract:
The present invention provides an antimicrobial peptide, monodoncin, which is isolated and purified from Penaeus monodon and is capable of being mass produced by molecular cloning techniques in a heterologous expression system, such as yeast. Monodoncin demonstrates a wide-range of bacteriostatic and bactericidal effects on G (−) and G (+) bacteria as well as fungicidal activities, and can be used in combination with conventional antibiotics as “cocktail therapy” to improve the therapeutic effects of the conventional antibiotics.
Abstract:
Surfactin is produced from Bacillus subtilis ssp. containing sfp gene (lipopeptide biosurfactants produced by fermentation). Production of surfactin at present is mainly by liquid fermentation, but the production costs are high due to difficulty in purification resulted from addition of the defoaming agent during the production process. Therefore, present invention conducts physical or chemical mutation on Bacillus subtilis subsp. isolated from Thailand seawater shrimp ponds and screens for the mutant strain of Bacillus subtilis subsp. based on sfp gene expression and then produces surfactin from the mutant strain by semi-solid state fermentation.
Abstract:
Surfactin is a biosurfactant produced by Bacillus subtilis and is a natural cycloaliphatic peptide having a ring structure made of 7 amino acids. The surfactin has various functions including anti-aging, anti-wrinkle, increasing skin penetration of cosmetic products (skin penetration agent), foaming agent, and emulsifier.
Abstract:
A multi-gateway system is disclosed. The multi-gate system may include an access point associated with a zone, the access point providing a network coverage within the zone; a wireless client adapted to communicate with the access point when the wireless client is in the zone; and a virtual central processing device associated with a virtual media access control (MAC) address, wherein the virtual central processing device communicates with the access point to redirect a data packet between the wireless client and a destination.
