Abstract: Microalgae are potential energy resources for production of biofuels, such as biodiesel, ethanol, and butanol. A method for enhancing cell growth of microalgae enhances transgenic expression of a bicarbonate transporter (HCO3? transporter) in microalgae and thereby obtains a genetically modified microalgae capable of enhanced inorganic carbon fixation, efficient photosynthesis, and expeditious cell growth. The genetically modified microalgae are fit for use in biofuel production.

Abstract: A system and method for protecting data of network users are provided. A user end device is connected to a routing device. Then, the routing device directs data packets of the user end device into a data protection device connected to the routing device in series, according to profiles corresponding to the user end device. Security services are performed on the received data packets by the data protection device, thereby providing effective data security protection services to network users and overcoming the drawbacks of high costs and high maintenance required for self-configuration of such mechanisms in prior techniques.

Abstract: A system and method for identifying a network-connected user are disclosed. The method includes connecting a user end device to a routing device and guiding the user end device to a specific routing path by the routing device according to a programmed file of the user end device, thereby overcoming the drawbacks of prior techniques in which routing devices configured by ISPs can only forward data packets based on IP addresses and a routing table, being unable to make routing orientations according to characteristics of the data packets. The present invention facilitates management of data packets of specific network users and can provide more flexible combinations of service content.
