Title: Hydrolytic fermentation method for lignocellulose biomass raw material
Inventor: SHAO XIONGJUN
IPC: C12P7/56
Filed: 2019-08-06
Abstract: Disclosed is a hydrolytic fermentation method for a lignocellulose biomass raw material. The method comprises the following steps: using one or more fungi of the self-produced cellulase and/or hemicellulase to ferment the lignocellulose biomass raw material; adding the lignocellulose biomass raw material into a fermentation liquor, and adding one or more fungi of cellulase, hemicellulase, the self-produced cellulase and/or hemicellulase for hydrolysis or hydrolytic fermentation to obtain a bio-based product. The method firstly uses cellulase and hemicellulase self-excreted by the fungi to perform hydrolytic fermentation on some of the lignocellulose biomass raw material, and then uses the fungi of cellulase, hemicellulase, the self-produced cellulase and/or hemicellulase to perform hydrolysis or hydrolytic fermentation on more lignocellulose biomass raw material. Compared with the prior art, the amount of cellulase, hemicellulase, etc. needed by the method for processing the same amount of the lignocellulose biomass raw material is remarkably reduced, thereby effectively reducing the cost and having a higher cellulose hydrolysis rate.

Title: Communication method and apparatus
Inventor: YOU CHUNHUA
IPC: H04W52/02
Filed: 2019-12-30
Abstract: In order to improve transmission efficiency when a configuration grant is used for transmission, provided is a communication method. In this method, a terminal receives a configuration parameter from a network device, the configuration parameter being used for indicating a timer duration, and the timer duration being a minimum duration before a terminal expects to receive downlink feedback information. The terminal performs configuration grant transmission on a first hybrid automatic repeat request (HARQ) process, and starts a first timer of the first HARQ process in response to the configuration grant transmission, the first timer comprising the timer duration indicated by the configuration parameter. Because the first timer of one HARQ process is started in response to the configuration grant transmission, after the minimum duration which is between a time point after the uplink transmission to a time point before the terminal expects to receive the downlink feedback information, it is probable for a feedback for the configuration grant transmission to arrive. Therefore, if a feedback of the HARQ process is received during the operation of the timer, it is indicated that the feedback is invalid. Therefore, the terminal can determine whether the feedback is valid on this basis, thereby reducing the possibility of erroneous determination of the feedback and improving communication efficiency.
