A strain of sludge-lysing bacteria was isolated from waste activated sludge (WAS) in this study. The result of 16S rRNA gene analysis demonstrated that it was a species of new genus Brevibacillus (named Brevibacillus sp. KH3). The strain could release the protease with molecule weight of about 40 kDa which could enhance the efficiency of sludge thermophilic(More)
The use of two-level intensity signal for interleaved polling with adaptive cycle time (IPACT) in passive optical networks (PONs) is presented. In the scheme, two different optical powers are used by two-grouped optical network units (ONUs) for their OOK modulation formats, and combined through the passive optical coupler on the way to the optical line(More)
