How is cellulose catalyst
WebBacterium cellulose synthesis requires the activation of bcsA, the catalytic subunit of cellulose synthase, through c-di-GMP (Ross et al., 1987). It appears to be a specific type of regulation in bacteria since plants does not have c-di-GMP. WebA novel cellulase-mimetic solid catalyst, sulfonated chloromethyl polystyrene resin (CP-SO 3 H), containing cellulose-binding sites (–Cl) and catalytic sites (–SO 3 H) was …
