The Architecture of Degradative Complex Polysaccharide Enzyme Arrays in a Marine Bacterium Has Implications for Bioremediation

As human population pressures build and more food is required, agricultural (Bayer & Lamed, 1992), aquacultural (Gomez-Pinchetti & Garcia-Reina, 1993), and algalcultural (Powell & Weiner, 1993) wastes threaten to become an increasingly serious problem. The wastes are mostly recalcitrant insoluble complex polysaccharides (ICP), namely cellulose, chitin, and often agar, respectively. These ICP are composed of monosaccharides, many of which can provide valuable feedstock when hydrolyzed. Indeed, in developing nations, this sort of reclamation is becoming progressively important. Unidentified autochthonous microbiota degrade and recycle shrimp, algal and other mariculture wastes in Asia (Ajisaka & Chiang, 1993) and South America (Punja & Zhang, 1993). These technologies have historically moved from the utilization of ìwild populationsî to carefully controlled, tamed specialists. In brewing and other endeavors, the gain in reliability, efficiency and control have been dramatic. Aqua-, algal- and agri-cultural practices are now in this transition (Doi et al., 1994).
