Abstract A laboratory bench-scale study using a unified anaerobic fermenter-filter system (referred to as a BVF-HAF system) was conducted at room temperature over an 8 month period on potato processing wastewater for the purpose of verifying a proposed full-scale design concept. In addition to two-stage anaerobic treatment, the first stage anaerobic effluent (BVF effluent) was subjected to aerobic polishing in a simulated facultative aerated lagoon with a retention of 4 days. The basic design conditions entailed treatment of a clarified potato wastewater with a COD of 7600 mg/L and a retention of 4 d in the BVF (loading 1.71 kg/m3.d). After over-coming an upset condition believed due to toxicity of the vacuum filtrate feed, the model performed well achieving 78.9% COD removal in the BVF plus 5 3.4% in the HAF for a combined total of 90.2%. When the BVF effluent was aerated the combined BVF - aerated lagoon removal reached 94.8%.

ABSTRACT The human large intestine is covered with a protective mucus coating, which is heavily colonized by complex bacterial populations that are distinct from those in the gut lumen. Little is known of the composition and metabolic activities of these biofilms, although they are likely to play an important role in mucus breakdown. The aims of this study were to determine how intestinal bacteria colonize mucus and to study physiologic and enzymatic factors involved in the destruction of this glycoprotein. Colonization of mucin gels by fecal bacteria was studied in vitro, using a two-stage continuous culture system, simulating conditions of nutrient availability and limitation characteristic of the proximal (vessel 1) and distal (vessel 2) colon. The establishment of bacterial communities in mucin gels was investigated by selective culture methods, scanning electron microscopy, and confocal laser scanning microscopy, in association with fluorescently labeled 16S rRNA oligonucleotide probes. Gel samples were also taken for analysis of mucin-degrading enzymes and measurements of residual mucin sugars. Mucin gels were rapidly colonized by heterogeneous bacterial populations, especially members of the Bacteroides fragilis group, enterobacteria, and clostridia. Intestinal bacterial populations growing on mucin surfaces were shown to be phylogenetically and metabolically distinct from their planktonic counterparts.
