Abstract The optimum condition at which the halophilic salt-tolerant bacterium Halomonas variabilis (MTCC 3712) produces the maximum amount of extracellular polymeric substances (EPS) was investigated experimentally using response surface methodology based on the central composite design (CCD). Hyper-saline medium containing 1.5% w/v NaCl enriched nutrient medium with 1.5% glucose as a carbon source was used to produce about 4.74 g/L of EPS in 16 h compared to various other EPS production of this kind. The metabolic heat profile confirms net EPS production by HV was a growth-associated aerobic process. There is a good agreement between metabolic heat and Oxygen Uptake Rate (OUR). The maximum observed heat release was 2.1 W. The total protein content of the sample is 53% of the total EPS (Soluble EPS, Loosely bound EPS, and tightly bound EPS). The emulsifying and flocculating activities of the EPS were measured to explore the possibility of using the biopolymer for effluent treatment.

The article presents experimental study results of the deformation state of composite cable space frame structures, including composite steel-concrete structures. Composite cable space frame structures are three-dimensional roof framing of long-span buildings. The designed constructions are a new type of roof framing structures and consist of typical composite steel-concrete modules connected with steel cable elements. The operation of composite cable space frame structures under load is characterised by geometric nonlinearity. The aim of the research is to study the deformation state and changing the geometric shape of experimental structures under the influence of external load. The technique of studying the deformation state of the composite cable space frame structures is based on the principles of digital photogrammetry. At the limit state the composite cable space frame structures change their regular shape. In this case, the central vertical points get the greatest vertical displacements, and the displacement value decreases closer to the supports. It is defined that the investigated construction has demonstrated combined action of all its components during the test, which indicates its effectiveness. The application of the photogrammetry method made possible to determine the moment of reaching the limit state of the composite cable space frame structures concretely.
