Indoor formaldehyde (HCHO) exceeding the recommended level, is harmful to human health. The goal of this study was test performance a novel haloalkaliphilic (HAP) Salipaludibacillus agaradhaerens strain NRC-R isolated from hypersaline soda lakes and immobilized in alginate-PVA-chitosan gel composite biodegrade HCHO gas stream air containing various inlet concentrations (0.7 ppm 7 ppm) laboratory scale. surface images cells/beads were examined by scanning electron microscopy (SEM). maximum efficiency removal almost 90% with an loading concentration 0.7 ppm. Stepwise 10 times augment (7 showed that able control very high removed about 60% over 72 h treatment. Although several studies have been reported on isolation HAP bacteria environments, but our knowledge, first report immobilization highly HCHO-controlled bacterial Egypt. This bio-system has biodegradation capacity via pollutant even higher ppm). It assumed S. could be utilized remediation pollutants. Furthermore, strategy may considered employing such as biotechnological treatment technique reduces environmental pollution rate might useful other organic compound pollutants many industrial fields.
