For a long time, the main interest in marine environment, considered extreme, was isolation and identification of natural products with biological properties, for that, numerous organisms chemical structures have been studied. Thus, bacteria isolated from various substrates, such as sediments, seawater, mangrove detritus, are producers enzymes different activities, i.e., amylase, cellulase, alg...

An efficient keratinolytic strain of Stenorophomonas maltophilia KB13 was isolated from feather disposal site of Bilaspur, Chhattisgarh, India. The strain could metabolize 10 g/l chicken feathers as sole source of carbon and nitrogen. Soluble protein, amino acid, and cysteine content were found to be maximum (690.6 ± 8.7, 688.9 ± 9.12 and 21 ± 0.36 µg/ml, respectively) at late logarithmic phase...
