Feather degradation potential of Stenotrophomonasmaltophilia KB13 and feather protein hydrolysate (FPH) mediated reduction of hexavalent chromium
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...
متن کاملReduction of Hexavalent Chromium and Detection of Chromate Reductase (ChrR) in Stenotrophomonas maltophilia.
An Gram negative strain of S. maltophilia, indigenous to environments contaminated by Cr(VI) and identified by biochemical methods and 16S rRNA gene analysis, reduced chromate by 100%, 98-99% and 92% at concentrations in the 10-70, 80-300, and 500 mg/L range, respectively at pH 7 and temperature 37 °C. Increasing concentrations of Cr(VI) in the medium lowered the growth rate but could not be di...

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...
متن کاملNEW NKSMg FERTILIZER FROM FEATHER HYDROLYSATE: POT EXPERIMENTS
EXTENDED ABSTRACT The method of new NKSMg fertilizer based on utilization of feather waste from slaughterhouses was presented. The method allows the production of liquid fertilizers which can be used in soil and foliar application. The whole process is based on the digestion of feather waste by acid hydrolysis, adjusting pH of the reaction medium, and then enriched in selected nutrients. Pot ex...
متن کاملScreening of fungi efficient in feather degradation and keratinase production
Two hundred thirty four fungal strains were isolated by baiting method, for their feather degradation and keratinase producing ability. Fungi were tested on solid milk agar plates and in submerged culture. Maximum clearing zone was made by Chrysosporium indicum (7mm) on solid agar plates. The highest keratinase production was found in case of Acremonium strictum (74.40Unit/mL & 124.72 Unit/ml i...
