Plackett-Burman design (PBD) was used to evaluate the effect of 11 process variables and studies here showed that phytase production was significantly influenced by glucose, dextrin, distilled water, and MgSO4 center dot 7H(2)O. The use of response surface methodology (RSM) by Box-Behnken design (BBD) of experiments further enhanced the production by a remarkable 36.67-fold from the original finding of 15 IU/gds (grams of dry substrate) to 550 IU/gds. This is the highest solid-state fermentation (SSF) phytase production reported when compared to other microorganisms and in fact betters the best known by a factor of 2. Experiments carried out using dried fermented koji for phosphorus and mineral release and also thermal stability have shown the phytase to be as efficient as the liquid enzyme extract. Also, the enzyme, while exhibiting optimal activity under acidic conditions, was found to have significant activity in a broad range of pH values (1.5-6.5). The studies suggest the suitability of the koji supplemented with phytase produced in an SSF process by the "generally regarded as safe" (GRAS) microorganism A. niger as a cost-effective value-added livestock feed when compared to that obtained by submerged fermentation (SmF).1 aBuddhiwant, Priyanka1 aBhavsar, Kavita1 aKumar, Ravi1 aKhire, Jayant, M.  uhttps://library.ncl.res.in/content/phytase-production-solid-state-fermentation-groundnut-oil-cake-aspergillus-niger-bioprocess02274nas a2200169   4500008004100000245011600041210006900157260000800226300002300234490000600257520163200263100002001895700001601915700002301931700002201954856012801976       2017                        eng d00aPhytase production by aspergillus niger NCIM 563 for a novel application to degrade organophosphorus pesticides0 aPhytase production by aspergillus niger NCIM 563 for a novel app  cMAR  aArticle Number: 660 v73 aThe production of phytase using Aspergillus niger NCIM 563 under submerged fermentation conditions was studied using protein rich chickpea flour as substrate. Employing a hybrid statistical media optimization strategy of Plackett-Burman and Box-Behnken experimental designs in shake-flasks gave an increased phytase activity from an initial 66 IU/mL in 216 h to 160 IU/mL in a reduced time of 132 h. Productivity, thus increased by 3.97 times from 7.3 to 29 IU/mL/day. Using the optimized media, the production was successfully scaled-up further and improved up to 164 IU/mL in 96 h by studies carried out employing 2 and 10-L fermenters. The enzyme supernatant was recovered using centrifugal separation of biomass and the stability of the produced phytase was tested for animal feed applications under gastric conditions. In vitro degradation studies of water soluble monocrotophos, methyl parathion and water insoluble chlorpyrifos, pesticides used extensively in agriculture was carried out. It was observed by HPLC analysis that phytase could degrade 72% of chlorpyrifos at pH 7.0, 35 degrees C. Comparable results were obtained with monocrotophos and methyl parathion. With chlorpyrifos at higher temperature 50 degrees C as much as 91% degradation could be obtained. The degradation of chlorpyrifos was further validated by spraying phytase on harvested green chilli ( Capsicum annuum L) under normal conditions of pH 7.0, 35 degrees C and the degradation products obtained analyzed by LCMS. Thus, the present study brings out a potentially novel application of phytase for biodegradation of organophosphorus pesticides.1 aShah, Parin, C.1 aKumar, Ravi1 aDastager, Syed, G.1 aKhire, Jayant, M.  uhttps://library.ncl.res.in/content/phytase-production-aspergillus-niger-ncim-563-novel-application-degrade-organophosphorus01975nas a2200277   4500008004100000020001400041245012200055210006900177260000800246300001100254490000700265520107900272653001501351653001201366653001701378653002901395100002501424700002901449700002401478700002301502700002901525700002601554700002201580700002301602856007201625       2021                        eng d  a1878-818100aPerformance of Aspergillus niger (NCIM 563) phytase based feed supplement for broiler growth and phosphorus excretion0 aPerformance of Aspergillus niger NCIM 563 phytase based feed sup  cJAN  a1018870 v313 aDespite availability of commercial enzymes, the phytase produced from relatively inexpensive systems with high yields are gaining global attention in the feed industries in post-antibiotic era. We studied A. niger NCIM 563 Phytase produced in solid state fermentation (SSF) derived Koji powder and evaluated its utility in the poultry feed for broiler growth performance and phosphorous (P) excretion. The ability of phytase in the dried powder was estimated to dephytinize the poultry feed under simulated gastric conditions. Poultry feed was formulated using A. niger NCIM 563 phytase followed by a 42 days feed trial on broilers. After supplementation of phytase to the diet, there was a reduction of dietary P, maintained growth performance, skeletal development of broilers and reduced levels of phytic acid and available P in the litter. Extracellular phytase was able to replace up to 0.1% P in poultry feed. Minimal downstream processing a low-cost feed supplement with significant phytase activity could provide added advantage for anti-nutrition free poultry feed.10aPhosphorus10aPhytase10aPoultry feed10aSolid state fermentation1 aPuppala, Kumar, Raja1 aBuddhiwant, Priyanka, G.1 aAgawane, Sachin, B.1 aKadam, Avinash, S.1 aMote, Chandrashekhar, S.1 aLonkar, Vijaysinh, D.1 aKhire, Jayant, M.1 aDharne, Mahesh, S.  uhttps://www.sciencedirect.com/science/article/pii/S1878818120319186
