Protease production under solid state fermentation (SSF) was investigated using isolated Aspergillus flavus. Different agroindustrial waste products were evaluated to check the possibility of potential utilization of substrates in SSF for protease production by Aspergillus flavus using wheat bran as a substrate. The results showed that the optimum conditions for maximum protease production were...

We present a detailed study of the structural behavior and polarization reversal mechanism in phase III of KNO3, an unusual ferroelectric material in which the nitrate groups rotate during polarization reversal. This material was one of several studied in a previous work O. Diéguez and D. Vanderbilt, Phys. Rev. Lett. 96, 056401 2006 where methods were described for computing curves of energy ve...

Abstract. The reactivity of NO3 plays an important role in modifying the fate reactive nitrogen species at nighttime. High (e.g. towards unsaturated volatile organic compounds – VOCs) can lead to formation nitrates and secondary aerosol, whereas low opens possibility heterogeneous NOx losses via uptake N2O5 particles. We present direct measurements (kNO3) that quantify VOC-induced during TO2021...

The rhizobial bacteria can be readily grown on a variety of media containing complex nutrient extracts of microbial, mineral, or plant origin, but growth on nonsupplemented carbohydrate-inorganic salts media is poor for most species. Only a minor part of the extensive research devoted to Rhizobium has dealt with the minimum requirements for cultural growth (Wilson, 1940; Wilson and Wilson, 1942...

A new flexible hexakis-fullerene adduct with two bis(pyridin-4-ylmethyl)malonate groups located at trans-1 positions was synthesized. Via reaction with Ag(PF6) under two different conditions, two new 1D coordination polymers were obtained; under a nitrogen atmosphere, the silver ions are connected by argentophilic interactions but under an ambient atmosphere, the silver ions exhibit no interact...

AIM To compare the plaque inhibition efficacy of a sodium fluoride/potassium nitrate (NaF/KNO3 with 1450 ppm F) test dentifrice to a 0.454% stannous fluoride/sodium hexametaphosphate/sodium fluoride positive control dentifrice (SnF2/SHMP with 1450 ppm F). METHODS AND MATERIALS Twenty-five subjects were randomized to a two-period, two-treatment, double blind crossover sequence using NaF/KNO3 (...

Information is meager concering the influence of salts on the metabolic processe of halophiles. In fact, reports of the work of Robinson et al. (1952) are the only recent studies in this field. Robinson (1952) showed that there was an optimum concentration of sodium chloride for maximum activity of lactic acid dehydrogenase. While studying the effect of salt on Micrococcwu halodenifns, Robinson...

Salt-like cluster ions of the ([cation](n)[anion](n-1))(+) type are commonly composed of mono-atomic, inorganic components. Clusters containing organic ions are also known, with nitrogen-centred cations being particularly prominent. However, sulphur-centred analogues, such as organic sulphonium salts, represent a notable exception. Fast atom bombardment and liquid secondary ion mass spectrometr...

While it is well known that ruminants (with the aid of rumen microorganisms) can utilize ammonium salts and urea in lieu of dietary protein,” 2 it has long been held that monogastric animals cannot.’ In view of the findings of Foster, Schoenheimer, and Rittenberg3 that dietary ammonium N15 is rapidly incorporated into rat tissue proteins, it seemed possible that the nitrogen of ammonium salts m...

Plant density was varied with P, Ca, Mg, and KNO3 in a multifactor experiment to improve Curcuma longa L. micropropagation, biomass and microrhizome development in fed-batch liquid culture. The experiment had two paired D-optimal designs, testing sucrose fed-batch and nutrient sucrose fed-batch techniques. When sucrose became depleted, volume was restored to 5% m/v sucrose in 200 ml of modified...
