Betaine Improves Polymer-Grade D-Lactic Acid Production by Sporolactobacillus inulinus Using Ammonia as Green Neutralizer.
The traditional CaCO3-based fermentation process generates huge amount of insoluble CaSO4 waste. To solve this problem, we have developed an efficient and green D-lactic acid fermentation process by using ammonia as neutralizer. The 106.7 g/L of D-lactic acid production and 0.89 g per g of consumed sugar were obtained by Sporolactobacillus inulinus CASD with a high optical purity of 99.7% by ad...
متن کاملAmmonia production by intestinal bacteria.
Bacterial growth and the production of ammonia from urea and by deamination of peptone has been examined at various pHs in both conventional static bacterial cultures and in a continuous cultivation system. Growth occurred on primary testing of 93 out of 100 strains of aerobic Gram-negative bacteria at pH 5, and 48 out of 50 strains of Esch. coli at pH 4.6. Hydrolysis of urea by Proteus mirabil...
متن کاملQuantitative Range of Nessler's Reaction with Ammonia.
There is considerable variation in ways of preparing Nessler’s reagent as well as in the manner of forming the colored ammonobasic mercuric iodide. Two critical values are the ratio of KI to Hg19, i.e., x in HgL.xKI, and the final concentration of mercury. The value x determines the stability of solutions and to some extent the relative sensitivity to NH3. Vanselow (2) concluded that x should b...
متن کاملElectrochemical ammonia production on molybdenum nitride nanoclusters.
Theoretical investigations of electrochemical production of ammonia at ambient temperature and pressure on nitrogen covered molybdenum nanoparticles are presented. Density functional theory calculations are used in combination with the computational hydrogen electrode approach to calculate the free energy profile for electrochemical protonation of N2 and N adatoms on cuboctahedral Mo13 nanopart...
متن کاملLatest developments in ammonia production technology
Many Indian ammonia plants struggle with high feedstock prices. In order to survive in the competition from new plants in areas with low gas cost, many plant owners of existing plants have decided to revamp their plants to reduce the energy consumption and/or increase the capacity. New developments are needed in order to fulfil these needs of the market. This paper will highlight some of the de...
