A green and low-cost removal method for cyanate, a toxic byproduct from the treatment of cyanide, is still needed. Cyanase converts cyanate to CO2 NH3, but its industrial practicality limited because reaction requires HCO3− as substrate. In this study, we used carbonic anhydrase Sulfurihydrogenibium azorense (SazCA) provide cyanase Thermomyces lanuginosus (TlCyn); both TlCyn SazCA were purified...

Introdução: A suplementação com bicarbonato de sódio (NaHCO3) tem demonstrado reduzir acidose metabólica e otimizar a performance em exercícios predominantemente anaeróbios; porém, seus efeitos sobre majoritariamente aeróbios são inconclusivos. Objetivo: Avaliar da NaHCO3 corredores rua. Métodos: 14 foram randomicamente distribuídos grupo placebo (PLA = 7; 2 doses 5 g/dia por 27 dias, uma dose ...

The objective of this study was to evaluate the effect of ambient temperature and sodium bicarbonate (NaHCO3) supplementation in diets for growing lambs on meat fatty acids composition. A slaughter study was carried out on 12 male Black Belly Barbados lambs randomly drawn from a prior growth trial (245 days). The lambs were divided into four equal groups and allotted in a 2×2 factorial design. ...

conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...

We tested the hypothesis that ingestion of sodium bicarbonate (NaHCO3) prior to an acute session of high-intensity interval training (HIIT) would augment signaling cascades and gene expression linked to mitochondrial biogenesis in human skeletal muscle. On two occasions separated by ∼1 wk, nine men (mean ± SD: age 22 ± 2 yr, weight 78 ± 13 kg, V̇O(2 peak) 48 ± 8 ml·kg(-1)·min(-1)) performed 10 ×...

BACKGROUND AND OBJECTIVES Metabolic acidosis contributes to muscle breakdown in patients with CKD, but whether its treatment improves functional outcomes is unknown. The choice of dose and tolerability of high doses remain unclear. In CKD patients with mild acidosis, this study evaluated the dose-response relationship of alkali with serum bicarbonate, its side effect profile, and its effect on ...

This paper examines the time course of changes in plasma electrolyte and acid-base composition in response to NaHCO3 and KHCO3 ingestion. It was hypothesized that skeletal muscle is involved in the correction of the ensuing plasma disturbance by exchanging ions, gasses, and fluids between cells and extracellular fluids. Five male subjects, with catheters in a brachial artery and antecubital vei...
