Post-acidification of fermented milk and its molecular regulatory mechanism.
Journal of food microbiologyThe fermented milk products with lactic acid bacteria (LAB) are widely accepted by consumers. During the chilled-chain transportation and storage, LAB in the product keep producing lactic acid, and this will lead to post-acidification, which can affect ...

Acidification of Lactose in Wastewater
Journal of Environmental Engineering, 2001Acidification of lactose in wastewater was conducted in four series of experiments in an upflow reactor to investigate individual effects of hydraulic retention time (HRT) (2–24 h), lactose concentration in wastewater (2–30 g COD/L), pH (4.0–6.5), and temperature (20°–60°C). Optimum acidification was found at pH 5.5 and 55°C.

Urinary acidification in children
Clinica Chimica Acta, 1968Abstract Eleven children with normal renal function between the ages of 4–14 and with body surface area between 0.60–1.43 m2 were subjected to a short-term test of urinary acidification. Urine specimens were collected 2 hourly before and after 8 h of the oral administration of ammonium chloride, 0.1 g/kg body weight.

Metals and Acidification: An Overview
Water, Air, & Soil Pollution, 1986Both upland soils and lake sediments appear to retain atmospherically deposited trace metals (e.g. Pb) even under acid conditions. The abundant, local, mineralogically derived metals (e.g. Al and Mn) are exported from upland soils under acidic conditions, but are usually retained by lake sediments.

Spatial aspects affecting acidification factors in European acidification modelling
Environmental Modelling & Software, 2009Plain linear models have recently been used in methodologies to model fate and transport for assessing acidification in life cycle impact assessment (LCIA), or in support of air pollution abatement policies. These models originate from a statistical analysis of the relationship between inputs and outputs of physically-based models that reflect the ...

Acidification and polymerization of actin
Biochimica et Biophysica Acta, 1952Abstract The production of H-ion when salt is added to actin solution appears to be the usual effect of salt upon a protein solution and not to be prerequisite for polymerization. The pH decreases immediately after the salt is added but polymerization, as judged by changes in viscosity, does not begin for one to three minutes.

Soil Acidification and Alkalinization
1991In this chapter I briefly discuss the nature of soil acidification and alkalinization, and define these processes in terms of changes in the relevant capacity factors. Next, the contribution of various sources of soil acidification and their quantitative importance is treated in some detail: (1) effects of addition of acids or bases by irrigation and ...

Acidification of animal slurry– a review
Journal of Environmental Management, 2015Ammonia emissions are a major problem associated with animal slurry management, and solutions to overcome this problem are required worldwide by farmers and stakeholders. An obvious way to minimize ammonia emissions from slurry is to decrease slurry pH by addition of acids or other substances.
