acid-tolerant

As part of re-greening efforts, 16 million trees have been planted and the basin has been seeded with acid-tolerant grass.

Acidity levels of below pH 4.0 inhibit lactobacilli and favour acid-tolerant yeasts.

However, Clostridium bacteria are less acid-tolerant than Acetobacter.

This would be done by manipulating soil chemistry and using deep-rooted, acid-tolerant rice cultivars to help capture the leached components.

The nineteenth-century microfossil record shows a decline in plant plankton such as flourish in neutral conditions and an increase in acid-tolerant species.

For example, by utilizing acetic acid, the yeast can raise the pH of pickles sufficiently to allow the growth of less acid-tolerant bacteria.

Acidity alone has been questioned by recent outbreaks of food poisoning by E. coli O157:H7 that is acid-tolerant.

It is likely that plaques induce these IgG antibodies from gingival sulci that contain more acid-tolerant bacteria.

Lesser twayblade and heather have already declined on Peak District bogs, while the acid-tolerant cotton-grass and bilberry are now more common.

Acidiphilic and acid-tolerant strains which were initially classified under this genus have later been moved to Kitasatospora (1997) and Streptacidiphilus (2003).

Ecological damage to aquatic and riparian ecosystems through fish kills, increased fish disease outbreaks, dominance of acid-tolerant species, precipitation of iron, etc.

The first description of H. Pylori came in 1892 from Giulio Bizzozero, who identified acid-tolerant bacteria living in a dog's stomach.

In low responders, the fewer antibodies to D-alanyl LTA suggest less colonization by acid-tolerant bacteria and a weaker cariogenic attack.

The shrub layer may be well-developed, with hillside blueberry (Vaccinium pallidum), black huckleberry (Gaylussacia baccata), or other acid-tolerant species most characteristic.

The canning industry works under the assumption that bacterial spores will not germinate at pH values below 4.6, and that acid-tolerant organisms are not very heat resistant.

Instead, addition of naturally acidic Lactobacillus "sourdough" cultures lowers bread pH, provides an acid-tolerant yeast strain, and helps gelatinize starches in the dough matrix.

But the scientists found that the lack of phosphorus will limit production even if calcium is added to the soil to overcome the acidity, or if acid-tolerant cultivars are planted.

The site has already begun to address an issue on the apple industry's horizon: E. coli has mutated an acid-tolerant strain, traces of which have been found in fresh apple cider.

Acid-tolerant bacteria require D-alanyl glycerol lipoteichoic acid (D-alanyl LTA) in their membranes and cell surfaces [ 14 ] .

In Sweden, British species such as dog rose, cowslip and ladies' bedstraw are thought to have been lost from polluted woods, where the nitrogen-loving nettle and acid-tolerant wood sorrel now occur.

Even the most acid-tolerant Clostridium strains can produce vinegar of only a few per cent acetic acid, compared to Acetobacter strains that can produce vinegar of up to 20% acetic acid.

YM Agar and Broth, is a selective growth medium with low pH useful for cultivating yeasts, molds, or other acid-tolerant or acidophilic organisms, while deterring growth of most bacteria and other acid intolerant organisms.

Sourdough (also known as "levain" or "natural leaven") takes the pre-ferment method a step further, mixing flour and water to allow naturally occurring yeast and bacteria to propagate (usually Saccharomyces exiguus, which is more acid-tolerant than S. cerevisiae and various species of Lactobacillus).
