bacillus sp. guf8, isolated from acidic soil samples of a tea farm was identified as bacillus cereus, based on 16s rdna sequencing and standard bacterial identification methods. following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. consequently, thermostability and kinetic parameters of the purified enzyme wer...

A preliminary in vitro acid neutralizing capacity test of twelve traditional Ayurvedic antacids were performed in this study. Five traditional preparations of ash of conch shell, ash of oyster, ash of pearl, limestone, and ash of cowrie showed high acid neutralizing capacity similar to standard antacid combination of Al(OH) 3 and Mg(OH) 2 . Among these the ash of conch shell found the highest a...

Extreme pHs, especially acidic pHs, are among the environmental stresses that some bacteria face. The most important strategies that bacteria employ for acid adaptation include either production of acidophilic proteins, or raising the pH of the microenvironment by secretion of basic compounds including ammonia produced by the action of urease. Considering the importance of acid-neutralizing bac...

A neutralizing agent combination strategy was developed to enhance the succinic acid production by Actinobacillus succinogenes ATCC 55618. First, a maximal succinic acid production of 48.2 g/L was obtained at a culture pH of 7.5. Second, NaOH and KOH were screened to identify the optimal neutralizing agent for pH control. However, the production of succinic acid did not increase, and severe cel...

Hypersecretion of gastric acid damages the stomach lining, causing formation peptic ulcers. Mucilage from medicinal plants offers a relaxing and soothing effect to endodermal lining gut has antacid properties, which can protect mucosal acidity. This is first report aimed evaluate physicochemical characteristics, acid-neutralizing, cytotoxicity properties traditionally used aqueous mucilage Aspa...

In dyspepsia, formulations known as antacids are regularly used to alleviate symptoms quickly possible. Gastric contents acidic; therefore, usually weak bases with the potential neutralize excess acid and raise gastric pH accordingly. Acid-neutralizing capacity is what determines effectiveness of an antacid. Some antacid tablets formulation from different manufacturers were tested for their aci...
