Polygalacturonate lyase activity in Bacteroides from the human colon
… have been found to degrade polygalacturonic acid and/or pectin. Four of these strains were examined for presence of polygalacturonate lyase (PGAL). The Bacteroides strains studied synthesized inducible, cell-associated PGALs when the bacteria were grown on media containing polygalacturonic …

Protein partition and digesta flow in lactating Holsteins fed 2:1 and 1:2 soybean meal:fish meal
… 15. 9 and 16.0 percent protein. Ruminal cobalt ethylenediaminetetraacetic acid (CoEDTA) infusions marked liquid phase (LP) digesta and Yb-soaked hay was used as a solid phase (SP) marker. Duodenal digesta was separated into SP and LP at 3000xg. Least squares means of LP flows did not differ for …

Development and evaluation of novel antimicrobial solutions against biofilms and planktonic microbial growth
… Each solution is compiled of three reagents; Ethylenediaminetetraacetic acid (EDTA), hydrogen peroxide, and ethanol, were used against planktonic (free-floating) microorganisms and biofilms (aggregated microorganisms). The Planktonic assay implemented use of a Millipore Filtration system. The …

pH Stability of Calcium Hydroxide Preparations in a Simulated Acidic Environment
… However, its efficacy is challenged by the acidic pH of purulent exudates in infected root canals. This study aimed to evaluate the pH stability of three calcium hydroxide preparations—BC Temp (bioceramic-based), UltraCal XSTM, and mixed Ca(OH)₂ powder with saline—in simulated acidic and …
