Optimization of Pre-Enrichment and Screening Methods for the Detection of <em>Salmonella enterica</em> in Meat Analog Products
… and are time-consuming and costly, requiring pre-enrichment using lactose broth (LB) with a surfactant (e.g., Triton X-100). Therefore, this study aimed to optimize pre-enrichment and screening methods for the detection of Salmonella in meat analogs by comparing the current FDA reference …

Single-Laboratory Validation for the Detection of <em>Salmonella enterica</em> in Meat Analog Products
… (BAM) chapter on Salmonella detection calls for pre-enrichment of meat analogs using lactose broth (LB) with added surfactants, Tergitol Anionic 7 or Triton X-100. However, it remains to be determined whether surfactants are necessary for pre-enrichment of meat analogs. Following pre-enrichment, …

Assessing the Efficacy of Bacteriological Analytical Manual (BAM) Enrichment Broths for Detection of <em>Salmonella</em> spp. in Meat Analogs
… used Bacteriological Analytical Manual (BAM) pre-enrichment broth (lactose broth) with two additional broths (universal pre-enrichment broth and buffered peptone water) for the detection of <em>Salmonella</em> in five plant-based burger products. Each burger product was spiked with a …

Characterizing the mechanism and rate of calcium phosphate precipitation in aerobic granular sludge
… removal while enhancing recovery through the precipitation of calcium phosphate minerals within the granule1–3. A rigorous understanding of precipitation mechanism and rate has been limited by simultaneous biological uptake and release of phosphate and cations. As a result, more work is needed …

On the Ionization and Chemical Evolution of the Intergalactic Medium
… of this work, we address topics on the metal enrichment of the IGM. An overview of the current research in the cosmic metal evolution is provided in Chapter (5). In Chapter (6), we investigate the pre-enrichment of the IGM by parametrizing the metal abundance as dependent on the local baryon …

Capture filtration for concentration and detection of selected microorganisms in milk
… of an adsorption filter in retaining bacteria present in milk was examined. Skim milk and whole milk (100ml) were separately filtered through a 47mm adsorption filter. No significant change in total solids, total fat, and solids-not-fat percentages of skim and whole milk permeates was observed …

Encoded synthesis and evolution of clinically approved 2'-modified ribonucleic acids
… 2'-modified nucleic acids is limited in length, prevents parallel exploration of different sequences and modifications, and precludes evolution. This study aims to develop an encoded enzymatic synthesis approach using polymerase engineering to enable the efficient synthesis of 2'OMe-RNA and …

Development of novel methods for the detection of Vibrio parahaemolyticus in seafood
… that the ELISA reaction was inhibited by the presence of oyster homogenate. Therefore, a3h pre-enrichment step was necessary before testing for the presence of bacterial cells. The phage antibody clones which showed strong binding in pure culture still retained their binding capacity, when …
