VAIRO, MARINA L. R. (University of Sao Paulo, Sao Paulo, Brazil) AND WALTER BORZANI. Precise adsorption method for measuring the percentage of dead bacterial cells. Appl. Microbiol. 10: 500-503. 1962.-It was observed that Freundlich's law is obeyed when methylene blue is adsorbed from different aqueous solutions by mixtures of dead and live bacterial cells. A simple and precise colorimetric met...

Quantitative adsorption of methylene blue by dead yeast cells.

Quantitative studies of dye adsorption by bacteria have been made (Kennedy and Barbaro, 1953; Barbaro and Kennedy, 1954; Kennedy and Woodhour, 1956; Barbaro et al., 1956) in order to measure the degree of gram-positiveness, and to study the influence of several factors on the quantity of dye retained by the microorganisms. No attention has been given, however, to the applicability of the physic...

Assessment of Umbilical Cord Nucleated Red Blood Cell Count in Discharged and Dead Very Low Birth Weight Infants

Background: Predictive value of the umbilical nucleated red blood cells (NRBCs) at birth for neonatal outcomes has been assessed. Hence, the present study was conducted to compare NRBC between discharged and dead neonates.Methods: This cross-sectional study was performed on preterm newborns with a birth weight of < 1,500 g admitted to the Neonatal Intensive Care Unit of Ghaem Hospital, Ma...

Comparative Study on the Ni2+ Biosorption Capacity and Properties of Living and Dead Pseudomonas putida Cells

Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...
