The serial dilution culture-most probable number assay to estimate phytoplankton concentrations in ballast water: comments and improvements

Frontiers in Marine Science
In ecology, the enumeration of living aquatic unicellular protists is a century-old complicated task. The organisms are small, perhaps motile, and if they are non-motile their vitality is hard to gauge.

Coexistence of immunophenotypically normal and aberrant mast cells in patients with clonal mast cell diseases associates with more indolent subtypes and less severe disease characteristics

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Aberrant antigen expression on mast cells (MCs) is one of the most accurate diagnostic markers for clonal MC diseases (CMCD). Although the coexistence of normal and pathologic MCs is frequently seen, the disease characteristics associated with it have been minimally investigated.

MPN (Most Probable Number) assay for infectivity of algal viruses v3

, 2016
Purpose: To quantify infectious viruses and evaluate the infectivity of a viral sample. Summary: 50 µL of serially-diluted (10-3 to 10-10) virus sample is added to 150 µL of exponentially growing host cells in triplicate 96-well microplates and incubated at normal growth conditions for ~2 weeks.

Estimation of the Number of Polyhydroxyalkanoate (PHA)-Degraders in Soil and Isolation of Degraders Based on the Method of Most Probable Number (MPN) Using PHA-Film

Bioscience, Biotechnology, and Biochemistry, 2001
A new method to estimate the number of polyhydroxyalkanoates (PHA)-degraders in soil and to isolate degraders, called the film-MPN method, is proposed. The incubation time was measured by the first order reaction (FOR) model. This method was used to estimate numbers of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)[P(3HB-co-3HV)]- and poly(3 ...

Antimicrobial bilayer starch film containing zein electrospun fibers encapsulating thyme essential oil for cherry tomato packaging

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background This study evaluated the antimicrobial activity of thyme essential oil (TEO) encapsulated in electrospun zein fibers for use in bilayer films as active packaging for cherry tomatoes. The antimicrobial activity of TEO and bilayer films with 20%, 40%, and 60% TEO was assessed with agar diffusion and microatmosphere assays.

Environmental monitoring of waterborne Campylobacter: evaluation of the Australian Standard and a hybrid extraction-free MPN-PCR method.

Frontiers in Microbiology, 2015
Campylobacter is the leading agent of diarrheal disease worldwide. This study evaluates a novel culture-PCR hybrid (MPN-PCR) assay for the rapid enumeration of Campylobacter spp. from estuarine and wastewater systems.

Turbidity measurements in 96-wells microplates to determine the densities of copiotrophic and oligotrophic bacteria with the Most-Probable-Number-method during POLARSTERN cruise ANT-XI/2

, 1996
A new microtiter-plate dilution method was applied during the expedition ANTARKTIS-XI/2 with RV Polarstern to determine the distribution of copiotrophic and oligotrophic bacteria in the water columns at polar fronts.

Metal Polyphenol Network Enables Photo‐ATRP Under Blue Light

Macromolecular Rapid Communications, EarlyView.
A new ligand for light‐mediated ATRP derived from a model polyphenol was modified via a Mannich reaction to form a complex with an iron‐based photocatalyst. Experiments confirmed the formation of chain‐extendable macroinitiators, as well as fractions of polymers incapable of chain extension.
