Chromogenic Listeria Agar Base (ISO) 500g

Brand:

Thermo ScientificTM OxoidTM

This product has been discontinued, please refer to CM1212B

Isolate, enumerate and differentiate Listeria species and Listeria monocytogenes from food samples with Thermo Scientific™ Oxoid™ Chromogenic Listeria Agar (ISO) (Dehydrated). Chromogenic Listeria Agar (ISO) contains lithium chloride, polymyxin B, nalidixic acid, and amphotericin which act to inhibit non-target organisms. A combination of chromogenic and phospholipase enzyme reactions easily differentiate Listeria monocytogenes (blue colonies surrounded by an opaque halo) from other Listeria spp. (blue colonies without an opaque halo).

Precautions
Colonies of Clostridium difficile from faecal cultures are smaller when egg yolk is used in place of horse blood.

The Oxoid formula does not contain the neutral red indicator proposed by George et al. because it is designed for use with horse blood. On this medium the typical colour of the colony of Clostridium difficile will not appear however there will be a fluorescent reaction.

Typical Gram stain morphology of Clostridium difficile may not be evident in colonies picked from this medium because of the antibiotics present. Subculture to blood agar to obtain characteristic morphology.

General Description
COi8DFIC or O6T-4F is a highly efficient, n-type, low-bandgap nonfullerene acceptor with strong NIR absorption.
In a recent study, COi8DFIC or O6T-4F was selected in a Tandem cell by computer assited design and gave a record PCE of 17.3∃% for fabricated organic solar cells.
COi8DFIC or O6T-4F is frequently selected to blend with a narrow-bandgap donor material and another narrow bandgap acceptor material to fabricate ternary organic solar cells. The PTB7-Th:COi8DFIC:PC71BM ternary cells offered a PCE of 14.08%. By further adopting a post-annealing process, an outstanding PCE of 14.62% can be achieved. Furthermore, the device utilizing COi8DFIC exhibited a good thermal stability with PCEs over 13.5% in a wide temperature range (70–160 °C).

Application
COi8DFIC is primarily utilized as a non-fullerene acceptor in OPV devices. It exhibits a broad absorption spectrum, enabling it to absorb light across a wide range of wavelengths, including the visible and near-infrared regions. This property allows for efficient utilization of a broader range of solar radiation, enhancing the light-harvesting capability of the OPV device. COi8DFIC can be employed as the electron transport material in OFET devices.
