Malt Extract Contact Agar- Room Temp [Pack of 20]

Description

Ten contact plates each with a diameter of 55 mm are single-bagged in transparent, hydrogen peroxide impermeable sleeves (non-irradiated). The sleeves consist of polypropylene with a barrier of PE-EVOH-PE
The Malt Extract Agar is available as settle and contact plates with the same composition:
• Malt Extract Contact Agar – RT, article number 146191 in 55 mm contact plates
• Malt Extract Agar, article number 146151 in 90 mm settle plates

Mode of Action
The low pH of the medium promotes the growth of most yeasts and fungi, while bacterial growth
is more or less strongly inhibited. Malt extract has a high content of carbohydrates (90-92 %), but
also of nitrogen compounds and vitamins, e.g. riboflavin, pyridoxin, and thiamine. The soymeal
peptone content, also rich in carbohydrates, additionally supplies the necessary protein compounds
such as peptides and amino acids. This composition facilitates the good growth of yeasts, fungi, and
dermatophytes.

Typical Composition
Malt Extract   30 g/l
Soytone        3 g/l
Agar             20 g/l

The appearance of the medium is clear and yellowish. The pH value is in the range of 5.4 to 5.8.
The medium can be adjusted and/or supplemented according to the performance criteria required.

Application and Interpretation
Each plate is provided with a label including a data matrix code for paperless plate identification.
The code consists of a two-dimensional 20-digit serial number, which harbors the following
information:
digits 1-3: here code 871 (corresponds to article 146191); digits 4-9: lot number; digits 10-
14: batch specific individual number; digits 15-20: expiration date (YY/MM/DD).
Please check each agar plate before using it on sterility and pay attention to aseptic handling in
order to avoid false positive results.
Lit. No. TN5780EN00
The culture medium is incubated aerobically for at least 2 days, generally however for 7 – 14
days, at 25 ± 1 °C.
The microscopic assessment (1:200- to 1:1000-fold magnification) is an important indication
for the characterization of the cultivated yeasts and fungi. The colonization forms (conidia, helical
formations, spiked formations) are frequently of essential importance for the characterization of
the fungi.

Storage and Shelf Life
The product can be used for sampling until the expiry date if stored upright, protected from light
and properly sealed at +2 °C to +25 °C.
The testing procedures as described on the CoA can be started up to the expiry date printed on the
label.

Disposal
Please mind the respective regulations for the disposal of used culture medium (e.g. autoclave for 20
min at 121 °C, disinfect, incinerate etc.).
