Aspergillus brasiliensis (ATCC® 16404MINIPACK™)
Strain Designation: WLRI 034(120) [CBS 733.88, DSM 1387, DSM 1988, IFO 9455, IMI 149007, NCPF 2275] Deposited Name: Aspergillus niger van Tieghem Product Description: ATCC® 16404MINIPACK™ consists of 6 readytouse vials of ATCC® 16404™ frozen in 200 µL of glycerol stock, eliminating the need to rehydrate and culture the strain prior to use. Each vial is provided with a 2D barcode for easy storage and tracking, as well as peeloff labels for fast and reliable recordkeeping. The information recommended in this section is to assist users in obtaining living culture(s) for their studies. The recommendation does not imply that the conditions or procedures provided below are optimum. Experienced researchers may initiate the growth of a culture in their own way. ATCC® Medium 336: Potato dextrose agar (PDA) ATCC® Medium 325: Malt extract agar (Blakeslee's formula) ATCC® Medium 28: Emmons' modification of Sabouraud's agar Growth Conditions Temperature: 20°C to 25°C Atmosphere: Typical aerobic Recommended Procedure Frozen minicryovials packed in dry ice should either be thawed immediately for use or stored at or below 70°C until the expiration date printed on the label. Shortterm storage at 20°C is acceptable for up to 6 months. 1. To thaw a frozen minicryovial, place the vial upright in a 25°C to 30°C water bath, until just thawed (approximately 23 minutes). Immerse the minicryovial just sufficient to cover the frozen material. Do not agitate the minicryovial. 2. Immediately after thawing, wipe down the minicryovial with 70% ethanol and aseptically transfer at least 50 µL (or 23 agar cubes) of the content onto a plate or broth with the recommended medium. 3. Discard the empty vial. Do not refreeze any unused portion as it will result in a loss of viability. 4. Incubate the inoculum/strain at the temperature and conditions recommended. Inspect for growth of the inoculum/strain regularly. Viability is typically noticeable after 23 days of incubation. However, the time necessary for significant growth will vary from strain to strain. Colony and Cell Morphology: Colonies initially white or yellowish, mycelium growing rapidly producing a dense layer of erect smoothstiped, conidiophores terminated by globose vesicles bearing phialides (uniseriate) or metulae with phialides (biseriate) which produce dry chains of conidia. Reverse pale to grayish or greenish yellow. Vesicles radiate, initially pale, becoming dark brown to black. Conidia spherical, midtodark brown, highly roughened with ridges and blunt or pointed protuberances, (3)45(6) µm in diameter. Sporulation may be inhibited when grown in vessels with reduced gas exchange. Colonies may exhibit sectoring with areas of varying levels of sporulation. Use of freshly produced spores as inoculum should reduce sectoring. This strain was identified as belonging to the new species Aspergillus brasiliensis (see Varga et al. 2007 and Houseknecht et al., 2008.)
