count was repeated twice (n = 2), and the remainder of the analytical determinations, four times (n = 4).

Nucleotide and protein sequences of [beta]-galactosidase of thermophiles, mesophiles
, and psychrophiles were retrieved from NCBI (http://www.ncbi.nlm .nih.gov/) and UniProt proteomic server (http://www.uniprot.org/), respectively.
Raw seaweeds exhibited a complete absence of aerobic mesophiles
, halophiles, yeasts and molds.
The microbiological quality of hamburger of chicken (HP) elaborated in artisan and industrial form was evaluated by means of the determination of mesophiles
aerobics (AM), total coliforms (CT), fecal coliforms (CF) Escherichia coli (EC) and Salmonella's presence, following methodologies of the Venezuelan Commission of Industrial Norms (COVENIN).
Within that range there are organisms that grow best when the temperature is < 10[degrees]C (< 50[degrees]F; cryophiles or psychrophiles), 10 to 40[degrees]C (50 to 104[degrees]F; mesophiles
), and > 40[degrees]C (> 104[degrees]F; thermophiles).

et des groupements hygrophiles du Monte Pollino (Calabre) -- Phyton 14: 271-280.
If, however, the objective is to determine the total surface bioburden, consider incubating the samples at 22[degrees]C for 24, 48, or 72 hours, or all three, to recover psychrophilic organisms, and follow this step with incubation at 36[degrees]C to recover the mesophiles
. We found it wise to check the sequentially incubated samples frequently (at least every six to 12 hours) to recognize changes in growth before the formation of confluent colonies by molds and other rapid-growth organisms.
In contrast, most fungi are considered mesophiles
, growing optimally between 15 [degrees] and 30 [degrees] C (59 [degrees]-86 [degrees] F) (8).
