The count of
mesophiles present in sierra muscle was developed according to the methodology described in the Official Mexican Norm Regulation NOM-092-SSA1-1994 [8].
Linked to that is the appearance of very diverse tetrapod tracks and the re-occurrence of
mesophile flora and invertebrate burrows (Scoyenia).
In that case anisotropic growth (elongation) of the veins is combined with angle-dependent growth of the
mesophile.
The new microorganisms included not only
mesophiles (needing a moderate amount of heat to grow), but also thermophiles (needing higher temperatures to grow).
Plate
mesophile and psychrotrophile count; 11g of the sample were added to 99 ml of peptonated water (0.1% w/v) and placed in petri dishes with PlateCount Agar and incubated at 35 [+ or -] 2[degrees]C for 48 hours.
The high water salinities limit the plant growing to the
mesophile systems: the moderate water consumption limits the salt "storage" in the plant organism.
Whereas plates for
mesophile counts were stored at 35[degrees]C for 48 hours, plates for psychrotrophic counts were stored at 3.5[degrees]C for 10 days.
The samples of third stage were analyzed in terms of microbiological (total
mesophile aerobe bacteria (TMAB), psycrophile bacteria (PB), lactic acid bacteria (LAB), Enterobacteria (EB), yeast and mould (YM)), chemical (pH total volatile basic nitrogen value (TVB-N) and thiobarbituric acid number (TBA)), organoleptic (view, texture, colour, odor, total assesment) and colour criteria (L , a and b values).
Total bacterial counts were numerically lower for electrical stimulation tissue, but did not significantly change the
mesophile, thermophile, and psychrotrophile growth in precooked roast beef at d 7.
Nowadays, commercial PE is obtained from
mesophile rhodophyta Porphyridium (phycoerythrin) and available from various companies including AnaSpec Inc., Sigma-Aldrich Corporation and Invitrogen Corporation.
Total aerobic and
mesophile flora of the flour were not different from the recommended values (p=0.199).
Microbial analysis showed no significant difference in aerobic
mesophile and absence of total Coliforms and Escherichia coli.
