In addition, mesophile
growth was evaluated at 0, 5,10, and 15 days.
microbiological analyses were performed according to APHA (2001) for counts of molds and yeasts and total mesophiles
and the results expressed in CFU / g, Salmonella sp./ in 25 g and total coliforms at 35[degrees]c and fecal coliforms at 45.5[degrees]c, with results expressed in [MPN.g.sup.1].
Outside the Deinococci species, the best studied Csps come from the mesophile
Escherichia coli, although putative Csps have been identified from psychrophiles, mesophiles
, and thermophiles .
Al-Holy, Lin, and Rasco (2005) investigated the effect of nisin in combination with heat treatments or antimicrobials (such as lactic acid, chlorous acid and sodium hypochlorite) on the inhibition of Listeria monocytogenes and total mesophiles
in caviar and concluded that there was no synergistic effect due to the combination of nisin with lactic acid.
The researches on low temperature anaerobic digestion for methane production are mainly concentrated on low temperature acclimatized mesophiles
which are psychrotrophs not exact psychrophiles (Kashyap et al.
 defined this method as any procedure in which indigenous microorganisms (thermophiles and mesophiles
) transform organic compounds by means of aerobic processes.
While esterases from halophilic microbes are in most cases active only at high salt concentrations, the salt tolerant esterases from mesophiles
can act both in the absence of NaCl and in a range of NaCl concentrations.
This enzyme is present in psychrophiles [4, 7], mesophiles
, thermophiles [9, 10], and hyperthermophiles [11, 12].
Lab M's Iron Sulphite Agar is a versatile medium that can be used with the standard industry methodologies - Deep-Shake Culture or Attenborough and Scarr membrane filter methods and can be incubated at temperatures suitable for the detection of thermophiles or mesophiles
. Its reduced sodium sulphite content supports improved detection of some strains of Cl.sporogenes.
(n = 3) Medium Range counts ([log.sub.10] cfu/g Without With root root Total aerobic mesophiles
8.41-8.88 6.43-6.92 Lactobacillus & Leuconostocs 8.46-8.97 7.41-7.91 Lactobacillus & Streptococcus 7.40-7.92 6.40-6.88 Lactobacillus spp.
We maintained cultures at 37[degrees]C to allow for the growth of most mesophiles
, which flourish at a range of 20-45[degrees]C, and because bacteria that are obligate commensals of humans would grow best at this temperature.
Role and contribution of pure and mixed cultures of mesophiles
in bioleaching of a pyritic chalcopyrite concentrate.
