2011) who found that
lag phase was basically negligible ([lambda] =0) in all of the cases, which from a biological perspective is invalid, since it would break the assumption that microbial consortia were formed by spontaneous generation and thereby these models would not be suitable to predict methane production.
Karpouzas and Walker (2000) suggested that these longer
lag phases might because of the requirement of larger microbial number and acclimation period to begin enhanced biodegradation.
Thus, a
lag phase of 10 days was required for methanogens to acclimatize the feedlot manure.
Future research to work out the regulatory mechanisms behind these processes and the switch from
lag phase to exponential growth will tell us more about how Salmonella can flourish in different environments, and could point to new ways of controlling its transmission in the food chain.
This study reveals that, there is no observation of immediate cell growth on microcarrier but the
lag phase was about 24 and cells reached confluence six days after inoculation.
Thus, between day 0 and day 3, the cells were in their
lag phase whereas after day 3, the cells entered the exponential phase.
At this phenol concentration, in the absence of GAC, the suspension cells experienced a short
lag phase of about 5 h before phenol was gradually degraded, concomitant with cell growth.
where KW is kernel weight, TT is thermal time after anthesis, a is the y-intercept (mg), b is the kernel growth rate during the
lag phase (rag [degrees][Cd.
5 [micro]M-10 [micro]M) in the presence of Cu(II) a concentration-dependent increase in the
lag phase was observed.
The PPC on fillets stored at 4 [degrees]C did not show any
lag phase and grew rapidly; while APC of fillets stored at 0 [degrees]C had two days of
lag phase.
We computed the
lag phase of oxidation using the time course curve (21) from the three indices of oxidation.
The culture incubated at -2[degrees]C demonstrated a relatively longer
lag phase when compared to the culture grown at 22[degrees]C, which is probably due to the slower metabolic rates at colder temperatures.
