Nitrous oxide production in soil isolates of nitrate-ammonifying bacteria [PDF]
, 2012 Here we provide the first demonstration of the potential for N2O production by soil-isolated nitrate-ammonifying bacteria under different C and N availabilities, building on characterizations informed from model strains.

Nonautonomous Chemostats with Variable Delays [PDF]
SIAM Journal on Mathematical Analysis, 2015 The appearance of delay terms in a chemostat model can be fully justified since the future behavior of a dynamical system does not in general depend only on the present but also on its history. Sometimes only a short piece of history provides the relevant influence (bounded or finite delay), while in other cases it is the whole history that has to be ...

Coexistence of an unstirred chemostat model with B-D functional response by fixed point index theory
Journal of Inequalities and Applications, 2016 This paper deals with an unstirred chemostat model with the Beddington-DeAngelis functional response. First, some prior estimates for positive solutions are proved by the maximum principle and the method of upper and lower solutions.

Severe zinc depletion of escherichia coli: roles for high affinity zinc binding by ZinT, zinc transport and zinc-independent proteins [PDF]
, 2009 Zinc ions play indispensable roles in biological chemistry. However, bacteria have an impressive ability to acquire Zn2+ from the environment, making it exceptionally difficult to achieve Zn2+ deficiency, and so a comprehensive understanding of the ...

Location of catalase in crystalline peroxisomes of methanol-grown Hansenula polymorpha [PDF]
, 1992 We have studied the intraperoxisomal location of catalase in peroxisomes of methanol-grown Hansenula polymorpha by (immuno)cytochemical means. In completely crystalline peroxisomes, in which the crystalline matrix is composed of octameric alcohol oxidase

Controlling evolutionary dynamics to optimize microbial bioremediation
Evolutionary Applications, 2020 Some microbes have a fascinating ability to degrade compounds that are toxic for humans in a process called bioremediation. Although these traits help microbes survive the toxins, carrying them can be costly if the benefit of detoxification is shared by ...

Dynamics of Nonautonomous Chemostat Models [PDF]
, 2015 Chemostat models have a long history in the biological sciences as well as in biomathematics. Hitherto most investigations have focused on autonomous systems, that is, with constant parameters, inputs and outputs. In many realistic situations these quantities can vary in time, either deterministically (e.g., periodically) or randomly. They are then non-
