Bioremediation of polycyclic aromatic hydrocarbons (PAHs) is extremely challenging when they coexist with heavy metals. This constrain has led to adsorption-based techniques that help immobilize the metals and reduce toxicity. However, the adsorbents can also non-selectively bind the organic compounds, which reduces their bioavailability. In this s...

Hi there,
This Bacteria is EPS-producing and already clumpy. My interest is to get bacterial cells but not the EPS/biofilm made by these cells. Apart from ion resin protocol, is there any useful method I can exercise? Thanks for your suggestion!
Question
Hi, 
This is a bi-exponential or double-first-order in parallel
(DFOP) model: (C = C0(ge−k1t + [1 − g]e−k2t)) 
where C is the concentration at time t, C0 is the initial
concentration at time 0, k1 values are degradation rate constants at compartment 1 (rapid phase) and k2 is for compartment 2 (slow phase), g is
the fraction of C0 applied to compartment 1.
Often the value should come k1>k2, which means rate is higher in rapid phase.I only saw one article who obtained k2>k1. I am also getting k2>k1, actually means show degradation has higher rate than rapid degradation. On the other hand, I am getting g value 60% which means ~60% of initial concentration is being degraded at compartment 1 i.e. in rapid phase. Is this a contradictory? Could anyone please share your experience and expertise here? it was a biodegradation of PAH in soil and this model is fitting with very good-fitting than single first-order, except this confusing explanation. Thank you
