  In this work we investigate the following chemo-attraction with consumption
model in bounded domains of \, $\mathbb{R}^N$ ($N=1,2,3$):
  $$ \partial_t u - \Delta u = - \nabla \cdot (u \nabla v), \quad
  \partial_t v - \Delta v = - u^s v
  $$ where $s\ge 1$, endowed with isolated boundary conditions and initial
conditions for $(u,v)$. The main novelty in the model is the nonlinear
potential consumption term $u^sv$.
  Through the convergence of solutions of an adequate truncated model, two main
results are established; existence of uniform in time weak solutions in $3D$
domains, and uniqueness and regularity in $2D$ (or $1D$) domains. Both results
are proved imposing minimal regularity assumptions on the boundary of the
domain.
