  We find 132 face-on and low inclination galaxies with central star formation
driven biconical gas outflows (FSFB) in the SDSS MaNGA (Mapping Nearby Galaxies
at APO) survey. The FSFB galaxies show either double peaked or broadened
emission line profiles at their centres. The peak and maximum outflow
velocities are 58 and 212 km/s, respectively. The gas velocity dispersion
reveals a mild dependence on the central star formation surface density
compatible with models of gas dispersion powered by the Jeans instability in
gas clumps or by gas turbulence dissipation. We estimate the gas outflow rate
and conclude that the central gas depletion time does not depend on galactic
mass. In turn, the ratio of the gas outflow rate to the gas consumption rate by
the star formation is low in massive galaxies and high in low-mass objects,
while the star formation is a more rapid process of the gas consumption. We
compare properties of the FSFB galaxies with a control sample of 375 comparison
galaxies and find that the FSFB objects have high central concentration of star
formation, and also younger central stellar population with respect to their
periphery. We analysed the environment of the galaxies and identified nearby
satellites and elements of low surface brightness structure. We see that many
tidal-enhanced features that can be assigned to early and intermediate stages
of galactic interaction are much more frequent in the FSFB galaxies with
respect to the comparison sample. We conclude that the gas should be
replenished via the accretion from small satellites.
