Does species  produce  a capsule under  all  conditions of   cultivation.

NO   species   does not  produce  a  capsule  under all condition of  cultivation.  some  do it  differently.

Explanation

For  instance the bacteria zooglea secret fibres  of  cellulose that  enmest  the bacteria into floc that floats on  the surface of liquid which keeps the bacteria exposed  to air.
