Curd : Less important for society - as it depends on individual use and has only nutritions value.
Citric acid: Industrial use, not for dissipation in community.
Penicillin : Medicinal use of microbes, good for health of society, commercially more usable.
Biogas: Most important for community welfare as
(i) it reduces excreta, waste from community.
(ii) it produces inflammable gases, can be used as energy source.
(iii) it is a renewable source.
(iv) it has multidimensional utility.
(v) it is easily maintained and dissipated for community purpose.
So, Penicillin $>$ Biogas $>$ Curd $>$ Citric acid.
