Effect of Phosphate solubalizing microorganisms [PSM] mixed with black and
red soil is studied on growth of Triticum aestivum. Density of bacteria was about
thrice in black soil while fungi density was reduced to about fifty percent when
compared with biofertilizer as control. Germination percentage and shoot length
was almost unaffected while increased chlorophyll content was noted in seedlings
grown in black and red soil mixed with biofertilizer.

The samples of sea urchin shell walls were collected from the beach and later
on the fungi residing on its calcareous shell was isolated. On culturing in PDA,
these fungi were identified as Bipolaris spp. and Aspergillus spp. The best growth
conditions for Aspergillus spp were studied, by varying the pH and by calcium,
concentration of Potato Dextrose Broth, and thereby measuring the dry weight of
the fungal biomass. The optimum pH for its growth was pH seven with a biomass
dry weight of 2. 58gm. The fungal species showed maximum growth (biomass dry
weight of 0. 89gm) for a Calcium concentration of 75 ppm in the media with an
