Mycotoxin production on rice, pulses and oilseeds.

Mycotoxin-producing fungi were isolated from contaminated grains of rice, pulses and oilseeds sold in the local markets of Calcutta for human consumption. It was found that aflatoxin B1 was produced by Aspergillus flavus and Aspergillus parasiticus, aflatoxin G1 by A. flavus, ochratoxin by Aspergillus ochraceous, sterigmatocystin by Aspergillus japonicus and citrinin by Penicillium citrinum. Aflatoxin B1 (333-10,416 micrograms/kg) was produced by Aspergillus spp. in rice, pulses and oilseeds.

Preliminary studies on excretory components of a virulent strain (F-2) of Pseudomonas solanacearum.

The excretory material (EM) was isolated from the culture medium of a virulent strain (F-2) of Pseudomonas solanacearum. Electrophoretic studies depicted the heterogeneous nature of EM and the presence of released lipopolysaccharide in it. Both the exopolysaccharide and the released LPS contained D-galactose as the major sugar constituent together with D-glucose, N-acetyl-D-galactosamine and N-acetyl-D-glucosamine. In addition, L-rhamnose was present as a constituent sugar of the released LPS.

Effect of different nitrogen sources on the yield of oxalic acid by Sclerotium rolfsii.

Of the different sources of nitrogen used for the yield of oxalic acid by parent and X-ray mutated strains of Sclerotium rolfsii, organic nitrogen sources gave better results than inorganic nitrogen sources. Cysteine is the best nitrogen source for the parent and one mutant strain while phenylalanine is for the second one.

Glucose and phosphorus utilization by two dermatophytes.

Trichophyton mentagrophytes and Aspergillus fumigatus dissimilated glucose through EMP pathway. Oxygen and inorganic phosphorus were found to control the rate and extent of glucose metabolism.
