Agricultural Pest Management: The Role of Microorganisms in Biopesticides and Soil Bioremediation.

Pesticide use in crops is a severe problem in some countries. Each country has its legislation for use, but they differ in the degree of tolerance for these broadly toxic products. Several synthetic pesticides can cause air, soil, and water pollution, contaminating the human food chain and other living beings.

Evaluation of carbon:nitrogen ratio in semi-defined culture medium to tacrolimus biosynthesis by and the effect on bacterial growth.

Tacrolimus is an immunosuppressant produced by several species, widely used in transplantolgy and dermatology. In this report, attempts have been made to enhance tacrolimus productivity by altering the primary carbon source on culture media. In order to better understand the effects of glucose and maltose on tacrolimus biosynthesis, different carbon contents of these sugars were evaluated in the culture media, thus altering the carbon:nitrogen ratio.
