Biodegradation of Atrazine Herbicide: A Mini-review

New Aspects on Atrazine Biodegradation

The world practice of using agrochemicals for long periods, in an indiscriminated and abusive way, has been a concern of the authorities involved in public health and sustainability of the natural resources, as a consequence of environmental contamination. Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively...

Atrazine and Non-Atrazine Herbicide Comparisons in Conventional Till Corn

Biodegradation of an s-triazine herbicide, simazine

Two types of simazine-degrading microorganisms were isolated from soil samples where the herbicide had been spread with the enrichment culture using simazine as the sole carbon and nitrogen source. A fungal strain, DS6F, identified as Penicillium steckii, is the first simazine-degrading fungus ever reported. Ž Simazine was gradually degraded by P. steckii DS6F in the mineral medium containing s...

Diffusion Limitation for Atrazine Biodegradation in Soil

Effects of sub-millimeter scale heterogeneity in chemical and microbial distributions on atrazine degradation were examined using Pseudomonas sp. strain ADP introduced into soil at a population mimicking atrazine-adapted soils (~2000 cells/g), and employing a range of soil water pressures (−100, −300, −500 kPa). Heterogeneous cell distribution was employed in all treatments whereas uniformity o...

Fasting and apoptosis: a mini review

Fasting, that is usually described as abstinence from all food and drink for a period of time, has been experienced for ages. Health, protest, religious expressions of devotion and purification are the most important reasons for fasting. Many changes occur in the body during fasting including metabolic, mineral, hormonal, immunological and psychological. Its use as one of the oldest therapies a...
