Effects of herbicides on soil enzyme L-asparaginase activity

L-Asparaginase-producing Rouxiella Species Isolation, Antileukemia Activity Evaluation, and Enzyme Production Optimization

Background: L-Asparaginase (L-Asp) is used as an efficient anti-cancer drug, especially for acute lymphoblastic leukemia (ALL). Currently, two bacterial asparaginase isoenzymes are used for cancer treatment. Therefore, this research focused on isolating native bacteria with the ability to produce L-Asp.  Materials and methods: L-Asp producing bacteria were isolated from soil samples on 9K medi...

Imazethapyr Effects on Soil Enzyme Activity and Nutrient Uptake by Weeds and Greengram (Vigna radiata L.)

Imazethapyr is a broad spectrum herbicide used as early post-emergence in pulses, oilseeds and leguminous crops. Imazethapyr is an imidazole compound used as a selective herbicide. The compound controls weeds by reducing the levels of three branched-chain aliphatic amino acids, isoleucine, leucine and valine, through the inhibition of aceto-lactate synthase (ALS), an enzyme common to the biosyn...

Toxic effects of four sulphonylureas herbicides on soil microbial biomass.

The effect of four triazinyl-sulfonylurea herbicides (cinosulfuron, prosulfuron, thifensulfuron methyl, triasulfuron) on soil microbial biomass, soil respiration, metabolic activity, metabolic quotient, and some enzymatic activities (acid and alkaline phosphatase, β-glucosidase, arylsulphatase, and fluorescein diacetate hydrolysis) were monitored under controlled conditions over 30 days. The he...

Comparative Study of L-asparaginase Activity in Different Bacterial Species

Inhibitory Effects of Six Allium Species on ?-Amylase Enzyme Activity

Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. The management of the blood glucose level is a critical strategy in the control of diabetes complications. Inhibitors of carbohydrate hydrolyzing enzymes have been useful as oral hypoglycemic drugs for the control of hyperglycemia especially in patients with type II disables mellitus. The goal of the present study...
