DETERMINATION OF THE EXTRACELLULAR ENZYME ACTIVITY IN SOIL

A field experiment was conducted during kharif, 2017 at the Main Agricultural Research Station, agriculture college farm, Raichur to study the “Activity of soil enzyme and microorganisms in rhizosphere soil of maize (Zea mays L.) as influenced by different weed management practices”. The experiment[r]

In this respect, soil FDA is an important indicator of soil microbial activity and biological health of soil. The aim of this research was to assess the effects of crop residue retention and P fertilization on FDA activity in soil.

Endoglucanase is one of the most important industrial enzymes. In the present study, three different fungi Aspergillus sp., Trichoderma sp. and Penicillium sp. were isolation for endoglucanase production from soil samples on PDA plate. All three fungus processed by submerged fermentation and solid s[r]

Wheat (Triticum aestivum L.) production is often affected due to micronutrient status in soil. Micronutrient deficiency in soil including Boron is very much prominent in India, due to prevalent environmental and soil conditions (viz., wide variation in soil pH, organic matter, salt stress, supply of[r]

Presently thermal treatment is most commonly applied for inactivating enzymes in coconut water. Thermal treatment required less maintenance and low energy consumption. By considering the facts, the present experiment was aimed to study the effect of thermal treatment on bioactive components and enzy[r]

TEST 1: The term weathering refers to all the ways in which rock can be broken down. It takes place because minerals formed in a particular way (say at high temperatures, in the case of igneous rocks) are often usable when exposed to various conditions. Weathering involves the interaction of the lit[r]

Soil samples collected from two termite mound soils in Anna University campus, Chennai, Tamil Nadu were characterized for the various parameters such as pH, Electrical Conductivity (EC), Total organic carbon (TOC), Nitrogen (N), Phosphorus(P) and Potassium (K)and microbial activity.
