Bioactivity assessment of endophytic fungi associated with Centella asiatica and Murraya koengii Archana Nath, Jyoti Pathak SR Joshi
BACKGROUND The present work investigates the impact of discharges from a storm water sedimentation basin (SSB) receiving runoff from a connected motorway in southern Germany. The study lasted for almost two years and was aimed at assessing the impact of the SSB on the fauna of the Argen River, which is a tributary of Lake Constance. Two sampling sites were examined up- and downstream of the SSB...
The objective of this review is to synthesize information available on the feeding value of coffee waste. In the diets of ruminants, waste and by-products of coffee have successfully used 10 to 30%. It has been claimed that the feeding of Coffee leaves extends the lactation period. Coffee pulp (dried or not), coffee hulls (sticky or dried) and coffee grounds (a by-product of instant coffee manu...
background: in natural waters and/or aquaculture facilities, fish are often exposed to chromium waste and demonstrate cumulative deleterious effects. to our knowledge, there are no studies concerning the effects of trivalent cr on c. carpio hematology. this study presents hematological and some biochemical parameters of common carp, cyprinus carpio, affected by sublethal concentration of trival...
We studied the hygroscopic properties of gelatin from waste-products after processing common fresh-water fish species form Astrakhan region (skin, scales, bones, fins, and cartilage) as an object drying. The analysis thermodynamics internal mass transfer was carried out during interaction substance specified product with water. objects study were concentrates obtained by convective-radiation dr...
Biofloc technology (BFT) is a relatively new biotechnological means to support high density culture, maintain water quality, biosecurity, reduce the need for water exchange, reutilize the feed and reduce the production cost. This technology is mainly based on the principle of waste nutrients recycling (particularly nitrogen) into microbial biomass that can be used in situ by the cultured animal...
