: World population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. In recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. In this study, single cell protein production was studied in a batch submerged culture using Aspergillus niger PTCC5012. Experimental design was ...

Research results at other locations in western U.S. indicate that a plant spacing of approximately 12 inches within rows and 20 or 22 inches between rows is necessary to obtain near maximum yields of sugarbeets (Beta vulgaris 1..) and yet maintain adequate space for machinery operation (4, 6, 10). 3 Increasing row and plant spacings with corresponding decreases in plant population have reduced ...

Cellulose is the most abundant biopolymer on earth, recognized as the major component of plant biomass. The cellulolytic microorganisms were isolated from gut of earthworm (Eisenia foetida). Using Glycerol asparagine agar media, the organisms were identified as Actinomycetes sps.. The endoglucanase activity of the culture broth was determined during actinomycetes growth by measuring the release...

background and objectives: lactobacillus delbrueckii ssp bulgaricus is widely used in dairy industries as a starter for yogurt production. this study was designed using response surface methodology (rsm) in 12 batch ph-controlled cultures of lactobacillus delbrueckii sub-ssp. bulgaricus for determining the effect of temperature and ph on the biomass production of a native strain of l. bulgaricu...

this research was conducted to study the effects of water deficiency stress, nitrogen application rates, and plant population on water use efficiency and nitrogen of oily sunflower in 2007-2008 agriculture and research center of west-azerbaijan. the study was consisted split-split-plot experiments using randomized complete block design with 3 replications. the factor main was consisted irrigati...

The infection of Aspergillus flavus and its aflatoxin production pose a severe threat to humans, animals as well as plants life. Their inhibition using green techniques are considered as one of the important challenges. The present study outlines the antifungal activity of the ZnO nanoparticles (NPs) synthesized from lemongrass leaf extract and their effect on the mycelial growth of <e...

This paper develops a production, recycling-disposal inventory problem over a finite time horizon in fuzzy and bi-fuzzy environments. The production and recycling process are performed in a plant which is located very near to the market. The products of the plant are continuously transfer to the market. Here, the dynamic demand is satisfied by production and recycling. The use units are collect...
