introduction more and better production of food is one of the necessities of today's world. since production of agricultural products of one region depends on the air and climatic factors, it is important to examine the role of climate in agriculture (mohammadi et al., 2004: 123). in relation to agroclimatology, numerous studies by different scientists and agricultural climatologists have ...

The paper presents the results of a study of cultural characteristics of the strain A/equine/Otar/764/07 (H3N8) of equine influenza virus isolated from sick horse during the outbreak of equine influenza epizooty in the Republic of Kazakhstan. The studies determined the optimal culture conditions for equine influenza virus strain A/equine/Otar/764/07 (H3N8) in MDCK cell culture. The optimal infe...

We demonstrated the feasibility of fedbatch operation using Clostridium acetobutylicum suspension culture as a biocatalyst for the continuous production of hydrogen. The optimum operating pH and temperature of the current cultivation system for hydrogen production were pH 6.0 and 37 degrees C, respectively. The volumetric loading of the bioreactor for hydrogen production can be as high as 650 m...

Rice straw hydrolysate was used as lignocellulose-based carbon source for Chlorella pyrenoidosa cultivation and the feasibility of in situ biodiesel production was investigated. 13.7 g/L sugar was obtained by enzymatic hydrolyzation of rice straw. Chlorella pyrenoidosa showed a rapid growth in the rice straw hydrolysate medium, the maximum biomass concentration of 2.83 g/L was obtained in only ...

Microalgae are considered promising sources of raw material for biodiesel production. The cultivation of microalgae for obtaining biomass depends on several factors such as the amount of available nutrients, CO2, water, light, temperature and pH. The literature suggests the use of alternative nutrients for reducing the environmental impacts of biodiesel production from microalgae. This study ai...
