Comparison of Lactic Acid Isomers Produced by Fungal and Bacterial Strains
Many organisms produce lactic acid by fermentation, but most industrially important strains are from the genus Lactobacillus and Rhizopus oryzae. L(+)-Lactic acid is the only optical isomer for use in pharmaceutical and food industries because human body is only adapted to assimilate this form. In this research, six strains of Lactobacillus and four strains of R. oryzae (known as high producer)...
متن کاملMicrobial removal of engine oil from polluted media (the case study: Hamadan City)
Discharging industrial wastes into the soil causes accumulation of pollutants, especially petroleum hydrocarbons and used engine oil, in the environment. This study was done to find some bacterial strains capable of removing the engine oil from contaminated soils. Soil samples contaminated by engine oil were collected from some polluted area of Hamadan City, and then their bacterial strains wer...
متن کاملCharacterization and Phylogenetic Analysis of Magnaporthe spp. strains on Various Hosts in Iran
Background: Populations of Magnaporthe, the causal agent of rice blast disease, are pathotypically and genetically diverse and therefore their interaction with different rice cultivars and also antagonistic microorganisms are very complicated. Objectives: The objectives of the present study were to characterize phylogenetic relationships of 114 native Magnaporthe strains, isolated from rice a...
متن کاملEffects of Bacterial Strains to Inhibit Growth of Phytophthora pistaciae under Different Electrical Conductivities
Root and crown rot (gummosis) is known as the most destructive disease affecting pistachio in Iran. The efficiency of bacterial strains to reduce the growth rate of Phytophthora pistaciae was studied under different electrical conductivities (EC, 0, 2, 4, 8, 12 ds/m). Soil and rhizosphere samples were collected from pistachio growing regions in Kerman province, Iran, during 2011 - 2012. Overall...
متن کاملIdentifying Tomato Wilt disease and Controlling It Using Antagonist Bacteria in East Azerbaijan Province
Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive diseases which negatively affect the tomato production worldwide. Considering the importance of the disease, using biological control agents could be effective approaches in reducing the damage of the pathogen. Tomato samples of suspected bacterial wilt disease were gathered from different regions of East Azarbayjan....
