Abstract: The most severe corrosion due to bacterial activity in pipe steel for the transportation of water and the injection systems is influenced by sulphate reducing bacteria (SRB), thiosulphate reducing bacteria (TRB) and others microorganisms. In the aim to reduce the impact of bacterial corrosion, steel pipes were substituted by fiberglass pipes. These types of materials are very resistant to corrosion and the life of use was prolonged. Fiberglass pipes are used for the water transportation that be used for the water flooding systems in the oil fields and fire systems. During the opening of a section of the fiberglass line, the scale found inside this line, produced a smoke that was followed by a fire that provoked the inflammation of the fiberglass. Also, the aim is to understand the phenomena and a suspicion of the role of some bacteria in this phenomenon. The identified bacteria in all the samples show the presence of sulfate-reducing bacteria, methanogenic bacteria and fermentative bac

Abstract: Tomato leaf curl virus disease (ToLCVD) is one of the major causes for maximum yield loss of tomato. This disease is caused by tomato leaf curl viruses (ToLCV) belongs to the genus Begomovirus. The infected plants emerge with severe leaf curling, puckering, and yellow margin, reduced leaf size and stunted growth. Tomato leaf curl symptoms caused due to physiological reason sometimes may misguide the farmer for proper identification. In this study, we described about the molecular diagnosis of ToLCVD in the samples collected from six major tomato cultivating areas of Bangladesh. Molecular methods were followed to diagnose and characterize tomato leaf curl virus coat protein (CP) gene. We have isolated total DNA from symptomatic leaves and subjected to rolling circle amplification (RCA). Restriction digestion, polymerase chain reaction (PCR) and sequencing was performed using the RCA products. The coat protein of ToLCV was sequenced by the begomovirus specific “BGCP” forward and reverse
