Arthrobotrysamerospora (ATCC 34468) produced glucoamylase in a semi-synthetic medium containing starch as a sole carbon source. Polyacrylamide gel electrophoresis of crude glucoamylase showed three isoenzymes. They were designated as glu I, glu II and glu III according to their electrophoretic mobility. These iso-glucoamylases were purified by column chromatography using DEAE-Sephadex A-50. The...

Compost production is a critical component of organic waste handling, and compost applications to soil are increasingly important to crop production. However, we know surprisingly little about the microbial communities involved in the composting process and the factors shaping compost microbial dynamics. Here, we used high-throughput sequencing approaches to assess the diversity and composition...

Studies of fungi in upland cotton (Gossypium hirsutum) cultivated in the United States have largely focused on monitoring and controlling plant pathogens. Given increasing interest in asymptomatic fungal endophytes as potential biological control agents, surveys are needed to better characterize their diversity, distribution patterns and possible applications in integrated pest management. We s...

B-Dere is one of the communities in Ogoniland and a major oil producing area Rivers State where exploration production activities commenced 50 years ago now characterized by fields installations that have remained dormant for several decades. Past spills, lack maintenance, trapping damage to infrastructures been common sight this region environment has without remediation over years. community ...

Central retinal vein occlusion (CRVO) with capillary non-perfusion predisposes to retinal neovascularisation and rubeosis iridis (Laatikainen and Kohner, 1976). Studies on diabetic retinopathy suggest that destroying large areas of hypoxic retina or reducing its metabolic demands prevents neovascularisation and may cause retinal vessels to regress (Taylor, 1970). It was therefore decided to try...

Subterranean termites are important structural pests in much of North America, and worldwide. Recent studies of eastern subterranean termite (Reticulitermes flavipes [Kollar]) colonies in Ontario, Canada, indicate that these colonies contain greater foraging populations and forage over larger territories than was previously thought to be the case. These results are consistent with those obtaine...
