The UASB reactor (35 degrees C) was quite efficient for removal of bulk COD (62-67%) even for such high strength and recalcitrant wastewater as the cultivation medium from the first separation process of baker'syeasts (the average organic loading rates varied from 3.7 to 10.3 g COD/l/d). The aerobic-anoxic biofilter (20 degrees C) can be used for removal of remaining BOD and ammonia from strong...

Background: An economical and integrated high-throughput primary screening strategy was developed for high-aerobic microbe Monascus purpureus cultivation. A novel and effective mixture culture method was proposed and used to realize the whole mutant library being high-throughput screened after mutagenesis. Results: The good correlation of fermentation results between differing-scale cultivation...

Topsoil samples were collected from eight golf courses in Yamaguchi Prefecture, Japan, and enrichment cultures were carried out with a basal-salt medium containing 0.2% 4-tert-octylphenol polyethoxylate (OPPEO) as sole carbon source. OPPEO-degrading activity was detected in one of the samples, from which a strain of OPPEO-degrading bacterium was isolated. The isolated bacterium grew on a nutrit...

In recent years, traditional landraces are gaining importance due to its many health benefits. But the main drawback of rice variety is low productivity with increased water consumption. Therefore different establishment methods be evaluated. weed infestation occurs in every method. Hence present study aimed dynamics by evaluating water-saving technologies compared puddled transplanting using v...

A field experiment was carried out to identify the best suitable rice variety for aerobic cultivation in Cauvery delta region. Ten ruling varieties were sown two consecutive Kharif seasons, with regular nutrient and weed management practices under condition. Growth parameters viz.,plant height, leaf area index, root length dry weight studied. Similarly yield viz., panicles m-2, Dry matter produ...

Abstract Aerobic granular sludge (AGS) is known as excellent biological treatment for wastewater industry, high organic load and adsorption of heavy metal. AGS have some advantages such higher density, biomass retention, simultaneous nutrient removal tolerance to toxicity. The aim this research use sequencing batch reactor (SBR) cultivate in the short time (28 days) laboratory scale. Experiment...

Aerobic and respiratory cultivations provide benefits for some lactic acid bacteria (LAB). Growth, metabolites, enzymatic activities (lactate dehydrogenase; pyruvate and NADH oxidases, NADH peroxidase; catalase), antioxidant capability and stress tolerance of Lactobacillus casei N87 were evaluated in anaerobic, aerobic and respiratory (aerobiosis with heme and menaquinone supplementation) batch...
