We estimated carbon and nitrogen stocks in aboveground biomass (AGB) and belowground biomass (BGB) along an elevation range in forest sites located on the steep slopes of the Serra do Mar on the north coast of the State of São Paulo, southeast Brazil. In elevations of 100 m (lowland), 400 m (submontane), and 1000 m (montane) four 1-ha plots were established, and above- (live and dead) and below...
Microbial lipid production by the oleaginous yeast Cryptococcus sp. was studied using glucose and cellulosic hydrolysate as carbon source, to realize the feasiblility of biodiesel production from high-lipid cell culture. The crude lipid contents of Debaryomyces nepalensis and Cryptococcus sp. cultured in YM Agar reached as high as 32-35 % on dry weight basis, which were higher than those of Pse...
Marine bacterioplankton were isolated and grown in batch cultures until their growth became limited by organic carbon (C), nitrogen (N), or phosphorus (P). Samples were taken from the cultures at both the exponential and stationary phases. The elemental composition of individual bacterial cells was analyzed by X-ray microanalysis with an electron microscope. The cell size was also measured. The...
A laboratory-scale completely autotrophic nitrogen removal over nitrite (Canon) biofilm reactor was applied to remove nitrogen and organic carbon from swine digester liquor for 150 d. A stable nitrogen removal rate was reached after a three-week adaptation period. The nitrogen loading rate of influent were 0.20±0.04, 0.26±0.04, 0.26±0.07 kg N m(-3) d(-1) in period I, II and III, respectively. N...
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which shall be separately managed from livestock manure due to the negative impacts of manure nutrients and harmful effects on down-stream of livestock manure process with respect to the microbial growth. Simultaneous nitrification and denitrification (SND) is corresponded by the inhibition of second n...
Light and temperature are two particularly important environmental cues for plant survival. Carbon and nitrogen are two essential macronutrients required for plant growth and development, and cellular carbon and nitrogen metabolism must be tightly coordinated. In order to understand how the natural light/dark cycle regulates carbon and nitrogen metabolism in rice plants, we analyzed the photosy...
A home electrical composter has arisen as a popular tool to expedite the lengthy composting process. It been conveniently selected compost producer in kitchen households and is especially favoured urbanized settings. The generated composts from composter, however, are still found be immature would require additional curing. quality of can improved by investigating initial carbon-to-nitrogen rat...
Background : Nitrogen-containing ions such as nitrate and nitrite occur widely in a variety of water sources. This pollutant causes health problems such as the blue-baby syndrome, and possible formation of carcinogenic compounds in the digestive tract. Thus, removing them from water sources seems necessary. Biological denitrification is a method used in the treatment of nitrate contaminated wat...
