1. Desempenho de wetlands construídas (banhados construídos) no tratamento de manipueira
The objective of this research was to assess the possibility of applying subsuperficial flow constructed wetlands to lower the pollution load from cassava processing wastewater (cassava wastewater) and to produce Green biomass. The study was performed at lab-scale by using 4 glass units, with fine sand as substrate, where 3 units were cultivated with Tangola

2. Ecofisiologia de Cyatheaceae (Monilophyta): fenologia, banco de esporos, anatomia e germinaÃÃo
The objective of this study was: to define the fenolÃgico standard of the species of Cyatheaceae, to evaluate the formation of the bank of spores of Cyatheaceae in the of Atlantic Forest of the RPPN of Frei Caneca, to the long one of the year, to define excellent conditions of growth of the species, and also to define anatomical standard of fronds of two sp

3. Use of Membrane Filter Technique in the Microbiological Control for the Brewing Industry
A physical method was developed involving serial filtration with membrane filters for separating yeast cells from bacteria. Such a method eliminates the need for antibiotics previously required to permit differential counting of such populations. All yeast cells filtered were successfully retained and cultivated on a 1.2-μ membrane filter by use of a synthe

4. Relationship Between Sexuality and Carotene Synthesis in Blakeslea trispora
When stimulated by equivalent amounts of progametangia-inducing hormones, cultures of the minus mating type of Blakeslea trispora produce about the same quantities of carotenoids as mated cultures of the fungus, which suggests that the stimulation of carotene synthesis during the sexual activity of mated cultures is the result of hormonal action. These hormo

5. Separation of Viable Rickettsia typhi from Yolk Sac and L Cell Host Components by Renografin Density Gradient Centrifugation
Rickettsia typhi cultivated in the yolk sac of chicken embryos or in L cells irradiated 7 days previously was separated from host cell components by two cycles of Renografin density gradient centrifugation. Preliminary steps involved differential centrifugation and centrifugation over a layer of 10% bovine plasma albumin of infected yolk sac suspensions, or

6. Immunological and biological characterization of Coxiella burnetii, phases I and II, separated from host components.
Coxiella burnetii, phase I and II, cells cultivated in the yolk sac of chicken embryos were separated from host cell components by two cycles of isopycnic Renografin gradient centrifugation. Initial steps in the purification of viable C. burnetii involved differential centrifugation and sedimentation through an aqueous solution of 30% sucrose and 7.6% Renogr

7. Effects of Natural Intensities of Visible and Ultraviolet Radiation on Epidermal Ultraviolet Screening and Photosynthesis in Grape Leaves1
Grape (Vitis vinifera cv Silvaner) vine plants were cultivated under shaded conditions in the absence of ultraviolet (UV) radiation in a greenhouse, and subsequently placed outdoors under three different light regimes for 7 d. Different light regimes were produced by filters transmitting natural radiation, or screening out the UV-B (280–315 nm), or screeni
