| Bokashi is fermented organic compost capable of improving the physical, chemical, and biological conditions of the soils. The compost action in the agricultural production system is influenced by its preparation, resulting in products with different physicochemical characteristics. The study aimed to characterize bokashi produced on-farm and compare it with commercial products. The produced composts in southern Brazil were obtained through efficient microorganisms (EM), collected in an area of permanent preservation, and kefir. Two commercial composts were used for comparison (Plantae FertTM and Bokashi Sementes BrasilTM). Physical characteristics related to apparent specific gravity, water content, and water retention capacity and chemical characteristics... |

| En este trabajo se evaluó la germinación de semillas y el crecimiento de plantas de C. equisetifolia L. ante diesel, y su potencial de fitorremediación en combinación de bioaumentación y bioestimulación. La primera fase experimental evaluó el efecto tóxico de 15 dosis de diesel (0, 100, 250, 500, 800, 1000, 1500, 2000, 2500, 3000, 5000, 7500, 10000, 15000 y 20000 mg kg-1) en la germinación de semillas y la emergencia de plántulas. A los 10 días, la germinación fue mayor en concentraciones altas de diesel; la mayor geminación ocurrió en 20000 mg kg-1, y la menor se registró ante 5000 mg kg-1. La emergencia de plántulas fue mayor en las concentraciones menores a 5000 mg kg-1. A los 15 días, el crecimiento de las plántulas disminuyó ante concentraciones... |

| Considerando a predominância do uso de tanques de resfriamento coletivos no armazenamento do leite cru em Rondônia e a grande diversidade de microrganismos deletérios ao leite, o objetivo do trabalho foi avaliar a microbiota deteriorante do leite armazenado em 23 tanques coletivos da microrregião de Ji-Paraná e Cacoal. Para a contagem dos microrganismos utilizou-se semeadura em duplicata de 1 mL em placas de Petrifilm® AC aeróbios mesófilos e Petrifilm® EC coliformes totais de acordo com o fabricante. Para a contagem de psicrotróficos e termodúricos psicotróficos, as amostras foram semeadas em ágar padrão leite a 10%. Para a pesquisa de microrganismos termodúricos mesófilos e psicrotróficos, as amostras foram submetidas ao tratamento térmico (62,8 ± 0,5... |

| The author studies the microbial phenomena which occur during the maturation of French anchovies, some from the Basque, the others from the Roussillon coast. There are some differences in relation with the origin of the fishes. On a marine agar, the microflora of the Mediterranean ones is almost constant or in a light diminution while that of the Atlantic ones is climbing during 9 weeks before a decline. On an extremely salted agar and in the both origins the archaebacteria are increasing in number during 5 to 6 weeks and diminishing before. The complete ripening is obtained within 16-17 weeks. The limits of the significance of the microbiological analysis are discussed. |

| The changes in concentration of thiamine, biotin and vitamin B sub(12) in water of the soaked bottles for 6 h in situ in the north basin of Lake Biwa were examined successively over 30 hours. The concentrations of the vitamins changed comparatively during 6 h. soaking in situ. Generally, the concentrations of thiamine, biotin and vitamin B sub(12) were in high levels in the morning and in low levels in evening both in the soaked bottles and in the surrounding water. The fluctuation ranges in concentration of vitamins in a 5 m deep layer were greater than those in thermocline. From the data obtained with the soaked bottles in situ, it was supposed that the decrease of vitamins in concentration during the daytime surpass consumption of vitamins by... |

| There exists no biochemical test allowing to define the pathogenicity of a bacterium, still less for a Vibrionaceae. Two essential characters are to be retained to hold responsible an isolated germ, for an illness: 1) the binding factor, the identification is difficult but a double diffusion of agar should simplify the method; 2) the search for the choleric toxin or a common part of the choleric toxin (toxin LT or ST of E. coli ). Here again, simplified techniques may be used. The acquirement of a plasmid responsible for the binding factor or for the toxin production of the non-pathogenic Vibrionaceae in the origin of certain epidemic diseases in France and in the world. Frequently, epidemics due to common germs (Aeromonas hydrophila of Africa) lead to... |

| The Minimal Inhibitory Concentration (MIC) of a biocide is usually determined by adding it in various concentrations to a suitable growth medium which is then inoculated with the test bacterium. These cultures are then observed for up to 28 days for growth of the organism as shown by its production of black ferrous sulphide. A method has been developed whereby the MIC of a biocide can be found within 4 days. Instead of noting ferrous sulphide production, this new method measures changes in: 1) optical density and 2) sulphate reduction of a logarithmic culture of the test strain exposed to the biocide. |
