This document discusses microbial identification methods. It begins by outlining the objectives and topics to be covered, including identification of bacteria, fungi, algae, and viruses. For bacteria, it describes phenotypic methods like morphology, physiology/biochemistry, and genotypic techniques using genetic markers. Morphological identification of bacteria involves shape, staining, and colony appearance. Physiological/biochemical tests examine enzyme production and nutrient metabolism. Genotypic methods like nucleic acid sequencing and PCR are also discussed. The document continues by addressing identification of fungi, algae, and viruses through their distinguishing characteristics and laboratory techniques.

Methanogenesis or biomethanation is the formation of methane by microbes known as methanogens. Organisms capable of producing methane have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria.

Over 360,000 homes on Long Island have inadequate wastewater treatment technologies. Long Island
recently revamped their onsite wastewater treatment laws to mitigate this environmental degradation
from septic systems. This seminar will present information about the advanced wastewater treatment
technologies that significantly reduce the impact of nitrogen on the environment. The presentation will
focus on the role of aerobic treatment technologies and other advanced onsite wastewater treatment
technologies.
Effects of Fungicides for Non Target Fungi Alternaria cassiaeIJEAB
The fungicides are used to control of pathogenic fungi in several tilth but they can affect negatively the microorganisms diversity of soil. The aim of this research was to evaluate the toxicity and environmental risk of tebuconazoles: captan, tebuconazole and the mixture chlorothalonil + propamocarb hidrochloride for fungi Alternaria cassiae. Each fungicide were performed three experiments in completely randomized design with three repetitions and the growth was evaluated daily. Inhibition concentration (IC50;7d) of tebuconazole was 3.49 mg L-1, the captan was 47.36 mg L-1 and of mixture chlorothalonil + propamocarb hidrochloride, 64.04 mg L-1. Tebuconazole is classified as moderately toxic and sensitivity, captan, low toxicity and sensitivity and the mixture, non toxic and insensitive but only captan showed possibility of adverse effect for A. cassiae.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
