The present review article aims to highlight various pretreatment technologies involved in the biochemical conversion of biomass to bioethanol from lignocellulosic biomass without the process modification. Pretreatment technologies are aimed to increase the enzyme susceptibility to the biomass for high yield of ethanol production through microbial fermentation. Broadly, pretreatment methods are divided into four categories including physical, chemical, physico-chemical and biological. This paper comprehensively reviewed on the lignocellulosic biomass to bioethanol process with focuses on pretreatment methods, their mechanisms, combination of different pretreatment technologies, the addition of external chemical agents, advantages, and disadvantages. It also discussed the ethanol productions from biomass in details without disturbing the process integrity.

The chromium nitride thin layers have became more and more popular in the last decade because of their good physical, chemical and mechanical properties. The present study deals the morphological characterization of hard Cr-N and CrAlN thin layers deposited on silicon (100) substrates by physical vapour deposition (PVD). The effect of the annealing temperature on the adherence and the thermal stability of CrN layers are considered. SEM observations and EDS microanalyses were performed. Cr-N films, 1μm thick, were annealed for 1 hour at 600 to 1000°C under flux of nitrogen. These layers presented a good thermal stability at low temperatures. Moreover SEM observations showed that the CrN films had a low adhesion at high temperatures. In addition, after annealing at 700°C for 4 hours, CrAlN coating of 1μm thickness presents a better thermal stability than CrN coating but with lower adherence. The results given by SEM-EDS and XRD are compared.

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

The different integrated production systems can directly interfere with its bacterial community. The present study aimed to assess density, bacterial diversity and the influence of dry and rainy season in different integrated and an exclusive production system. The fallow and a native forest area was assessed to. Samples were collected in 2012 March and September. The isolation were carried out into Petri dishes containing DYGS medium. The number of colony forming units (CFU) was counted after 48 hours and. The bacterial density ranged between 106 and 107 CFU g-1 soil. The crop system affected the dynamics of the bacterial community only in the rainy season. The rainy season showed greater density of total bacteria when compared to the dry period regardless of the cropping system. The dendrograms with 80 % similarity showed thirteen and fourteen groups in the rainy and dry seasons. Isolates with the capacity to solubilize phosphate in vitro were obtained from all areas in the two seasons, but this feature has been prevalent in bacteria isolated during the rainy season
