Composting is associated with reclamation, recycling, treatment and disposal of wastes. Waste management remains the major concern for many industries for years. The process of treating organic waste has benefits such as improved sanitation production of renewable products less load in eco system and is an effective method of degrading organic waste containing hazardous compounds. The present study deals with the conversion of waste organic products into a useful by product, compost which is used to enhance growth of crops with combinations of microorganisms. The physical characteristics such as temperature, pH, ash content, moisture content, carbon content and C: N ratio was determined at every 15 days interval. The microbiological characteristics such as standard plate count, biochemical and physiological tests were done to identity and characterize strain according to Bergey's manual of determinative Bacteriology. The micro flora analysis explains the micro biota at various stages with different characteristic degrading ability. The study reveals the efficiency of these organisms as plant growth promoting rhizobacteria (PGPR). Combinations of microorganisms with compost act as a good biofertilizer which improves the fertility of soil and increases plant growth. Better results are produced by mixed organisms like Azospirillum, Rhizobium and Pseudomonas (T4). The least growth was found in the inoculation of Bacillus and Azotobacter with soil. Based on this study we conclude that the rhizospheric organisms play well as plant growth promoting agents and gives a better yield and growth of plants. It also increases the fertility of soil and does not cause any pollution to the environment and can be commercialized for organic farm practices.

In the present investigation, an attempt was made to develop a treatment system for the simulated atrazine wastewater using a hybrid upflow anaerobic sludge blanket (HUASB) reactor. The reactor was operated for 90 days in three phases. In phase-I (0–25 days), acclimatization was done with the acclimatization media. In phase-II, (26–72 days), the experiment was carried out to find out the effect of atrazine and sucrose concentration 24 h HRT. Maximum atrazine reduction was observed when influent sucrose concentration was 300 mg/l and atrazine concentration of 5mg/l, among the various combinations of influent sucrose and atrazine. The gas production rate increased with increase of the sucrose concentration from 300 mg/l to 1000 mg/l. Maximum biogas production rate of 473 ml/d was recorded when the atrazine and sucrose influent concentrations were maintained at 25 mg/l and 1000 mg/l respectively. In phase-III, for 12 h HRT, the steady state COD removal efficiency and atrazine degradation efficiency were 70% and 59% respectively, for the wastewater containing 5 mg/l of atrazine and 300 mg/l of sucrose. From the SEM observation of sludge granules, two species of methanogens, namely, Methanosarcina spp., and Methanobacterium spp. were identified.

Green nanoparticle synthesis has been achieved using the extracts of leaves/stem/roots of mimosa (Mimosapudica) as the reducing and capping agent. The study utilizes the highly pernicious and otherwise worthless terrestrial weed mimosa. Nanoparticles were rapidly synthesized at ambient temperature and shape/size control was made possible by controlling the extract: metal proportions. The results of UV-visible spectrophotometric, Fourier transform infrared, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy support the biosynthesis and characterization of the nanoparticles. One of the distinguishing features of the study is that it employs the whole plant unlike most previous studies which are confined to the use of leaves.

The atmospheric fungal spores are an ever-present component and well known particulate matter to trigger asthma and hay fever symptoms in atopic individuals. The hospital atmosphere near Chennai central, Chennai, Tamilnadu has been monitored for airborne fungal spores at several sampling stations by Petri-plate settlement method. In qualitative and quantitative way, fungal spores considerably varied from season to season. The proposed study involved the examination of the antimicrobial activity of Penicillium spp and correlated with meteorological data recorded during the study period. The bioactive compounds of Penicillium spp of hospital environment at different sites of different seasons were extracted and then subjected for its antimicrobial activity study with different bacterial pathogens. The activity was also compared using different antibiotic discs (Tetracycline, Vancomycin, Ampicillin, Amoxicillin and Penicillin-G). The Penicillium spp isolated from hospital environment during winter season showed good activity against the pathogens than the other seasons.

Improper discharge of colored effluents in aqueous ecosystems depicts acute toxic effects on aquatic flora and fauna and causing severe environmental problems worldwide. The present study concentrates on efficiency and potentiality of novel strain SBU7 capable of degrading the azo textile dye Mordant Black 17, which was isolated from effluent disposal sites of textile industries, Tirupur. Phenotypic characterization and phylogenetic analysis of the 16S rRNA sequence indicated that the bacterial strain-SBU7 belonged to Pseudomonas aeruginosa. The strain was able to decolorize the azo dye (Mordant Black 17) efficiently up to 86% and 75% in shake and static conditions respectively, in a range of 100 mg L−1, at temperature of 37 □C, at pH 7.0. The spectrophotometric analysis of n-butanol cell extract authenticated the decolorization of dye was obtained because of the degradation of aromatic amines rather the inactive surface adsorption which is further substantiated with TLC and FTIR.
含水生态系统中有色废水的不当排放对水生动植物造成了严重的毒性影响，并在世界范围内造成了严重的环境问题。本文研究了一种新型菌株SBU7对印度蒂鲁普尔纺织工业废水处理场所分离的偶氮纺织染料媒染剂Black 17的降解效率和潜力。表型鉴定和16S rRNA序列的系统发育分析表明，菌株sbu7属于铜绿假单胞菌。在100 mg L−1、温度37□C、pH 7.0的条件下，该菌株对偶氮染料(Mordant Black 17)的脱色效率分别达到86%和75%。对正丁醇细胞提取物的分光光度分析证实了染料的脱色是由于芳香胺的降解而非非活性表面吸附，并通过TLC和FTIR进一步证实了这一点。

The term osteo- derived from the Greek word osteon, meaning bone, myelo- meaning marrow, and -itis meaning inflammation) simply means an infection of the bone or bone marrow. It can be usefully sub classified on the basis of the causative organism (pyogenic bacteria or mycobacteria), the route, duration and anatomic location of the infection. The aim of the study is to develop the analytical method for the dissolution release of sodium fusidate tablets from it's formulation by HPLC. The dissolution release of this formulation is compared with the Innovator sample Fusidin. The similarity factor (F2) and the difference factor (F1) was evaluated with comparative dissolution profile by comparing the results obtained with our preparation and the marketed innovator preparation. A HPLC method has developed for this formulation and the dissolution profile in 3 different media (pH6.8, 7.0 and pH 7.4) at various time points was estimated.

The eco-friendly management in the hotel industry is a practice of operating hotels through green technology. The hotel that uses the resources wisely; reduces the consumption of water and energy; produces minimum waste and recycles the waste; and has less impact on the environment is termed as a Green Hotel. The green hotels are aimed to save resources; reduce pollution and operating cost; increase profit margins; and support the Ecotourism. The ecotourism relies on unpolluted natural environment which in turn contributes for the country's economy. This paper focuses on the green technology to be practiced in hotel industry for the environmental sustainability. The implementation of energy and water conservation projects, zero waste approach and management of solid waste disposal are the key factors of the sustainable development. The primary energy technologies recommended for the hoteliers are the lighting systems; heating, ventilation and air-conditioning systems (HVAC); variable speed drives; and energy management systems. To reduce the consumption of water the hoteliers should install low flow shower heads, sensor activated kitchen taps, and drainage barriers around pools; replace all toilets with ultra-flow toilets; switch from water cooled to air-cooled ice machines; use AAA rated front loading washing machines; and consider alternative sources of garden watering such as rainwater, treated grey water and cooling tower effluent. The hotel staff should be trained to collect the recyclable materials from the hotel waste stream through recycling program. The insitu composting and biomethanation are the best practices of managing the waste generated by the hotels.

Activated carbon prepared from agro waste cocoa (Theobroma cacao) shell has been utilized as the adsorbent for the removal of Reactive blue 2 dye from aqueous solution. Adsorption studies were carried out at different initial concentration and contact time, pH of solution and temperature. Adsorption data were modeled using Langmuir, Freundlich, Tempkin and Dubinin-Raduskevich isotherms. Based on correlation coefficient (r2) values, equilibrium data found fitted well to the Langmuir isotherm. Adsorption kinetics was verified by pseudo-first order, pseudo-second order and Intraparticle diffusion models. The kinetic adsorption data fitted the pseudo-second order kinetic model well and also followed the intra-particle diffusion model. Thermodynamic parameters such as ΔH°, ΔS°, and ΔG° were evaluated. The positive enthalpy shows that the adsorption process was endothermic in nature.
