Naresh Kumar, Sukhvinder Singh Purewal and Amandeep Singh Thind
Dyes are most widely used by various industries such as textile, paper, cosmetics, and pharmaceuticals. When these dyes are discharged as a waste in rivers and open environment it creates problem to fauna and flora. Although various physical and chemical methods have been used for emoval of dyes from waste but these methods are expensive and sometimes produce secondary pollutants. Biological methods have been used for decolorization of dyes. Various microorganisms such as bacteria, fungi and actinomycetes have been reported to decolorize dyes. Out of these, fungi have shown great potential for decolorization by bioadsorption and biodegradation. Present work focused on decolorization potential of Aspergillus awamori (MTCC-548) against brilliant green dye. It was found that this fungus showed potential for decolorization of brilliant green dye.

Solid waste management is becoming a major problem in developing countries like Pakistan due to its increasing volume and poor management. To minimize these problems waste should be handled according to its sources, as different sources produce different types of waste. Keeping this in perspective a study on the assessment and planning of solid waste management practices was conducted in Government College University, Lahore (GCU). Categorization and quantification of different categories of waste generated by GCU students was made and their knowledge, attitude and opinion were assessed using a questionnaire. The results showed that GCU produced 644 Kg/day of solid waste out of which organic waste was more in amount (44%) followed by Paper (13%), Plastic (11%), Glass (7%) and Metal waste (9%). Total recyclable waste produced from GCU Lahore was found to be 200 Kg/day. Science students and particularly environmental science students had more Knowledge and a positive attitude as compared to humanities and Non-Environmental science students respectively. A non-significant relationship of Gender was found with knowledge while female students had a more positive attitude towards solid waste management compared to male students. The mean score of knowledge and attitude of GCU Lahore’s students was found to be 0.53 and 0.62 respectively on the scale of 1. It was also found that knowledge and attitude of the students were highly correlated. It was suggested to introduce source separation and recycling in the University, by doing so environmental benefits and revenue can be generated. This research is expected to provide possible data which can be useful during planning and policy making by University authorities.

Mushroom is a food of high quality flavour and nutritional value, high content of protein, high content carbohydrates, low in fat and cholesterol. Effect of supplements on the yield and nutritional value of oyster mushroom (Pleurotus sajorcaju) was investigated in this study. Wheat bran, lime and sugar were used as supplements which were varied into five treatments. The first treatment (T1) consisted of wheat bran, lime and sugar, second treatment (T2) consisted of wheat bran and lime, third treatment (T3) consisted of wheat bran only, fourth treatment (T4) consists of lime only and fifth treatment (T5) consists of wheat bran and sugar. Each of the substrate contained 1kilogram of substrate per bag. The produce of the mushroom; mycelia growths, diameter of the pileus, length of stipe, mushroom height, mushroom yield as well as proximate analysis of the mushroom were analyzed. The moisture content (%) ranged from 72.51-78.40%. The protein content ranged from 26.28- 29.61% across the five treatments. According to the result, the five treatments attained full ramification stage (100%) at fourth week. The analysis of variance carried out showed significant different (P≤0.05) in yield (g/kg) of mushroom across the treatments. Hence, T1 had the highest yield followed by T2, T4, T3 and T5 with mean yield values of 138.74±7.87, 90.76± 4.62, 88.66 ±3.48, 62.15 ±1.19 and 49.04 ±2.02 (g/kg) respectively. The results of the biological efficiency (BE) obtained ranged from 32.52-82.54% across the five treatments. The length of stipe, diameter of pileus and mushroom height obtained showed that values obtained were good and sizeable. The result further showed that T3 and T5 were unable to produce up to fifth harvest while T1, T2 and T3 were able to produce till fifth harvest. Hence, the implication is discussed.

Catalytic liquid - phase oxidation process was investigated in laboratory – scale experiments for the treatment of organic pollutants in industrial waste water. The effect of the operating conditions on COD reduction of organic pollutants including temperature, reactor pressure, residence time and pH were studies. The experimental results indicated that the COD reduction of organic pollutant is too high with catalytic oxidation process using the Platinum on activated carbon (2% Pt/AC) catalyst. This heterogeneous catalyst was found to be very effective in the complete degradation of organic pollutants. Approximately 98.85% Chemical Oxygen Demand (COD) reduction was achieved by catalytic liquid- phase oxidation over 2% Pt/AC catalyst at 37 kg/cm2 reactor pressure and 220 0C temperature. This process provides an environmentally attractive option to eliminate hazardous organic waste water problem and shows the significant potential for the treatment of organic pollutant in industrial wastewater.
Comparative Study of Transpiration Rate in Mangifera indica and Psidium guajawa Affect by Lantana ca
Ravindra Singh, Sadhana Chaurasia, Anand Dev Gupta, Arpana Mishra and Prabhat Soni
Water is very precious to life. Save each drop of water can give a life to someone. Some losses of water take place from the surface of earth to the atmosphere by evaporation and transpiration. Transpiration is a process of water loss from arial parts of plant. Plants absorb water from the soil for their growth and metabolic activities but only 1% is used in these processes and 99% water transpired in atmosphere. These losses can be reduced by the using Lantana camara extract as an anti transpirent. Present study shows that as the concentration of the extract increases, the transpiration rate decreases this is inversely proportionate to concentration of extract. Closed number of stomata’s increases with increasing concentration. Therefore Lantana extract can be used as an anti transpirent. Mangifera indica is more sensitive to aqueous extract of Lantana camara than the Psidium guajawa.

Use of industrial and domestic wastewaters for irrigation has been becoming a public health concern throughout the developing countries. It is a common practice in Pakistan to use industrial and sewage effluents to irrigate crops and vegetables. In this study an atomic absorption spectrophotometer was used to measure cadmium, chromium, copper, nickel and lead concentration in vegetables irrigated by effluent from Hudiara drain. Dry ash method and wet digestion method were used for analysis of heavy metal contents. Results showed that maximum concentrations of heavy metals were found in mustard leaves and turnip by dry ash method and wet digestion method respectively. Maximum concentration of heavy metals detected by dry ash method was of Cu (0.31ppm) in mustard leaves, Cr (0.12ppm) in coriander, Pub (0.22ppm) in mustard leaves and Ni (0.07ppm) in peas while by wet digestion method, it was of Cu (0.8ppm), Cad (0.02) in all vegetables, Cr (0.14ppm) in peas, Pub (0.21ppm) in spinach and Ni (0.03ppm) in mustard leaves. Though the heavy metal concentrations in selected vegetables were within WHO/FAO permissible limits but these can cause deleterious health effects in people on utilizing these vegetables repeatedly. Statistical analysis showed that there was a significant difference in detection of heavy metals in various vegetables by dry ash method and wet digestion method.

Due to change in resistance between thundercloud top and the atmosphere, variation of current is produced in the global atmospheric electric circuit, which produces a change in conductivity. Modulation of cosmic ray due to solar influence leads to changes in earth’s electric field and thereby on thunderstorm activity.As conductivity is proportional to ion density and also the ion density is proportional to the square root of the production rate, Ionization of the upper atmosphere changes inversely with solar activity.
