Under appropriate growth conditions, white rot fungi like Ganoderma lucidum produce Lignin Peroxidase (LiP) as one of the extracellular oxidative enzyme that can oxidize a wide range of naturally stubborn musky pollutants. However, some important drawbacks are experienced in employing free enzymes, including unstable activity under working conditions and separation of the enzyme from reaction product. Technology in which enzyme attached to solid support has proofed an operative solution to these issues. Immobilization improves enzyme catalytic assets and functioning stability and assists enzymes various salvage, parting, and continuously automatic operations in industrial production. In this project lignocellulosic agro-industrial waste material, wheat straw was used as carbon source and solid support for LiP production by an native WRF strain Ganoderma lucidum IBL-05 through solid state fermentation under pre-optimized growth conditions. to 3.1 to 7.9fold and 2213.78 U/mg specific activity. The presence of single band (38 kDa) on sodium dodesyl sulfate gel electrophoresis define that the LiP was monomeric single aminoacid chain. Partialy purified LiP was immobilized by adopting different immobilization techniques like Ca-alginate beads, chitosan beads, silica gel, activated animal charcoal, alginate-chitosan microencapsules and CLEAs. The influence of temperature, pH, and substrate concentration on free and immobilized LiP was investigated to determine the effect of immobilization on LiP activity and stability. Silica (93%) was the best support in which LiP gave maximum immobilization efficiency. Energy-Dispersive X-ray spectroscopy (EDX) was done for conformation of immobilized LiP in the support. Results of EDX showed that LiP was successfully immobilized in different support material. The immobilized LiP was used for degradation of textile dyes and textile effluents. Maximum textile dye removal was done by activated animal charcoal (95%) and maximum textile industry effluents decolorization was done by silica (98%). Immobilized LiP was more effectual decolorizer of selected textile dyes and practical textile industry effluents.

آنکھوں کو بھلے لگتے ہیں آثار نبیؐ کے

آنکھوں کو بھلے لگتے ہیں آثار نبیؐ کے
ہر سمت ہیں بکھرے ہوئے انوارنبیؐ کے

در پیش ہے پھر مرحلہ خیبر و مرحب
پھر آئیں نظر حیدرِ کرارؓ نبیؐ کے

دونوں ہی دل و جان سے قربان تھے اُن پر
مکے کے مہاجر ؓ ہوں کہ انصارؓ نبیؐ کے

بو بکرؓ و عمرؓ ، حیدرؓ و عثمان ِ غنی ؓ تک
ہیں قابلِ اکرام سبھی یار نبیؐ کے

دل ہو کہ دماغ اِن سے منور ہیں ہمہ دم
آنکھوں کا اُجالا ہیں یہ افکار نبیؐ کے

اِن کے ہیں مکیں آیۂ تطہیر کے مالک
ہیں کتنے مقدس در و دیوار نبیؐ کے

سوچیں تو نہیں آتے ہیں گننے میں بھی عابدؔ
اُمت کے لیے اتنے ہیں ایثار نبی ؐ کے

طبی میدان عمل میں ضرورت کی بنیاد پر رخصت کا اطلاق

This research article discusses optimal concessions (Al-Rukhsa) in light of the views of Jursists  in medical context. The study adopted an analytical method to analyze Quranic Verses, Ahadith and the principles of Fiqh and reliable classical juristic writings  related to this particular topic. The study came up with several results and one of the important results is the emphasis on the permissiblity of the idea of looking for the optimal concessions to be acceptable if certain conditions and criteria are duly fulfilled. It also conclude that the reforms of islamic laws as well as juristic thoughts in the modern era can not oppose the Islamic fundamentals related to the idea of religious information as long as that refarmation does not atter the fundamentals of Islam.

Evaluation of Locally Isolated Lactobacillus Species As Probiotics in Broiler Chicken

Lactobacilli are the most important bacteria gaining more consideration in the area of probiotics because they are generally regarded as safe. The present study was conducted to isolate and characterize Lactobacilli from avian microbiota and fermented milk products with the objective to evaluate these isolates as probiotics in broiler chicken. Various Lactobacillus species were isolated and, after characterization and screening, these isolated Lactobacilli were evaluated as probiotics in broiler chicken. A total 240 broiler chicks (day-old) were divided into 8 groups of 30 chicks each with 5 replicates. Six groups were administered isolated Lactobacilli in three dose rates and two routes. In addition, one group was administered commercial probiotics and another one group was maintained as control. Evaluation was done for the determination of effect on different performance parameters and immune response under experimental conditions. The chicks of experimental group, which was given Lactobacilli at dose rate 1x108 CFU/ kg body weight through drinking water, showed significantly (P<0.05) higher body weight, less feed consumption, decreased feed conversion ratio, low mortality and higher dressing percentage. This group also gained significantly (P<0.05) higher post-vaccinal antibody titres. Significantly, higher counts of Lactobacilli and lower count of E. coli were recorded in the intestinal contents of this group than other treated and control group. The treatment also showed similar results under field conditions. The study showed that these locally isolated Lactobacillus species had better effect as probiotics and these are as good as imported ones. It is recommended that these locally isolated Lactobacilli may be used as probiotics after species/strain identification through molecular methods and extensive field trials.
