میر علی محمد شادؔ

جناب میر علی محمد شادؔ مرحوم عظیم آبادی

ابھی نثر اردو کے ماتم سے ہم فارغ نہیں ہوئے تھے کہ نظم اردو کے پرانے استاد عظیم آباد کے مشہور باکمال شاعر میر علی محمد شاد کی موت کی خبر آئی، ۸؍ جنوری ۱۹۲۷؁ء کو غالباً ۸۲ برس کی عمر میں اپنے وطن عظیم آباد پٹنہ میں وفات پائی، ساٹھ برس سے زیادہ کی مشق سخن تھی، لاکھوں شعر ان کے نتائج فکر ہیں، میرؔ اور انیسؔ کے مقلد اور متبع تھے، اس دور میں وہ یورپ میں زبان اردو کے تنہا استاد رہ گئے تھے، ہموطنی کے باوجود کبھی ان کی ملاقات کا شرف حاصل نہ ہوسکا، البتہ تحریری نیاز ایک مدت سے جاری تھا، کچھ دنوں سے ہوش و حواس بھی بجانہ تھے، تاہم شعر برابر وردِ زبان تھا:
آخر ہے عمر ، ضیق میں ، دل بھی ہے جان بھی
مردانہ باش! ختم ہے یہ امتحان بھی!!
مرحوم کی تصنیفات میں دیوان اور کلام منظوم کے علاوہ نوائے وطن وغیرہ نثر کی کتابیں بھی ہیں، مرحوم کا ایک طویل والا نامہ بھی میرے پاس رکھا ہے، جس میں اپنی تصنیفات کی پوری کیفیت لکھی ہے، افسوس کہ ان کا پورا کلام کوششوں کے باوجود بھی یک جاہوکر طبع نہ ہوسکا، جو کام کہ ان کی غایت احتیاط کی بناء پر ان کی زندگی میں نہ ہوسکا، شاید اب ان کے مرنے کے بعد انجام کو پہنچ جائے، اپنے طرز کے وہ تنہا مالک تھے اور زمانہ کا رنگ دیکھ کر توقع نہیں کہ اس طرز کا سخن ور پھر پیدا ہوسکے۔
(سید سليمان ندوی، جنوری ۱۹۲۷ء)

Comprehensive overview on Bacillus subtilis antibacterial metabolites production Bacillus Subtilis Antibacterial Metabolites Production

Over the last 70 years, Food processors and the plant protection sector have both benefited from Bacillus subtilis. Their capacity to manufacture endospores for survival, as well as a multitude of antimicrobial substances has piqued industrial interest in areas such as food preservation, medicinal agents, and biopesticides. In light of the growing trend of food healing and the protection of bacterial plants, this review suggests a holistic approach to visualizing the antimicrobial screen described in Group B. This review aims to make easy and updated classification of antimicrobial metabolites in group B. Subtilis, its complex phylogeny that tends to perpetuate development.

Spatial and Temporal Variation in Heavy Metal Toxicity and its Impact on the Ecosystem of Indus River

The Indus River is major freshwater resource for Pakistan’s 160 million people for its goods (e.g. edible fishes & water for irrigation purpose) and services (recreational, hosting migratory birds of high ecological importance).Increasing heavy metals level due to industrial and urban activities in the catchment of Indus River is a serious environmental issue with regard to health of aquatic food chain. Comprehensive investigation of heavy metal contamination in the water, sediment, aquatic plants and freshwater fishes of Indus River was needed for evaluating current heavy metal level buildup along food chain, developing necessary mitigation measures against increasing metal level for reduction of impacts on its ecosystem health and conservation of goods & survives of Indus River. The present study was conducted at three sampling sites of the Indus River including two sites (Chashma barrage and Taunsa barrage) which are “RAMSAR sites” internationally important for conservation point of view. Samples of water, sediments, aquatic plants and three commercially important freshwater fish species (Labeo rohita, Cyprinus carpio and Wallago attu) were collected on seasonal basis. Physico-chemical water quality parameters were measured in the field and Lab. Heavy metal levels were analyzed by Atomic Absorption Spectrophotometer (AAS). Ecological risk assessment of heavy metals in Abiotic media (water & sediments), aquatic plants and human health risk of fish consumption were done respectively. Heavy metals in different compartments of River Indus were found in the order of Sediment>Aquatic plants>Fish>Water. Concentration of Cr and Pb in many of water samples of Chashma and Taunsa Barrage and As concentration at Mithan kot was higher than recommended WHO water quality guidelines although these were lower than National environmental quality guidelines of Pakistan. Ecological risk evaluation through metal content of sediments depicts that in sediments, Fe concentration at Taunsa barrage, Cu concentration at Chashma barrage, Ni, Hg and Pb at Mithan kot were higher than recommended International Sediment Quality Guidelines that can pose serious risk of adverse ecological effects. Bioaccumulation factor [AF] of various parts of aquatic plants species (Typha angustifolia and Pistia stratiotes) in relation to the sediment metal concentration of Indus River was calculated which ii shows that [AF] root ratios for Typha aungustifolia was high compared to the root ratios for Pistia Stratiotes. This difference was highest in the autumn and winter seasons. Root system of both plant species was the target part for heavy metal accumulation that concentrates highest metal concentrations in it compared to leaves and stem that accumulated comparatively lower metal content. Irrespective of inter-specific metal differences, heavy metal concentrations in the root systems of both species significantly varied on seasonal basis. Carnivorous fish (Wallago attu) accumulated more heavy metal when juxtaposed with herbivorous (Labeo rohita) & omnivorous fish (Cyprinus carpio). Heavy metal levels in non-edible tissues (liver and gills) were higher than permitted level of the heavy metals by FAO. In few samples of muscle tissues, Zn concentration in all of three fish species and Cr in Wallago attu were higher than recommended FAO limits. Health risk assessment suggested that although current levels of heavy metal in fish tissues cannot pose health risk to native human communities, but these metal contents are continuously increasing. It is recommended that Cr, Hg, Pb and Zn levels should be monitored in fish tissues on regular basis as these metals have the potential to pose adverse health effects to human in future. Heavy metal concentrations especially in water and sediments of Indus River were higher in low flow season of Indus River compared with international acceptable and safe limits, this may pose serious health threats through fish consumption, and can affect water use for recreational and irrigation purposes. This is utmost important for government institutions to conduct risk assessment studies or adopt intervention strategies for restoration and management of the Indus River.
