Gelatin has been widely used as an additive in food industry pharmaceutical, and  cosmetic. The similar physical appearance between bovine and porcine gelatin causes an issue for some communities like a Muslim due to awareness of halal food. This study aims to produce gelatin from femur bones of bovines with acid hydrolysis and their characteristics compared to standard gelatin of bovine and porcine. Bovine and porcine bones were soaked in 5% HCl for 10 days and every 2 days a HCl solution was replaced to get ossein. Ossein is hydrolyzed by gradual heating at 65, 75, and 85oC. Gelatin  confirmed by  the physico-chemical characters, FT-IR and analysis amino acid with HPLC.The results showed that the yield of bovine gelatin was 4.33%. The physico-chemical characters of bovine gelatin resulting from isolation and bovine gelatin standards are in conformity with porcine gelatin standards and meet the requirements of SNI 06-3735-1995 and GMIA. Therefore, bovine gelatin is specifically capable of substituting porcine gelatin for application in the pharmaceutical field. The FTIR spectrum of bovine gelatin shows the presence of amide A, amide I, amide II and amide III groups. The amino acid characters of gelatin were identified as glycine (13.57%) and proline (1.62%) for bovine gelatin and glycine (0.51%) and proline (0.09%) for porcine gelatin.

Physico-chemical (pH, conductivity, dissolved oxygen, alkalinity, hardness, nitrogen, heavy metal, etc) and bacteriological (coliform bacteria) characteristics of water were studied in samples collected from Sundarijal reservoir and its main feeding streams: Bagmati, Nagmati and Shyalmati in 2003 and 2004 AD. Human activities near the water bodies and sanitary condition of the residential areas of watershed were also examined. Although public awareness and proper management of watershed and reservoir premises were lacking, yet the physico-chemical characters were within the standard of World Health Organization (WHO) and European Commission (EC) for drinking water. However, the coliform bacteria were high and water was not safe to consume without intense treatments with disinfectants.

The ratooning ability of five Iranian rice cultivars and the grain quality of the ratoon crop were evaluated in a randomized complete block design with four replications in consecutive years from 1999 to 2001 to select promising lines for economical ratoon culture. The main crop was harvested by cutting 30 cm above the soil surface for regrowth of the second (ratoon) crop. The ratoon grain yields (kg/ha) varied greatly among the cultivars, ranging from 144.9 (Haseni) to 1472.1 (Sang-e-Tarom). In general, the ratoon crops had fewer fertile spikelets, fewer spikelets per panicle, shorter panicle length and fewer primary and secondary branches per panicle than the main crop. The gelatinization temperature and gel consistency of rice grains from ratoon crops were lower than those of the main crops. The amylose content (%) of the grains from ratoon crops varied from 23.1 (Sang-e-Tarom) to 21.4 (Dailamani).

Ten sediment samples were gathered from several geographical locations around mangrove habitat, Red Sea coast, Egypt, during summer 2019. Actinobacteria are widespread in most mangrove soil samples. The average actinomycetes counts in sediment samples were ranged from 4 to 15 CFUg-1, also physico-chemical characters for soil samples were determined. Statistical analysis was applied to assess if the geographical location and physico-chemical characters influenced the communities of actinomycetes. A total of 10 actinomycetes were isolated and characterized physiologically and biochemically. The antimicrobial activities of different actinomycetes isolates were assessed. Isolate M3 was chosen as the most promising isolate with broad antagonistic activity against Bacillus subtilis ATCC 6633, Escherichia coli ATCC 19404, Staphylococcus aureus ATCC6538, Pseudomonas aeruginosa ATCC 9027, and Candida albicans ATCC 10231 with inhibition zones ranged from 12.0 ± 0.9 to 20.0 ± 1.9 mm. Genotypic characterization of isolate M3 was made using 16S rDNA sequence analysis and identified as Streptomyces mutabilis M3 with accession number MT483919. This strain exhibited anticancer activity against breast cancer cell line (Mcf7), liver cancer cell line (HepG2) and colon cancer cell line (HCT116) and the IC50 values were 324.77, 333.71 and 354.46, respectively. Streptomyces mutabilis M3 MT483919 had high bio-flocculating activity for seawater treatment, and the recovery of the samples ranged between 71.97 and 76.05%. The crude extract of Streptomyces mutabilis MT483919 M3 was analyzed by Fourier transform infrared spectrum (FT-IR) and Gas chromatography-mass spectrometry (GC-MS).
