Background: Indian domesticated chickens have a wide variety of phenotypes. Unlike other chicken breeds, Kadaknath chicken has black meat and is used by indigenous tribal people for its invigorating and therapeutic properties. To look for the functional traits that might be contributing towards the acclaimed benefits, free radical scavenging capacity and metal chelating ability of Kadaknath meat were explored for the first time in comparison to the commercial Cobb broiler. Methods: During the period 2018-2020, breast and thigh meat were collected from chickens (n=20/ group) at their commercial slaughter age. Meat extract was used for qualitative evaluation of protein as well as the antioxidant capacity utilizing diverse in vitro methods corresponding to different antioxidation mechanisms.Result: Protein concentration (g/100g of tissue) in Kadaknath breast (25.25 ± 0.31) and thigh (19.98 ± 0.29) meat was significantly (P less than 0.05) higher than the Cobb. Breast meat had better sc...

Background: New chicken breeds are being evolved for backyard rural poultry production to overcome the slow growth, late sexual maturity and poor production of indigenous breeds. However, autochthonous poultry is epitomized for quality attributes of their products. With this in mind, the present study for the first time explored the antioxidant capacity of meat obtained from a unique Indian chicken, Kadaknath and a synthetic breed of poultry, Jabalpur colour (JBC). Methods: During the period 2018-2020, breast and thigh meat were collected from chickens (n=20/ group) at their commercial slaughter age (20 weeks). Meat extract was used for qualitative evaluation. Antioxidant activity was explored using five well established in vitro methods testing for different antioxidant mechanisms. Result: Both, Kadaknath and JBC meat was proteinaceous with higher protein concentration (g/100 g of wet weight) in the breast (Kadaknath, 25.21±0.31 and JBC, 25.65±0.39) than the thigh (Kadaknath, 19.98...

Among different types of enzymes obtained from microbial sources, amylases are the most widely used in industries as well as on commercial basis. Amylase production from bacteria is economical as the enzyme production rate is higher in bacteria as compared to other microorganism. The aim of the current study was to isolate amylase producing bacteria from the soil samples collected from potato field of north India. The isolation was done by serial dilution and plating method. Total 30 bacterial colonies were isolated from the collected soil samples. All isolates were screened for amylolytic activity by starch agar plate method. Among 16 bacterial isolates, only 6 isolates showed the amylolytic activity. Out of these, one isolate was selected on the basis of maximum hydrolysis for further study. The 16S rRNA sequences of selected strain was isolated and sequenced. The isolate was identified as Bacillus amyloliquefaciens on the basis of morphology, biochemical tests and 16S rRNA sequen...
