protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtain...

BACKGROUND Hair is composed mainly of keratin protein and a small amount of lipid. Protein hydrolysates, in particular those with low molecular weight distribution have been known to protect hair against chemical and environmental damage. Many types of protein hydrolysates from plants and animals have been used in hair and personal care such as keratin hydrolysates obtained from nails, horns an...

EXTENDED ABSTRACT The method of new NKSMg fertilizer based on utilization of feather waste from slaughterhouses was presented. The method allows the production of liquid fertilizers which can be used in soil and foliar application. The whole process is based on the digestion of feather waste by acid hydrolysis, adjusting pH of the reaction medium, and then enriched in selected nutrients. Pot ex...

Several protein sources were tested as deer repellents with captive deer. Black-tailed deer were offered Western redcedar seedlings treated with corn gluten meal, feather meal, poultry blood, hydrolyzed casein, or a control (latex sticker used for treatment proteins). After 37 days, feather meal and hydrolyzed casein provided equivalent protection against browse damage (only 23% of seedlings si...

Bacillus thuringiensis subsp. israelensis is the leading biopesticide in world due to its specificity and lack of toxicity. The use Bti still restricted developing countries bioprocess complications high cost production. In present study we have shown that lignocellulosic agro waste residues like rice straw can be used as effective substrates with appropriate chemical treatment methods. We comp...

There are several reports about the optimization of protease production, but only few have optimized the production of organic solvent tolerant keratinolytic proteases that show remarkable exploitation in the development of the non-polluting processes in biotechnological industries. The present study was carried with aim to optimize the production of a thermostable organic solvent tolerant kera...
