Proteases or peptidases constitute the largest group of enzymes in bio-industry with a long array of uses. They play an invincible role in industrial biotechnology, especially in detergent, food and pharmaceutical arena. This focused review encompasses an overview on alkaline proteases, mainly of microbial sources in a handy module. Following an introduction and general classification with evol...

Abstract Tannery wastewater is a complex mixture of organic and inorganic components from various processes with high concentrations Cr, BOD, COD, TDS, strong colour pH. The goal the present work was to determine optimal solar photo-assisted electrochemical peroxidation process (SPECP) experimental conditions for treatment tannery wastewater. Experiments were conducted in bench-scale stirred ta...

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

The disposal and treatment of wastes generated in the leather industry has been the focus of several studies around the world. They intend to meet environmental legislation and make the process environmentally and economically viable. The anaerobic digestion process, which occurs in steps that involve acid and methane forming bacteria, can be an alternative since it turns the waste into renewab...

The aim of this study was to measure the incidence of high blood pressure (HBP) in a medium-size tannery in Botucatu, São Paulo State, southeast Brazil. A previous study at this tannery showed a high prevalence of arterial hypertension. A positive correlation was found between cumulated work time and arterial pressure. We followed a cohort of workers for seven years. At the end of this period, ...

Background: Tannery industry produces high amounts of nutrient rich sludges that can be used as organic fertilizers. Objective: The aim this study was to evaluate the fertilizing potential composted tannery sludge. Methods: A pot experiment carried out with ryegrass ( Lolium perenne L.) test two different composts: 2.0 kg dry matter (DM) fatty sludge + 1.5 DM sheep manure wheat straw (Compost 1...

The levels of cadmium (Cd) in soil and commonly consumed tomato (Lycopersicon csculentum Miller) fruits grown around the industrial areas Dhaka Narsingdi districts Bangladesh were quantified compared with FAO/WHO (2003)safety limits. According to findings, order Cd concentration soils was found Textile > Pharmaceutical Tannary industry. (mg/l) ranged from 0.24 0.91 0.15 0.74, respectively. E...

BACKGROUND This study aimed to estimate the prevalence and to identify some risk factors of adult asthma in male leather tannery workers in Karachi, Pakistan. METHODS A cross sectional study was conducted from August 2003 to March 2004 on leather tannery workers of Karachi, Pakistan. Data were collected from 641 workers engaged in 95 different tanneries in Korangi industrial area selected as ...

Here we present the complete 1,424,912-bp genome sequence of Coprothermobacter proteolyticus DSM 5265, isolated from a thermophilic digester fermenting tannery wastes and cattle manure.

BACKGROUND Animal skin provides an ideal medium for the propagation of microorganisms and it is used like raw material in the tannery and footware industry. The aim of this study was to evaluate and identify the microbial load in oropharyngeal mucosa of tannery employees. METHODS The health risk was estimated based on the identification of microorganisms found in the oropharyngeal mucosa samp...
