      A kraft pulp mill can be divided into four main parts: (1) raw material handling; (2) pulping line with an almost closed chemical and energy recovery system; (3) bleaching with an open water system and (4) the external wastewater treatment system.

The objectives of this study were to evaluate the feeding value and potential toxicity of single cell protein (SCP) when fed to ruminants.

Three in vivo digestibility trials with lambs, one feedlot trial with steers and one long term feeding trial of high levels of SCP with sheep were conducted to accomplish the objectives of this : Osman Bin Atil.

A study of feeding value and potential toxicity of pulp mill single cell protein in ruminants. Abstract. Graduation date: The objectives of this study were to evaluate the feeding value\ud and potential toxicity of single cell protein (SCP) when fed to\ud ruminants.\ud Three in vivo digestibility trials with lambs, one feedlot trial.

When used as animal feed, toxicity levels are generally higher than when consumed by humans. Based on in vitro and laboratory results the SCP from secondary clarifiers of pulp mill had the potential to be a viable protein supplement for live stock. M.S. Aseltine, D.C.

Some of these waste residues, especially the Kraft pulp mill rejects, appear to be promising sources of substrate for single-cell protein production. In these preliminary findings, up to 28% dry weight crude protein content of the product has been obtained at specific growth rates of up to hr −1 on direct utilization of the wastes.

In view of this, the present study investigates the effects of pulp and paper-mill effluents on male rats, particularly with respect to their reproductive system. Materials and methods Effluent samples.

The outcomes of the project may contribute to the introduction and development of a new sustainable and non-volatile single-cell protein ingredient for commercial use in fish and piglet feed.

Essentially, it may become an alternative to overexploited protein sources such as. The review of pulp and paper mill effluents considers the need for additional toxicity data to insure effective effluent regulation.

Effluent characteristics and problems of toxicity testing particular to pulp and paper mill effluents are discussed; however, the emphasis is on toxic effects of these effluents to aquatic life.

Untreated pulp and paper mill effluents are very toxic to most. The present study, thus, is an attempt in reviewing toxic effects of paper mill effluents in fish. ACUTE TOXICITY AND BEHAVIOURAL RESPONSE The static bioassay procedures to study the toxicity of pulp and paper mill effluent to a variety of fishes have been reported [10].

The toxicity, in terms of LC 50 values, was found to vary a great deal. Pulp and paper mill effluents are complex mixtures of dissolved lignin and cellulose degradation products and other substances extracted during the pulping process.

The toxicity of these effluents to fish has been documented (Howard and Walden, ; Wande, ; Walden and Howard, ). As fish meal and soybean meal are by far the most widely used protein sources in animal feed all over the world, the fungal biomasses obtained from this study were compared to these commercial protein-rich meals in terms of main components, amino acids, fatty acids, minerals contents, and gross energy.

Osman Bin Atil has written: 'A study of feeding value and potential toxicity of pulp mill single cell protein in ruminants' -- subject(s): Feeding and feeds, Ruminants, Proteins in animal nutrition. The results showed that autochthonous bacteria isolated from the site of pulp and paper mill have the ability to use lignin, tannic acid, xylan, and cellulose as carbon source and reduce the COD value up to % (back water) and 65% ( 20, back water and black liquor mixture) of effluent generated from small (agro-based) pulp and paper.

The aim of this study was, therefore, to evaluate the performance of the sMBR treating paper mill industry wastewater and to focus on physico-chemical properties of activated sludge, such as extracellular polymeric substances (EPS), soluble microbial products (SMP), protein and carbohydrate, relative hydrophobicity (RH), zeta potential, and.

Single cell protein (SCP) derived from secondary clarifiers of pulp mills is a potential commercial protein supplement in many areas. Treatment of the meal with iron salts eliminates the toxicity of gossypol, but also produces a darker meal which is unacceptable to the feed industry (see Table 1).

Treatment of cottonseed meal with phytase increases the availability of phosphorus, reduces gossypol toxicity, and increases the availability of some proteins.

Table 1. The single cell protein used was generated through an aerobic fermentation process and dried to create a flour designated as KnipBio Meal (KBM), said the researchers in the study. The salmon diets were composed to examine the digestibility of KBM compared to .improve nutritive value The greatest potential for using alternative feedstuffs is in the feeding of layers, irrespective of the production system.

Owing to physiological differences, pullets and layers are more tolerant to high fibre, poor-quality feedstuffs and nutritional challenges than fast-growing meat birds are.

Some of these feedstuffs can.A number of the feedstuffs used to supply supplementary protein to poultry diets may contain naturally occurring toxic or potentially toxic compounds.

In many instances, the nutritive value of the protein supplement can be markedly influenced by the method used in processing the protein supplement.
