For centuries, some Indigenous Peoples of the Americas have planted corn, beans and squash or pumpkins together in mounds, in an intercropping complex known as the Three Sisters. Agriculturally, nutritionally and culturally, these three crops are complementary. This literature review aims to compile historical foods prepared from the products of the Three Sisters planting system used in Indigenous communities in the region encompassing southern Quebec and Ontario in Canada, and northeastern USA. The review does not discuss cultural aspects of the Three Sisters cropping system or describe foods specific to any one Indigenous group, but rather, gives an overview of the historical foods stemming from this intercropping system, many foods of which are common or similar from one group to another. Some of the methods of food preparation used have continued over generations, some of the historical foods prepared are the foundation for foods we eat today, and some of both the methods and foods are finding revival.

La presente Ctude s'inscrit ii I'intkrieur de travaux de dCveloppement d'un procedk de traitement des eaux usCes permettant aussi la recuperation des Cltments nutritifs contenus dans les effluents de I'industrie agro-alimentaire. Un effluent d'abattoir a CtC soumis B une sCrie d'essais a I'Cchelle du laboratoire a des tempkratures de 45, 52 et 58°C. L'efficacite du procCdC sur le plan traitement a kttC dkmontrke par l'enlevement de plus de 90% de la demande chimique en oxyghe (DCO) pour tous les temps de sCjour CtudiCs (6, 12, 18, 24 et 30 heures) 21 45 et 52°C. Le contenu en proteines brutes de la biomasse recueillie atteignait en moyenne pres de 70% sur une base &he, et la composition en acides aminks de la protkine s'est rhCIee adequate pour introduction B titre de concentre dans les rations alimentaires du porc et de la volaille.This study fits into the scheme of research work being carried out to develop a wastewater treatment process for the food industry with the possibility of recycling nutrients as a proteinic biomass. A slaughterhouse effluent was submitted to a series of laboratory tests at temperatures of 45, 52 and 58°C. The treatment efficiency was demonstrated by a 90% reduction of chemical oxygen demand (COD) for studied retention times (6, 12, 18, 24 and 30 hours) at 45 and 52°C. The crude protein content collected reached an average of nearly 70% dry basis, and the amino-acids composition was proven adequate for use as protein concentrate for pig and poultry feedings.Keywords: food industry, slaughterhouse effluent, wastewater treatment, thermophilic bacteria, biomass recycling. es eaux ustes de I'industrie agro-alimentaire sont loin THE
