Biological nitrogen fixation (BNF) is easily the most studied microbial process applied to agriculture. It consists of the reduction of atmospheric dinitrogen (N2), unavailable to higher plants, into ammonium (NH4+), an assimilable form of this nutrient. The BNF process is performed solely by microorganisms, the majority inhabiting the soil ecosystem, and is considered to be the most relevant component of the global nitrogen cycle (Ishizuka, 1992). The best known diazotrophs (dinitrogen fixing bacteria) are rhizobia, which are able to establish a symbiotic relationship with plants of the family Leguminosae, hereby called legumes. This symbiosis is characterized by a highly specific association between plant and bacteria. Particular varieties of legume species recognize specific strains of rhizobia, which are able to infect the legume roots. This process triggers the expression of certain plant genes, resulting in the development of nodules around the site of invasion. In the interior of the nodules the bacteria undergo morphological and physiological transformations, becoming nitrogen fixing bacteroides and supplying the plant with nutrient in exchange for carbon-rich material derived from plant photosynthesis. |

The aim of the present study was to characterize the physical-chemical and sensory attributes of two papaya varieties (Aliança and Golden THB) (Carica papaya L.) coated with different solutions of manioc starch and clove essential oil (Syzygium aromaticum L. Merr. et Perry). Four different treatments were studied in papaya fruits at ripening stage 1: T0 (control); T1 (fruits coated with a solution of manioc starch); T2 (fruits coated with clove essential oil at 0.175 mL L-1); T3 (solution of manioc starch with clove essential oil-0.175 mL L-1). The physical-chemical and sensory analyses were conducted in the fruits at ripening stage 5. The edible coatings did not influence the physical-chemical characteristics of the two varieties. Those fruits coated with manioc starch reported a good sensory acceptance not differing statistically from the control fruits in the majority of the attributes studied. By evaluating the purchase intention regarding the variety Aliança, all the treatments reported good levels of acceptance, with higher scores in the option "would certainly buy". After the sensory evaluation, treatment T3 reported a purchase intention of 80%. It was concluded that the edible coatings did not influence the physical-chemical characteristics of the fruits, however, they influenced the sensory acceptance of the tasters. For the variety Aliança, the application of treatment T3 is recommended, while for Golden THB, treatments T1 and T2 are recommended due to their similarity to the control.
