The food industry faces numerous challenges to assure provision of tasty and convenient food that possesses extended shelf life and shows long\uffe2\uff80\uff90term high\uffe2\uff80\uff90quality preservation. Research and development of antimicrobial materials for food applications have provided active antibacterial packaging technologies that are able to meet these challenges. Furthermore, consumers expect and demand sustainable packaging materials that would reduce environmental problems associated with plastic waste. In this review, we discuss antimicrobial composite materials for active food packaging applications that combine highly efficient antibacterial nanoparticles (i.e., metal, metal oxide, mesoporous silica and graphene\uffe2\uff80\uff90based nanomaterials) with biodegradable and environmentally friendly green polymers (i.e., gelatin, alginate, cellulose, and chitosan) obtained from plants, bacteria, and animals. In addition, innovative syntheses and processing techniques used to obtain active and safe packaging are showcased. Implementation of such green active packaging can significantly reduce the risk of foodborne pathogen outbreaks, improve food safety and quality, and minimize product losses, while reducing waste and maintaining sustainability.Seasonal Distribution And Abundance Of Earthworms (Annelida: Oligochaeta) In Relation To The Edaphic Factors Around Udupi Power Corporation Limited (Upcl), Udupi District, Southwestern Coast Of India", "description": "
Seasonal distribution and abundance of four species of earthworms belonging to three families\uffe2\uff80\uff94Rhinodrilidae (Pontoscolex corethrurus), Megascolecidae (Megascolex konkanensis and Metaphire houlleti) and Octochaetidae (Karmiella karnatakensis)\uffe2\uff80\uff94were studied in three habitats (residential, agricultural and forest) along with edaphic factors around Udupi Power Corporation Limited (UPCL), Karnataka, India between September 2014 and August 2016.\uffc2\uffa0 Among the four species, P. corethrurus was collected throughout the year and was most abundant in residential habitats such as colacasia garden, coconut and banana pits.\uffc2\uffa0 M. konkanensis was collected from coconut plantations, banana plantations and forest soil during monsoon and post-monsoon periods.\uffc2\uffa0 M. houlleti was collected from manure heaps, coconut and banana pits of residential habitat, coconut plantations and forest soil.\uffc2\uffa0 K. karnatakensis was collected from garden soil in residential habitat during the post-monsoon period, coconut plantations and soil mixed with forest leaf litter during monsoon and post-monsoon periods.\uffc2\uffa0 The soil temperature differ significantly during different seasons in residential (P= 0.01) and agricultural (P=0.03) habitats whereas moisture shows highly significant difference in agricultural habitat (P=0.00037) during different seasons.\uffc2\uffa0 P. corethrurus showed positive correlation with organic carbon during pre-monsoon and C/N ratio during monsoon in the residential habitat.\uffc2\uffa0 It shows negative correlation with pH during the monsoon period.\uffc2\uffa0 M. houlleti showed positive correlation with organic carbon in residential habitat during the pre-monsoon and in forest habitat during monsoon periods.\uffc2\uffa0 M. konkanensis showed positive correlation with electrical conductivity in agricultural habitats during monsoon period.\uffc2\uffa0 K. karnatakensis showed positive correlation with moisture during monsoon and with C/N ratio during post-monsoon period in forest habitats.
