Replacing harmful chemical pesticides with compost extracts is steadily gaining attention, offering an effective way for plant growth enhancement and disease management. Food waste has been a major issue globally due to its negative effects on the environment and human health. The methane and other harmful organisms released from the untreated waste have been identified as causes of this issue. Soil bacteria impart a very important role in biogeochemical cycles. The interactions between plants and bacteria in the rhizosphere are some of the factors that determine the health and fertility of the soil. Free-living soil bacteria are known to promote plant growth through colonizing the plant root. PGPR (Plant Growth Promoting Rhizobacteria) inoculants in compost are being commercialized as they help in the improvement of crop growth yield and provide safeguard and resistance to crops from disease. Our focus is to understand the mechanism of this natural, wet waste recycling process and implementation of a sustainable operative adaptation with microbial association to ameliorate the waste recycling system.

Autism Spectrum disorder (ASD) is a neurodevelopmental disorder presenting with defects in social communication skills and repetitive sensory motor behaviour. There has been increasing concern regarding this disorder due to its increase in incidence and prevalence in recent years. Since it stays for lifelong and has no specific pharmacological treatment, many studies are being conducted to find ways of preventing this disorder. Better understanding of the causative factors will lead to better development of prevention strategies. This review aims at highlighting the methods of prevention of ASD which are mostly focussed on the environmental factors causing ASD as well as the ongoing researches on development of drugs and genetic modification using animal models. Some studies have shown preventive effects of factors such as nutrition supplements such as Vitamin D and folate, breastfeeding and avoiding exposure to harmful chemicals and drugs. The aim is to prevent the occurrence of the disorder and preventing the severity of symptoms wherever possible. Still more studies are needed to establish the exact association between the possible causative factors and ASD so that clinical trials can be done to establish the preventive effects in future.
