The effectiveness of a commercial inoculum for degrading a dairy wastewater with high fat content was evaluated, and compared with an activated sludge inoculum from a dairy wastewater treatment pond. Both inocula reached similar chemical oxygen demand removal in batch experiments. The population dynamics was also studied by determining heterotrophic counts. Predominant microorganisms were differentiated by colony morphology and genomic fingerprinting (BOX-PCR) analysis. The higher population diversity and the wider range of CO2 production rate observed in batch reactors inoculated with activated-sludge, indicated that microorganisms from this inoculum were well adapted and may have had synergic activity for the degradation of the dairy effluent. When the bioreactor was operated with the commercial inoculum in continuous mode, according to its microbial growth kinetics, other microorganisms became predominant. These results showed that inoculated microorganisms did not persist in the open system and periodic addition of microorganisms may be needed to achieve a high performance treatment.

Wheat is an important cereal crop globally and in the United States, and is the largest crop grown by acreage in Colorado. In June 2023, we observed wheat fields displaying severe yellowing and virus-like disease symptoms in plants across seven eastern Colorado counties (Yuma, Prowers, Kit Carson, Washington, Sedgewick, Morgan, and Weld). Symptomatic plants were prominent in fields and appeared bright yellow, with ringspots, mosaic patterning, and streaking on leaves.

African eggplant (Solanum aethiopicum gilo group) is a nutritious vegetable widely commercialized in Ghana. In the 2021 planting season (May-July), collar rot symptoms were observed on African eggplant on a farm at Domeabra, Legon, and Okumaning in the Central (N5° 48' 11″, W1° 26' 48″), Greater Accra (N5° 39' 34″, W0° 11' 34″) and Eastern (N6° 8' 34″, W0° 55' 59″) regions of Ghana, respectively. Disease incidence was 8-15% in the different farms.

Introduction: Rice, particularly Basmati rice, holds significant global importance as a staple food. The indiscriminate use of phosphate-based fertilizers during rice production has led to high residual levels of these chemicals in soil, impacting soil health and fertility. This study aimed to address this challenge by investigating the potential of phosphate solubilizing bacteria (PSB) in improving soil fertility and boosting the growth of Basmati rice.
