Harnessing cactus biomass for biogas and biofertilizer production under temporal fermentation strategies

Kenneth Tembe Oduor, José Carlos Batista Dubeux, Willis Owino, Lynn Elwood Sollenberger et autres

Some cactus species are invasive, requiring innovative strategies for control. We evaluated the potential and optimization strategies of cactus (Opuntia spp.) for biogas production. Treatments included: (1) cattle dung + cactus on day 0, (2) cattle dung + cactus on day 0 …

Isolation and Characterisation of Lactic Acid Bacteria Isolated from Artisanal Cheese (Tchoukou) from the Niger Republic

Mahamadou Rabiou Moudi Aboubacar, Issoufou Amadou, Ibrahim Halilou Amadou, Willis Owino et autres

Lactic Acid Bacteria (LAB) are industrially essential microorganisms widely used as starter cultures in the production of dairy, meat, cereal, vegetable, and alcoholic beverages. Beyond their technological role, LAB contribute to human health by enhancing gastrointestinal function, producing antioxidant metabolites, inhibiting pathogenic …

Biochemical and microbiological characterization of Coffea arabica sidestreams for food ingredient applications

Gaston Odiwuor Adoyo, Willis Owino, Elizabeth Wafula, Søren Balling Engelsen et autres

Coffee processing generates substantial waste, with about 94% of the cherry discarded as by-products (skin and pulp ≈ 43%, mucilage ≈ 12%, parchment ≈ 6%, silverskin ≈2%, and spent coffee grounds ≈ 31%). This study presents the first comprehensive biochemical and microbiological …

Forage Systems in Arid and Semiarid Regions

Adesuwa Sylvia Erhunmwunse, A.E.M. Silva, ALBERICIO PEREIRA DE ANDRADE, Alberto Jefferson da Silva Macêdo et autres

Livestock production plays a vital role in many semiarid and arid regions around the world. The semiarid region of Northeastern Brazil, in particular, is the most densely populated of its kind globally. In this context, the book Forage Systems in Arid and …

Mapping invasive Opuntia stricta in Kenya’s Drylands using explainable machine learning with time-series remote sensing and geographic context

Chang Zhao, Kenneth Tembe Oduor, Hao‐Yu Liao, Zhou Tang et autres

Opuntia stricta is a globally widespread invasive species that degrades dryland ecosystems and threatens pastoral livelihoods. Accurate, high-resolution distribution maps are essential for effective management, but its spectral similarity to native vegetation complicates remote sensing-based classification. We developed an interpretable Random Forest …

Chitosan-phenyllactic-acid coating reduces anthracnose and modulates defense gene expression in Hass avocado fruits

Hamza Alassan Hamidou, S. K. Kimaru, Willis Owino

• CHI–PLA coating significantly reduced anthracnose incidence and severity in avocado fruits. • The CHI-PLA induced an upregulation of chitinase gene and downregulation of lipoxygenase • The CHI–PLA mixture exhibited an additive effect in controlling Colletotrichum gloeosporioides. • CHI–PLA formulation shows promise …
